2.2 Description
The TMS320C64x DSPs (including the TMS320C6418 device) are the highest-performance fixed-point
DSP generation in the TMS320C6000 DSP platform. The TMS320C6418 (C6418) device is based on the
second-generation high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture
(VelociTI.2) developed by Texas Instruments (TI). The high-performance, lower-cost C6418 DSP enables
customers to reduce system costs for telecom, software radio, Digital Terrestrial Television Broadcasting
(DTTB), and digital Broadcast Satellite/Communication Satellite (BS/CS) applications. The C64x is a
code-compatible member of the C6000 DSP platform.
With performance of up to 4800 million instructions per second (MIPS) at a clock rate of 600 MHz, the C6418
device offers cost-effective solutions to high-performance DSP programming challenges. The C6418 DSP
possesses the operational flexibility of high-speed controllers and the numerical capability of array
processors. The C64x DSP core processor has 64 general-purpose registers of 32-bit word length and eight
highly independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs)—
with V elociTI.2 extensions. The VelociTI.2 extensions in the eight functional units include new instructions
to accelerate the performance in video and imaging applications and extend the parallelism of the VelociTI
architecture. The C6418 can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of
2400 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4800 MMACS. The C6418
DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar
to the other C6000 DSP platform devices.
The C6418 device has a high-performance embedded coprocessor [Viterbi Decoder Coprocessor (VCP)] that
significantly speed up channel-decoding operations on-chip. The VCP operating at CPU clock divided-by-4
can decode over 500 7.95-Kbps adaptive multi-rate (AMR) [K = 9, R = 1/3] voice channels. The VCP supports
constraint lengths K = 5, 6, 7, 8, and 9, rates R = 1/2, 1/3, and 1/4, and flexible polynomials, while generating
hard decisions or soft decisions. Communications between the VCP and the CPU are carried out through the
EDMA controller.
Description
The C6418 uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The
Level 1 program cache (L1P) is a 128-Kbit direct mapped cache and the Level 1 data cache (L1D) is a 128-Kbit
2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 4-Mbit memory space that is
shared between program and data space. L2 memory can be configured as mapped memory, cache (up to
256K bytes), or combinations of the two. The peripheral set includes: two multichannel buffered audio serial
ports (McASPs); two inter-integrated circuit bus modules (I2Cs) ; two multichannel buffered serial ports
(McBSPs); three 32-bit general-purpose timers; a user-configurable 16-bit or 32-bit host-port interface
(HPI16/HPI32); a 16-pin general-purpose input/output port (GP0) with programmable interrupt/event
generation modes; and a 32-bit glueless external memory interface (EMIFA), which is capable of interfacing
to synchronous and asynchronous memories and peripherals.
Each McASP port supports one transmit and one receive clock zone, with six serial data pins which can be
individually allocated to any of the two zones. The serial port supports time-division multiplexing on each pin
from 2 to 32 time slots. The C6418 has sufficient bandwidth to support all six serial data pins transmitting a
192-kHz stereo signal. Serial data in each zone may be transmitted and received on multiple serial data pins
simultaneously and formatted in a multitude of variations on the Philips Inter-IC Sound (I
2
S) format.
In addition, the McASP transmitter may be programmed to output multiple S/PDIF, IEC60958, AES-3, CP-430
encoded data channels simultaneously , with a single RAM containing the full implementation of user data and
channel status fields.
McASP also provides extensive error-checking and recovery features, such as the bad clock detection circuit
for each high-frequency master clock which verifies that the master clock is within a programmed frequency
range.
The I2C ports on the TMS320C6418 allows the DSP to easily control peripheral devices and communicate
with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may be used to
communicate with serial peripheral interface (SPI) mode peripheral devices.

CPU (DSP Core) Description
2.4 CPU (DSP Core) Description
The CPU fetches VelociTI advanced very-long instruction words (VLIWs) (256 bits wide) to supply up to
eight 32-bit instructions to the eight functional units during every clock cycle. The V elociTI VLIW architecture
features controls by which all eight units do not have to be supplied with instructions if they are not ready to
execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute
packet as the previous instruction, or whether it should be executed in the following clock as a part of the next
execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The
variable-length execute packets are a key memory-saving feature, distinguishing the C64x CPUs from other
VLIW architectures. The C64x VelociTI.2 extensions add enhancements to the TMS320C62x DSP
VelociTI architecture. These enhancements include:
• Register file enhancements
• Data path extensions
• Quad 8-bit and dual 16-bit extensions with data flow enhancements
• Additional functional unit hardware
• Increased orthogonality of the instruction set
• Additional instructions that reduce code size and increase register flexibility
The CPU features two sets of functional units. Each set contains four units and a register file. One set contains
functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register
files each contain 32 32-bit registers for a total of 64 general-purpose registers. In addition to supporting the
packed 16-bit and 32-/40-bit fixed-point data types found in the C62x VelociTI VLIW architecture, the
C64x register files also support packed 8-bit data and 64-bit fixed-point data types. The two sets of functional
units, along with two register files, compose sides A and B of the CPU [see the functional block and CPU (DSP
core) diagram, and Figure 2−3]. The four functional units on each side of the CPU can freely share the 32
registers belonging to that side. Additionally, each side features a “data cross path”—a single data bus
connected to all the registers on the other side, by which the two sets of functional units can access data from
the register files on the opposite side. The C64x CPU pipelines data-cross-path accesses over multiple clock
cycles. This allows the same register to be used as a data-cross-path operand by multiple functional units in
the same execute packet. All functional units in the C64x CPU can access operands via the data cross path.
Register access by functional units on the same side of the CPU as the register file can service all the units
in a single clock cycle. On the C64x CPU, a delay clock is introduced whenever an instruction attempts to read
a register via a data cross path if that register was updated in the previous clock cycle.
In addition to the C62x DSP fixed-point instructions, the C64x DSP includes a comprehensive collection
of quad 8-bit and dual 16-bit instruction set extensions. These VelociTI.2 extensions allow the C64x CPU
to operate directly on packed data to streamline data flow and increase instruction set efficiency.
Another key feature of the C64x CPU is the load/store architecture, where all instructions operate on registers
(as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data
transfers between the register files and the memory. The data address driven by the .D units allows data
addresses generated from one register file to be used to load or store data to or from the other register file.
The C64x .D units can load and store bytes (8 bits), half-words (16 bits), and words (32 bits) with a single
instruction. And with the new data path extensions, the C64x .D unit can load and store doublewords (64 bits)
with a single instruction. Furthermore, the non-aligned load and store instructions allow the .D units to access
words and doublewords on any byte boundary. The C64x CPU supports a variety of indirect addressing modes
using either linear- or circular-addressing with 5- or 15-bit offsets. All instructions are conditional, and most
can access any one of the 64 registers. Some registers, however, are singled out to support specific
addressing modes or to hold the condition for conditional instructions (if the condition is not automatically
“true”).

August 2004 − Revised January 2006SPRS241D
CPU (DSP Core) Description
The two .M functional units perform all multiplication operations. Each of the C64x .M units can perform two
16 × 16-bit multiplies or four 8 × 8-bit multiplies per clock cycle. The .M unit can also perform 16 × 32-bit multiply
operations, dual 16 × 16-bit multiplies with add/subtract operations, and quad 8 × 8-bit multiplies with add
operations. In addition to standard multiplies, the C64x .M units include bit-count, rotate, Galois field multiplies,
and bidirectional variable shift hardware.
The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results
available every clock cycle. The arithmetic and logical functions on the C64x CPU include single 32-bit, dual
16-bit, and quad 8-bit operations.
The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory.
The 32-bit instructions destined for the individual functional units are “linked” together by “1” bits in the least
significant bit (LSB) position of the instructions. The instructions that are “chained” together for simultaneous
execution (up to eight in total) compose an execute packet. A “0” in the LSB of an instruction breaks the chain,
effectively placing the instructions that follow it in the next execute packet. A C64x DSP device enhancement
now allows execute packets to cross fetch-packet boundaries. In the TMS320C62x/TMS320C67x DSP
devices, if an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in
the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. In the
C64x DSP device, the execute boundary restrictions have been removed, thereby, eliminating all of the
NOPs added to pad the fetch packet, and thus, decreasing the overall code size. The number of execute
packets within a fetch packet can vary from one to eight. Execute packets are dispatched to their respective
functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the
execute packets from the current fetch packet have been dispatched. After decoding, the instructions
simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock
cycle. While most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes,
half-words, or doublewords. All load and store instructions are byte-, half-word-, word-, or
doubleword-addressable.

2.7 EDMA Channel Synchronization Events
The C64x EDMA supports up to 64 EDMA channels which service peripheral devices and external memory .
Table 2−22 lists the source of C64x EDMA synchronization events associated with each of the programmable
EDMA channels. For the C6418 device, the association of an event to a channel is fixed; each of the EDMA
channels has one specific event associated with it. These specific events are captured in the EDMA event
registers (ERL, ERH) even if the events are disabled by the EDMA event enable registers (EERL, EERH). The
priority of each event can be specified independently in the transfer parameters stored in the EDMA parameter
RAM. For more detailed information on the EDMA module and how EDMA events are enabled, captured,
processed, linked, chained, and cleared, etc., see the TMS320C6000 DSP Enhanced Direct Memory Access
(EDMA) Controller Reference Guide (literature number SPRU234).

2.8 Interrupt Sources and Interrupt Selector
The C64x DSP core supports 16 prioritized interrupts, which are listed in Table 2−23. The highest-priority
interrupt is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts
(INT_00−INT_03) are non-maskable and fixed. The remaining interrupts (INT_04−INT_15) are maskable and
default to the interrupt source specified in Table 2−23. The interrupt source for interrupts 4−15 can be
programmed by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector
Control registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

3 Device Configurations
On the C6418 device, bootmode and certain device configurations/peripheral selections are determined at
device reset, while other device configurations/peripheral selections are software-configurable via the
peripheral configurations register (PERCFG) [address location 0x01B3F000] after device reset.
3.1 Device Configuration at Device Reset
Table 3−1 describes the C6418 device configuration pins. The logic level of the AEA[22:19],
TOUT1/LENDIAN, TOUT0/HPI_EN
The logic level on the device configuration pins can be set by using external pullup/pulldown resistors or by
using some control device (e.g., FPGA/CPLD) to intelligently drive these pins. When using a control device,
care should be taken to ensure there is no contention on the lines when the device is out of reset. The
CLKINSEL and OSC_DIS configuration pins should remain driven to the correct levels during device operation
and must only be changed when RESET
are driven after the reset is removed. At this time, the control device should ensure it has stopped driving the
device configuration pins of the DSP to again avoid contention.
Note: If a configuration pin must be routed out from the device, the internal pullup/pulldown (IPU/IPD) resistor
should not be relied upon. TI recommends the use of an external pullup/pulldown resistor.

3.3 Peripheral Selection After Device Reset
HPI, McBSP1, McBSP0, McASP1, McASP0, I2C1, and I2C0
The C6418 device has designated registers for peripheral configuration (PERCFG), device status
(DEVSTAT), and JTAG identification (JTAGID). These registers are part of the Device Configuration module
and are mapped to a 4K block memory starting at 0x01B3F000. The CPU accesses these registers via the
CFGBUS.
The peripheral configuration register (PERCFG), allows the user to control the peripheral selection of the
McASP1, McASP0, I2C1, and I2C0 peripherals. For more detailed information on the PERCFG register
control bits, see Figure 3−1 and Table 3−3.

Device Configurations
3.4 Peripheral Configuration Lock
By default, the McASP1, McASP0, I2C1, and I2C0 peripherals are disabled on power up. In order to use these
peripherals on the C6418 device, the peripheral must first be enabled in the Peripheral Configuration register
(PERCFG). Software muxed pins should not be programmed to switch functionalities during run-time.
Care should also be taken to ensure that no accesses are being performed before disabling the
peripherals. To help minimize power consumption in the C6418 device, unused peripherals may be disabled.
Figure 3−2 shows the flow needed to enable (or disable) a given peripheral on the C6418 device.

A 32-bit key (value = 0x10C0010C) must be written to the Peripheral Configuration Lock register
(PCFGLOCK) in order to unlock access to the PERCFG register. Reading the PCFGLOCK register
determines whether the PERCFG register is currently locked (LOCKSTAT bit = 1) or unlocked (LOCKSTAT
bit = 0), see Figure 3−3. A peripheral can only be enabled when the PERCFG register is “unlocked”
(LOCKSTAT bit = 0).

BIT NAME DESCRIPTION

31:0 LOCK
0x10C0010C = Unlocks PERCFG register accesses.
Any write to the PERCFG register will automatically relock the register. In order to avoid the unnecessary
overhead of multiple unlock/enable sequences, all peripherals should be enabled with a single write to the
PERCFG register with the necessary enable bits set.
Prior to waiting 128 CPU cycles, the PERCFG register should be read. There is no direct correlation between
the CPU issuing a write to the PERCFG register and the write actually occurring. Reading the PERCFG
register after the write is issued forces the CPU to wait for the write to the PERCFG register to occur.
Once a peripheral is enabled, the DSP (or other peripherals such as the HPI) must wait a minimum of 128 CPU
cycles before accessing the enabled peripheral. The user must ensure that no accesses are performed to a
peripheral while it is disabled.
In addition to the normal usage, the PCFGLOCK register can be used to override the power saver settings
specified in the PERCFG register. When the power saver feature is disabled (PCFGLOCK written with
0xC0100C01), all peripherals controlled by PERCFG are enabled. If the power saver is returned to normal
operation (PCFGLOCK written with 0x0C01 C010), then the peripherals return to the operating condition
specified by PERCFG. Turning off the power saver settings will add a worst-case 50 mW of power to the overall
DSP power consumption.
Note: overriding the settings of the PERCFG register will not cause a conflict on the multiplexed pins. For
example, with the HPI and McASP1 peripherals, the HPI will still have control over the multiplexed pins
provided the TOUT0/HPI_EN
pin was “0” at reset.

3.5 Device Status Register Description
The device status register depicts the status of the device peripheral selection. Once set, these bits will remain
set until a device reset; therefore, these bits should be masked when reading the DEVSTA T register since their

3.7 Multiplexed Pins
Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. Some
of these pins are configured by software, and the others are configured by external pullup/pulldown resistors
only at reset. Those muxed pins that are configured by software should not be programmed to switch
functionalities during run-time. Those muxed pins that are configured by external pullup/pulldown resistors
are mutually exclusive; only one peripheral has primary control of the function of these pins after reset.
Table 3−8 identifies the multiplexed pins on the C6418 device; shows the default (primary) function and the
default settings after reset; and describes the pins, registers, etc. necessary to configure specific multiplexed
functions.

3.8 Debugging Considerations
It is recommended that external connections be provided to device configuration pins, including
TOUT1/LENDIAN, AEA[22:19], TOUT0/HPI_EN
, CLKINSEL, and OSC_DIS. Although internal
pullup/pulldown resistors exist on these pins, providing external connectivity adds convenience to the user
in debugging and flexibility in switching operating modes.
Note: If a configuration pin must be routed out from the device, the internal pullup/pulldown (IPU/IPD) resistor
should not be relied upon. TI recommends the use of an external pullup/pulldown resistor.

3.11 Development Support
In case the customer would like to develop their own features and software on the TMS320C6418 device, TI
offers an extensive line of development tools for the TMS320C6000 DSP platform, including tools to
evaluate the performance of the processors, generate code, develop algorithm implementations, and fully
integrate and debug software and hardware modules. The tool’s support documentation is electronically
available within the Code Composer Studio Integrated Development Environment (IDE).
The following products support development of C6000 DSP-based applications:
Software Development Tools:
Code Composer Studio Integrated Development Environment (IDE): including Editor
C/C++/Assembly Code Generation, and Debug plus additional development tools
Scalable, Real-Time Foundation Software (DSP/BIOS), which provides the basic run-time target software
needed to support any DSP application.
Hardware Development Tools:
Extended Development System (XDS) Emulator (supports C6000 DSP multiprocessor system debug)
EVM (Evaluation Module)
For a complete listing of development-support tools for the TMS320C6000 DSP platform, visit the Texas
Instruments web site on the Worldwide Web at http://www.ti.com uniform resource locator (URL). For
information on pricing and availability, contact the nearest TI field sales office or authorized distributor.

3.12 Device Support
3.12.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP
devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or T MS
(e.g., TMS320C6412GDK600). Texas Instruments recommends two of three possible prefix designators for
its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
TMX Experimental device that is not necessarily representative of the final device’s electrical
specifications.
TMP Final silicon die that conforms to the device’s electrical specifications but has not completed quality
and reliability verification.
TMS Fully qualified production device.
Support tool development evolutionary flow:
TMDX Development-support product that has not yet completed Texas Instruments internal qualification
testing.
TMDS Fully qualified development-support product.
TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer:
“Developmental product is intended for internal evaluation purposes.”
TMS devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI’s standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production system
because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package
type (for example, GTS), the temperature range (for example, “A” is the extended commercial temperature
range), and the device speed range in megahertz (for example, -500 is 500 MHz). Figure 3−7 provides a
legend for reading the complete device name for any TMS320C6000 DSP platform member.
The ZTS package, like the GTS package, is a 288-ball plastic BGA only with Pb-free balls. For device part
numbers and further ordering information for TMS320C6418 in the GTS and ZTS package types, see the TI
website (http://www.ti.com) or contact your TI sales representative.

Peripherals Detailed Description (Device-Specific)
4 Peripherals Detailed Description (Device-Specific)
4.1 Clock PLL and Oscillator
Most of the internal C64x DSP clocks are generated from a single source through the CLKIN pin. This source
clock either drives the PLL, which multiplies the source clock frequency to generate the internal CPU clock,
or bypasses the PLL to become the internal CPU clock.
To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Figure 4−1
shows the external PLL circuitry for either x1 (PLL bypass) or other PLL multiply modes.
To minimize the clock jitter, a single clean power supply should power both the C64x DSP device and the
external clock oscillator circuit. The minimum CLKIN rise and fall times should also be observed. For the input
clock timing requirements, see the input and output clocks electricals section.
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock source
must meet the DSP requirements in this data sheet (see the electrical characteristics over recommended
ranges of supply voltage and operating case temperature table and the input and output clocks electricals
section).

Do not connect any of these nodes to board power or ground if the oscillator is used. They are internally connected for proper operation.
If CLKIN is being used instead of the oscillator, then OSCVDD and OSCVSS may either be left open, or OSCVDD may be tied to CVDD and
OSCVSS may be tied to ground.
NOTES: A. Place all PLL external components (C1, C2, and the EMI Filter) as close to the C6000 DSP device as possible. For the best
performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or
components other than the ones shown.
B. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (C1, C2, and the EMI
Filter).
C. The 3.3-V supply for the EMI filter must be from the same 3.3-V power plane supplying the I/O voltage, DVDD.
D. EMI filter manufacturer TDK part number ACF451832-333, -223, -153, -103. Panasonic part number EXCCET103U.

For the lowest jitter on the oscillator circuit, it is recommended that a pair of 470-pF capacitors be connected
between isolated (not directly connected to the board supply) OSCV
and OSCVSS pins. This helps to cancel

4.2 Host-Port Interface (HPI) Peripheral
The TMS320C6418 device includes a user-configurable 16-bit or 32-bit Host-port interface (HPI16/HPI32).
On the C6418 device the HPI peripheral pins are muxed with the McASP1 and GP0 peripheral pins. By default,
the HPI peripheral pin functions are enabled. For more detailed information on the C6418 device pin muxing,
see the Device Configurations section of this data sheet.
The HPI peripheral can be disabled or enabled at reset through the HPI enable function of the TOUT0/HPI_EN
pin. The HPI is enabled when the TOUT0/HPI_EN pin is sampled low at reset and it is disabled if the pin is
sample high at reset. The TOUT0/HPI_EN
However, the HPI can be disabled via an external pullup resistor or by having an external device such as an
FPGA/CPLD drive that pin high at reset. In the latter case, the external device should ensure it has stopped
driving this pin to avoid contention. The HPI enable function can only be set a reset and cannot be changed
via software.
The HD5 pin controls the HPI_WIDTH, allowing the user to configure the HPI as a 16-bit or 32-bit peripheral.
For more details on HPI peripheral configuration and the associated pins, see the Device Configurations
section of this data sheet.

Multichannel Audio Serial Port (McASP) Peripheral
4.3 Multichannel Audio Serial Port (McASP) Peripheral
The TMS320C6418 device includes two multichannel audio serial port (McASP) interface peripheral
(McASP0 and McASP1). On the C6418 device the McASP1 peripheral pins are muxed with the HPI peripheral
pins. By default, the HPI peripheral pin functions are enabled. For the C6418 device McASP1 is a standalone
peripheral, not muxed. For more detailed information on the C6418 device pin muxing, see the Device
Configurations section of this data sheet.
The McASP is a serial port optimized for the needs of multichannel audio applications.
The McASP consists of a transmit and receive section. These sections can operate completely independently
with different data formats, separate master clocks, bit clocks, and frame syncs or alternatively, the transmit
and receive sections may be synchronized. The McASP module also includes a pool of 16 shift registers that
may be configured to operate as either transmit data, receive data, or general-purpose I/O (GPIO).
The transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM) synchronous
serial format or in a digital audio interface (DIT) format where the bit stream is encoded for S/PDIF, AES-3,
IEC-60958, CP-430 transmission. The receive section of the McASP supports the TDM synchronous serial
format.
The McASP can support one transmit data format (either a TDM format or DIT format) and one receive format
at a time. All transmit shift registers use the same format and all receive shift registers use the same format.
However, the transmit and receive formats need not be the same.
Both the transmit and receive sections of the McASP also support burst mode which is useful for non-audio
data (for example, passing control information between two DSPs).
The McASP peripheral has additional capability for flexible clock generation, and error detection/handling, as
well as error management.
For more detailed information on and the functionality of the McASP peripheral, see the TMS320C6000 DSP
Multichannel Audio Serial Port (McASP) Reference Guide (literature number SPRU041).
4.3.1 McASP Block Diagram
Figure 4−2 illustrates the major blocks along with external signals of the TMS320C6418 McASP peripheral;
and shows the 6 serial data [AXRx] pins. The McASP also includes full general-purpose I/O (GPIO) control,
so any pins not needed for serial transfers can be used for general-purpose I/O.

I2C
4.4 I2C
The TMS320C6418 device includes two I2C peripheral modules (I2C0 and I2C1). NOTE: when using the I2C
modules (any mode), ensure there are external pullup resistors on the SDAx and SCLx pins.
One of the I2C modules on the TMS320C6418 may be used by the DSP to control local peripherals ICs (DACs,
ADCs, etc.) while the other module may be used to communicate with other controllers in a system or to
implement a user interface.
The I2Cx port supports:
• Compatible with Philips I2C Specification Revision 2.1 (January 2000)
• Fast Mode up to 400 Kbps (no fail-safe I/O buffers)
• Noise Filter to remove noise 50 ns or less
• 7- and 10-Bit Device Addressing Modes
• Multi-Master (Transmit/Receive) and Slave (Transmit/Receive) Functionality
• Events: DMA, Interrupt, or Polling
• Slew-Rate Limited Open-Drain Output Buffers
• General-purpose input and output (GPIO) functionality for I2C pins
For more detailed information on C6418 I2C additional features, such as GPIO capability, etc., see the
TMS320C6000 DSP Inter−Integrated Circuit (I2C) Module Reference Guide (literature number SPRU175)

4.5 Viterbi-Decoder Coprocessor (VCP)
The C6418 device has a high-performance embedded coprocessor [Viterbi-Decoder Coprocessor (VCP) that
significantly speeds up channel-decoding operations on-chip. The VCP operating at CPU clock divided-by-4
can decode over 500 7.95-Kbps adaptive multi-rate (AMR) [K = 9, R = 1/3] voice channels. The VCP supports
constraint lengths K = 5, 6, 7, 8, and 9, rates R = 1/2, 1/3, and 1/4, and flexible polynomials, while generating
hard decisions or soft decisions. Communications between the VCP and the CPU are carried out through the
EDMA controller.
For more detailed information on the VCP, see the TMS320C64x DSP Viterbi-Decoder Coprocessor
Reference Guide (literature number SPRU533).
4.6 General-Purpose Input/Output (GPIO)
On the C6418 device the GPIO peripheral pins GP0[15:9] are muxed with the HPI peripheral pins HD[15:9],
respectively . B y default, the HPI peripheral pin functions are enabled [T OUT0/HPI_EN

General-Purpose Input/Output (GPIO)
To use the GP0[15:0] software-configurable GPIO pins, the GPxEN bits in the GP Enable (GPEN) Register
and the GPxDIR bits in the GP Direction (GPDIR) Register must be properly configured.
GPxEN = 1 GP[x] pin is enabled
GPxDIR = 0 GP[x] pin is an input
GPxDIR = 1 GP[x] pin is an output
where “x” represents one of the 15 through 0 GPIO pins
Figure 4−4 shows the GPIO enable bits in the GPEN register for the C6418 device. To use any of the GPx
pins as general-purpose input/output functions, the corresponding GPxEN bit must be set to “1” (enabled).
Default values are device-specific, so refer to Figure 4−4 for the C6418 default configuration.

When entering PD2 and PD3, all functional I/O remains in the previous state. However, for peripherals which are asynchronous in nature or

Power-Supply Sequencing
4.7.2 C64x Power-Down Mode with an Emulator
If user power-down modes are programmed, and an emulator is attached, the modes will be masked to allow
the emulator access to the system. This condition prevails until the emulator is reset or the cable is removed
from the header . If power measurements are to be performed when in a power-down mode, the emulator cable
should be removed.
When the DSP is in power-down mode PD2 or PD3, emulation logic will force any emulation execution
command (such as Step or Run) to spin in IDLE. For this reason, PC writes (such as loading code) will fail.
A DSP reset will be required to get the DSP out of PD2/PD3.
4.8 Power-Supply Sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However,
systems should be designed to ensure that neither supply is powered up for extended periods of time
(>1 second) if the other supply is below the proper operating voltage.
4.8.1 Power-Supply Design Considerations
A dual-power supply with simultaneous sequencing can be used to eliminate the delay between core and I/O
power up. A Schottky diode can also be used to tie the core rail to the I/O rail (see Figure 4−8).

Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize
inductance and resistance in the power delivery path. Additionally, when designing for high-performance
applications utilizing the C6000 platform of DSPs, the PC board should include separate power planes for
core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.

August 2004 − Revised January 2006SPRS241D
4.9 Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as
possible close to the DSP. Assuming 0603 caps, the user should be able to fit a total of 60 caps, 30 for the
core supply and 30 for the I/O supply. These caps need to be close to the DSP power pins, no more than
1.25 cm maximum distance to be effective. Physically smaller caps, such as 0402, are better because of their
lower parasitic inductance. Proper capacitance values are also important. Small bypass caps (near 560 pF)
should be closest to the power pins. Medium bypass caps (220 nF or as large as can be obtained in a small
package) should be next closest. TI recommends no less than 8 small and 8 medium caps per supply (32 total)
be placed immediately next to the BGA vias, using the “interior” BGA space and at least the corners of the
“exterior”.
Eight larger caps (4 for each supply) can be placed further away for bulk decoupling. Large bulk caps (on the
order of 100 µF) should be furthest away (but still as close as possible). No less than 4 large caps per supply
(8 total) should be placed outside of the BGA.
Any cap selection needs to be evaluated from a yield/manufacturing point-of-view. As with the selection of any
component, verification of capacitor availability over the product’s production lifetime should be considered.
4.10 Peripheral Power-Down Operation
The C6418 device can be powered down in two ways:
• Power-down due to software configuration − relates to the default state of the peripheral configuration bits
in the PERCFG register.
• Power-down during run-time via software configuration
Power-Supply Decoupling
On the C6418 device, the HPI, McASP1, and GP0 peripherals pin muxing is controlled (selected) at the pin
level during chip reset (e.g., HPI_EN and HD5 pins). If McASP1 pin muxing is selected, then the McASP1
peripheral configuration register bit must be configured properly to enable the McASP1 peripheral.
The McASP1, McASP0, I2C1, and I2C0 peripheral functions are selected via the peripheral configuration
(PERCFG) register bits.
For more detailed information on the peripheral configuration pins and the PERCFG register bits, see the
Device Configurations section of this document.

4.12 EMIF Device Speed
The rated EMIF speed of these devices only applies to the SDRAM interface when in a system that meets the
following requirements:
• 1 chip-enable (CE) space (maximum of 2 chips) of SDRAM connected to EMIF
• up to 1 CE space of buffers connected to EMIF
• EMIF trace lengths between 1 and 3 inches
• 166-MHz SDRAM for 133-MHz operation
• 143-MHz SDRAM for 100-MHz operation
Other configurations may be possible, but timing analysis must be done to verify all AC timings are met.
Verification of AC timings is mandatory when using configurations other than those specified above. TI
recommends utilizing I/O buffer information specification (IBIS) to analyze all AC timings.
To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models
for Timing Analysis application report (literature number SPRA839).
To maintain signal integrity, serial termination resistors should be inserted into all EMIF output signal lines (see
the Terminal Functions table for the EMIF output signals).
For more detailed information on the C6418 EMIF peripheral, see the TMS320C6000 DSP External Memory
Interface (EMIF) Reference Guide (literature number SPRU266).

4.13 Bootmode
The C6418 device resets using the active-low signal RESET. While RESET is low, the device is held in reset
and is initialized to the prescribed reset state. Refer to reset timing for reset timing characteristics and states
of device pins during reset. The release of RESET
configuration and boot mode.
The C6418 has three types of boot modes:
• Host boot
Bootmode
starts the processor running with the prescribed device
If host boot is selected, upon release of RESET
, the CPU is internally “stalled” while the remainder of the
device is released. During this period, an external host can initialize the CPU’s memory space as
necessary through the host interface, including internal configuration registers, such as those that control
the EMIF or other peripherals. For the C6418 device, the HPI peripheral is used for host boot providing the
TOUT0/HPI_EN
pin is low, enabling the HPI peripheral [default]. Once the host is finished with all
necessary initialization, it must set the DSPINT bit in the HPIC register to complete the boot process. This
transition causes the boot configuration logic to bring the CPU out of the “stalled” state. The CPU then
begins execution from address 0. The DSPINT condition is not latched by the CPU, because it occurs
while the CPU is still internally “stalled”. Also, DSPINT brings the CPU out of the “stalled” state only if the
host boot process is selected. All memory may be written to and read by the host. This allows for the host to
verify what it sends to the DSP if required. After the CPU is out of the “stalled” state, the CPU needs to clear
the DSPINT, otherwise, no more DSPINTs can be received.
• EMIF boot (using default ROM timings)
Upon the release of RESET
, the 1K-Byte ROM code located in the beginning of CE1 is copied to address 0
by the EDMA using the default ROM timings, while the CPU is internally “stalled”. The data should be
stored in the endian format that the system is using. In this case, the EMIF automatically assembles
consecutive 8-bit bytes to form the 32-bit instruction words to be copied. The transfer is automatically done
by the EDMA as a single-frame block transfer from the ROM to address 0. After completion of the block
transfer, the CPU is released from the “stalled” state and starts running from address 0.
• No boot
With no boot, the CPU begins direct execution from the memory located at address 0. Note: operation is
undefined if invalid code is located at address 0.
4.14 Reset
A hardware reset (RESET) is required to place the DSP into a known good state out of power-up. The RESET
signal can be asserted (pulled low) prior to ramping the core and I/O voltages or after the core and I/O voltages
have reached their proper operating conditions. As a best practice, reset should be held low during power-up.
Prior to deasserting RESET

Future variants of the C64x DSPs may operate at voltages ranging from 0.9 V to 1.4 V to provide a range of system power/performance options.
TI highly recommends that users design-in a supply that can handle multiple voltages within this range (i.e., 1.2 V, 1.25 V, 1.3 V, 1.35 V, 1.4 V
with ± 3% tolerances) by implementing simple board changes such as reference resistor values or input pin configuration modifications. Examples
of such supplies include the PT4660, PT5500, PT5520, PT6440, and PT6930 series from Power Trends, a subsidiary of Texas Instruments. Not
incorporating a flexible supply may limit the system’s ability to easily adapt to future versions of C64x devices.

6.4 Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data sheet do not include delays by board routings. As a good
board design practice, such delays must always be taken into account. Timing values may be adjusted by
increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification
(IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate
timing analysis for a given system, see the Using IBIS Models for Timing Analysis application report (literature
number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing
differences.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device
and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time
margin, but also tends to improve the input hold time margins (see Table 6−1 and Figure 6−6).
Figure 6−6 represents a general transfer between the DSP and an external device. The figure also represents
board route delays and how they are perceived by the DSP and the external device.

The reference points for the rise and fall transitions are measured at VIL MAX and VIH MIN.
§
E = the EMIF input clock (AECLKIN, CPU/4 clock, or CPU/6 clock) period in ns.
¶
Minimum AECLKIN cycle times must be met, even when AECLKIN is generated by an internal clock source. Minimum AECLKIN times are based
on internal logic speed; the maximum useable speed of the EMIF may be lower due to AC timing requirements. 133-MHz and 100-MHz operations
are achievable if the requirements of the EMIF Device Speed section are met.
