Figure 2. ADSP-21062 System
Data Register File
A general purpose data register file is used for transferring data
between the computation units and the data buses, and for
storing intermediate results. This 10-port, 32-register (16 primary, 16 secondary) register file, combined with the ADSP21000 Harvard architecture, allows unconstrained data flow
between computation units and internal memory.
Single-Cycle Fetch of Instruction and Two Operands
The ADSP-21062 features an enhanced Harvard architecture in
which the data memory (DM) bus transfers data and the program memory (PM) bus transfers both instructions and data
(see Figure 1). With its separate program and data memory
buses and on-chip instruction cache, the processor can simultaneously fetch two operands and an instruction (from the cache),
all in a single cycle.
Instruction Cache
The ADSP-21062 includes an on-chip instruction cache that
enables three-bus operation for fetching an instruction and two
data values. The cache is selective—only the instructions whose
fetches conflict with PM bus data accesses are cached. This
allows full-speed execution of core, looped operations such as
digital filter multiply-accumulates and FFT butterfly processing.
Data Address Generators with Hardware Circular Buffers
The ADSP-21062’s two data address generators (DAGs) implement circular data buffers in hardware. Circular buffers allow
efficient programming of delay lines and other data structures
required in digital signal processing, and are commonly used in
digital filters and Fourier transforms. The two DAGs of the
ADSP-21062 contain sufficient registers to allow the creation of
up to 32 circular buffers (16 primary register sets, 16 secondary).
The DAGs automatically handle address pointer wraparound,
reducing overhead, increasing performance and simplifying
implementation. Circular buffers can start and end at any
memory location.
Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations, for concise programming. For example, the ADSP21062 can conditionally execute a multiply, an add, a subtract
and a branch, all in a single instruction.
ADSP-21062/ADSP-21062L FEATURES
Augmenting the ADSP-21000 family core, the ADSP-21062
adds the following architectural features:
Dual-Ported On-Chip Memory
The ADSP-21062 contains two megabits of on-chip SRAM,
organized as two blocks of 1 Mbits each, which can be configured for different combinations of code and data storage. Each
memory block is dual-ported for single-cycle, independent accesses by the core processor and I/O processor or DMA controller. The dual-ported memory and separate on-chip buses allow
two data transfers from the core and one from I/O, all in a single
cycle.
On the ADSP-21062, the memory can be configured as a maximum of 64K words of 32-bit data, 128K words of 16-bit data,
40K words of 48-bit instructions (or 40-bit data), or combinations of different word sizes up to two megabits. All of the
memory can be accessed as 16-bit, 32-bit or 48-bit words.
A 16-bit floating-point storage format is supported, which effectively doubles the amount of data that may be stored on-chip.
Conversion between the 32-bit floating-point and 16-bit floatingpoint formats is done in a single instruction.
While each memory block can store combinations of code and
data, accesses are most efficient when one block stores data,
using the DM bus for transfers, and the other block stores
instructions and data, using the PM bus for transfers. Using the
DM bus and PM bus in this way, with one dedicated to each
memory block, assures single-cycle execution with two data
transfers. In this case, the instruction must be available in the
cache. Single-cycle execution is also maintained when one of the
data operands is transferred to or from off-chip, via the ADSP21062’s external port.
ADSP-21062/ADSP-21062L
–5–
REV. C
include interrupt generation upon completion of DMA transfers and DMA chaining for automatic linked DMA transfers.
Serial Ports
The ADSP-21062 features two synchronous serial ports that
provide an inexpensive interface to a wide variety of digital and
mixed-signal peripheral devices. The serial ports can operate at
the full clock rate of the processor, providing each with a maximum data rate of 40 Mbit/s. Independent transmit and receive
functions provide greater flexibility for serial communications.
Serial port data can be automatically transferred to and from
on-chip memory via DMA. Each of the serial ports offers TDM
multichannel mode.
The serial ports can operate with little-endian or big-endian
transmission formats, with word lengths selectable from 3 bits to
32 bits. They offer selectable synchronization and transmit
modes as well as optional µ-law or A-law companding. Serial
port clocks and frame syncs can be internally or externally
generated.
Multiprocessing
The ADSP-21062 offers powerful features tailored to multiprocessor DSP systems. The unified address space (see
Figure 4) allows direct interprocessor accesses of each ADSP21062’s internal memory. Distributed bus arbitration logic is
included on-chip for simple, glueless connection of systems
containing up to six ADSP-21062s and a host processor. Master
processor changeover incurs only one cycle of overhead. Bus
arbitration is selectable as either fixed or rotating priority. Bus lock
allows indivisible read-modify-write sequences for semaphores. A
vector interrupt is provided for interprocessor commands. Maximum throughput for interprocessor data transfer is 240 Mbytes/s
over the link ports or external port. Broadcast writes allow simultaneous transmission of data to all ADSP-21062s and can be used
to implement reflective semaphores.
Link Ports
The ADSP-21062 features six 4-bit link ports that provide additional I/O capabilities. The link ports can be clocked twice per
cycle, allowing each to transfer eight bits of data per cycle. Link
port I/O is especially useful for point-to-point interprocessor
communication in multiprocessing systems.
The link ports can operate independently and simultaneously,
with a maximum data throughput of 240 Mbytes/s. Link port
data is packed into 32- or 48-bit words, and can be directly read
by the core processor or DMA-transferred to on-chip memory.
Each link port has its own double-buffered input and output
registers. Clock/acknowledge handshaking controls link port
transfers. Transfers are programmable as either transmit or
receive.
Program Booting
The internal memory of the ADSP-21062 can be booted at
system power-up from either an 8-bit EPROM, a host processor, or through one of the link ports. Selection of the boot
source is controlled by the BMS (Boot Memory Select),
EBOOT (EPROM Boot), and LBOOT (Link/Host Boot) pins.
32-bit and 16-bit host processors can be used for booting.
Off-Chip Memory and Peripherals Interface
The ADSP-21062’s external port provides the processor’s interface to off-chip memory and peripherals. The 4-gigaword offchip address space is included in the ADSP-21062’s unified
address space. The separate on-chip buses—for PM addresses,
PM data, DM addresses, DM data, I/O addresses and I/O
data—are multiplexed at the external port to create an external
system bus with a single 32-bit address bus and a single 48-bit
(or 32-bit) data bus.
Addressing of external memory devices is facilitated by on-chip
decoding of high-order address lines to generate memory bank
select signals. Separate control lines are also generated for simplified addressing of page-mode DRAM. The ADSP-21062
provides programmable memory wait states and external
memory acknowledge controls to allow interfacing to DRAM
and peripherals with variable access, hold and disable time
requirements.
Host Processor Interface
The ADSP-21062’s host interface allows easy connection to
standard microprocessor buses, both 16-bit and 32-bit, with
little additional hardware required. Asynchronous transfers at
speeds up to the full clock rate of the processor are supported.
The host interface is accessed through the ADSP-21062’s external port and is memory-mapped into the unified address space.
Four channels of DMA are available for the host interface; code
and data transfers are accomplished with low software overhead.
The host processor requests the ADSP-21062’s external bus
with the host bus request (HBR), host bus grant (HBG), and
ready (REDY) signals. The host can directly read and write the
internal memory of the ADSP-21062, and can access the DMA
channel setup and mailbox registers. Vector interrupt support is
provided for efficient execution of host commands.
DMA Controller
The ADSP-21062’s on-chip DMA controller allows zerooverhead data transfers without processor intervention. The
DMA controller operates independently and invisibly to the
processor core, allowing DMA operations to occur while the
core is simultaneously executing its program instructions.
DMA transfers can occur between the ADSP-21062’s internal
memory and either external memory, external peripherals or a
host processor. DMA transfers can also occur between the
ADSP-21062’s internal memory and its serial ports or link
ports. DMA transfers between external memory and external
peripheral devices are another option. External bus packing to
16-, 32-, or 48-bit words is performed during DMA transfers.
Ten channels of DMA are available on the ADSP-21062—two
via the link ports, four via the serial ports, and four via the
processor’s external port (for either host processor, other
ADSP-21062s, memory or I/O transfers). Four additional
link port DMA channels are shared with serial port 1 and the
external port. Programs can be downloaded to the ADSP21062 using DMA transfers. Asynchronous off-chip peripherals can control two DMA channels using DMA Request/
Grant lines (DMAR1-2, DMAG1-2 ). Other DMA features

DEVELOPMENT TOOLS
The ADSP-21062 is supported with a complete set of software
and hardware development tools, including an EZ-ICE
In-
Circuit Emulator, EZ-LAB
®
development board, EZ-KIT, and
development software. The EZ-LAB contains an evaluation board
with an ADSP-21062 (5 V) processor and provides a serial connection to your PC. The SHARC
EZ-KIT combines the ADSP21000 Family Development Software for the PC and the
EZ-LAB
ADSP-21062’s Development Board in one package.
The EZ-KIT contains in addition to the EZ-LAB development
board, an optimizing compiler, assembler, instruction level simulator, run-time libraries, diagnostic utilities and a complete set
of example programs.
The same EZ-ICE hardware can be used for the ADSP-21060/
ADSP-21061, to fully emulate the ADSP-21062, with the exception of displaying and modifying the two new SPORTS registers.
The emulator will not display these two registers, but your
code can use them.
Analog Devices’ ADSP-21000 Family Development Software
includes an easy to use Assembler based on an algebraic syntax,
an Assembly Library/Librarian, a Linker, an Instruction-level
Simulator, an ANSI C optimizing Compiler, the CBug™ C
Source-Level Debugger, and a C Runtime Library including
DSP and mathematical functions. The Optimizing Compiler
includes Numerical C extensions based on the work of the
ANSI Numerical C Extensions Group. Numerical C provides
extensions to the C language for array selection, vector math
operations, complex data types, circular pointers, and variably
dimensioned arrays. The ADSP-21000 Family Development
Software is available for both the PC and Sun platforms.
The ADSP-21062 EZ-ICE
Emulator uses the IEEE 1149.1
JTAG test access port of the ADSP-21062 processor to monitor
and control the target board processor during emulation. The
EZ-ICE
provides full-speed emulation, allowing inspection and
modification of memory, registers, and processor stacks. Nonintrusive in-circuit emulation is assured by the use of the processor’s
JTAG interface—the emulator does not affect target system
loading or timing.
Further details and ordering information are available in the
ADSP-21000 Family Hardware & Software Development Tools
data sheet (ADDS-210xx-TOOLS). This data sheet can be
requested from any Analog Devices sales office, distributor or
the Literature Center.
In addition to the software and hardware development tools
available from Analog Devices, third parties provide a wide
range of tools supporting the SHARC processor family. Hardware tools include SHARC
PC plug-in cards, multiprocessor
SHARC
VME boards, and daughter card modules with multiple
SHARCs and additional memory. These modules are based on
the SHARCPAC™
module specification. Third party software
tools include an Ada compiler, DSP libraries, operating systems,
and block diagram design tools.

PIN FUNCTION DESCRIPTIONS
ADSP-21062 pin definitions are listed below. All pins are identical on the ADSP-21062 and ADSP-21062L. Inputs identified
as synchronous (S) must meet timing requirements with respect
to CLKIN (or with respect to TCK for TMS, TDI). Inputs
identified as asynchronous (A) can be asserted asynchronously
to CLKIN (or to TCK for TRST).
Unused inputs should be tied or pulled to VDD or GND,
except for ADDR
31-0
, DATA
47-0
, FLAG
3-0
, SW, and inputs that
have internal pull-up or pull-down resistors (CPA, ACK, DTx,
DRx, TCLKx, RCLKx, LxDAT3-0, LxCLK, LxACK, TMS
and TDI)—these pins can be left floating. These pins have a
logic-level hold circuit that prevents the input from floating
internally.
A = Asynchronous G = Ground I = Input
O = Output P = Power Supply S = Synchronous
(A/D) = Active Drive (O/D) = Open Drain
T = Three-State (when SBTS is asserted, or when the
ADSP-21062 is a bus slave)
Pin Type Function
ADDR
31-0
I/O/T External Bus Address. The ADSP-21062 outputs addresses for external memory and peripherals on
these pins. In a multiprocessor system the bus master outputs addresses for read/writes of the internal
memory or IOP registers of other ADSP-21062s. The ADSP-21062 inputs addresses when a host
processor or multiprocessing bus master is reading or writing its internal memory or IOP registers.
DATA
47-0
I/O/T External Bus Data. The ADSP-21062 inputs and outputs data and instructions on these pins. 32-bit
single-precision floating-point data and 32-bit fixed-point data is transferred over bits 47–16 of the
bus. 40-bit extended-precision floating-point data is transferred over bits 47–8 of the bus. 16-bit short
word data is transferred over bits 31–16 of the bus. In PROM boot mode, 8-bit data is transferred over
bits 23–16. Pull-up resistors on unused DATA pins are not necessary.
MS
3-0
O/T Memory Select Lines. These lines are asserted (low) as chip selects for the corresponding banks of
external memory. Memory bank size must be defined in the ADSP-21062’s system control register
(SYSCON). The MS
3-0
lines are decoded memory address lines that change at the same time as the
other address lines. When no external memory access is occurring the MS
3-0
lines are inactive; they are
active however when a conditional memory access instruction is executed, whether or not the condition is true. MS
0
can be used with the PAGE signal to implement a bank of DRAM memory (Bank 0).
In a multiprocessing system the MS
3-0
lines are output by the bus master.
RD I/O/T Memory Read Strobe. This pin is asserted (low) when the ADSP-21062 reads from external
memory devices or from the internal memory of other ADSP-21062s. External devices (including
other ADSP-21062s) must assert RD to read from the ADSP-21062’s internal memory. In a multiprocessing system RD is output by the bus master and is input by all other ADSP-21062s.
WR I/O/T Memory Write Strobe. This pin is asserted (low) when the ADSP-21062 writes to external memory
devices or to the internal memory of other ADSP-21062s. External devices must assert WR to write to
the ADSP-21062’s internal memory. In a multiprocessing system WR is output by the bus master and
is input by all other ADSP-21062s.
PAGE O/T DRAM Page Boundary. The ADSP-21062 asserts this pin to signal that an external DRAM page
boundary has been crossed. DRAM page size must be defined in the ADSP-21062’s memory control
register (WAIT). DRAM can only be implemented in external memory Bank 0; the PAGE signal can
only be activated for Bank 0 accesses. In a multiprocessing system PAGE is output by the bus master.
ADRCLK O/T Clock Output Reference. In a multiprocessing system ADRCLK is output by the bus master.
SW I/O/T Synchronous Write Select. This signal is used to interface the ADSP-21062 to synchronous
memory devices (including other ADSP-21062s). The ADSP-21062 asserts SW (low) to provide an
early indication of an impending write cycle, which can be aborted if WR is not later asserted (e.g., in
a conditional write instruction). In a multiprocessing system, SW is output by the bus master and is
input by all other ADSP-21062s to determine if the multiprocessor memory access is a read or write.
SW is asserted at the same time as the address output. A host processor using synchronous writes
must assert this pin when writing to the ADSP-21062(s).
ACK I/O/S Memory Acknowledge. External devices can deassert ACK (low) to add wait states to an external
memory access. ACK is used by I/O devices, memory controllers, or other peripherals to hold off
completion of an external memory access. The ADSP-21062 deasserts ACK as an output to add wait
states to a synchronous access of its internal memory. In a multiprocessing system, a slave ADSP21062 deasserts the bus master’s ACK input to add wait state(s) to an access of its internal memory.
The bus master has a keeper latch on its ACK pin that maintains the input at the level to which it
was last driven.
ADSP-21062/ADSP-21062L
–9–
REV. C
Pin Type Function
SBTS I/S Suspend Bus Three-State. External devices can assert SBTS (low) to place the external bus address,
data, selects and strobes in a high impedance state for the following cycle. If the ADSP-21062
attempts to access external memory while SBTS is asserted, the processor will halt and the memory
access will not be completed until SBTS is deasserted. SBTS should only be used to recover from host
processor/ADSP-21062 deadlock, or used with a DRAM controller.
IRQ
2-0
I/A Interrupt Request Lines. May be either edge-triggered or level-sensitive.
FLAG
3-0
I/O/A Flag Pins. Each is configured via control bits as either an input or output. As an input, they can be
tested as a condition. As an output, they can be used to signal external peripherals.
TIMEXP O Timer Expired. Asserted for four cycles when the timer is enabled and TCOUNT decrements to
zero.
HBR I/A Host Bus Request. This pin must be asserted by a host processor to request control of the
ADSP-21062’s external bus. When HBR is asserted in a multiprocessing system, the ADSP-21062
that is bus master will relinquish the bus and assert HBG. To relinquish the bus, the ADSP-21062
places the address, data, select and strobe lines in a high impedance state. HBR has priority over all
ADSP-21062 bus requests (BR
6-1
) in a multiprocessing system.
HBG I/O Host Bus Grant. Acknowledges an HBR bus request, indicating that the host processor may take
control of the external bus. HBG is asserted (held low) by the ADSP-21062 until HBR is released. In
a multiprocessing system, HBG is output by the ADSP-21062 bus master and is monitored by all others.
CS I/A Chip Select. Asserted by host processor to select the ADSP-21062.
REDY (O/D) O Host Bus Acknowledge. The ADSP-21062 deasserts REDY (low) to add wait states to an asynchro-
nous access of its internal memory or IOP registers by a host. This pin is an open drain output (O/D)
by default; it can be programmed in the ADREDY bit of the SYSCON register to be active drive
(A/D). REDY will only be output if the CS and HBR inputs are asserted.
DMAR1 I/A DMA Request 1 (DMA Channel 7).
DMAR2 I/A DMA Request 2 (DMA Channel 8).
DMAG1 O/T DMA Grant 1 (DMA Channel 7).
DMAG2 O/T DMA Grant 2 (DMA Channel 8).
BR
6-1
I/O/S Multiprocessing Bus Requests. Used by multiprocessing ADSP-21062s to arbitrate for bus master-
ship. An ADSP-21062 only drives its own BRx line (corresponding to the value of its ID
2-0
inputs) and
monitors all others. In a multiprocessor system with less than six ADSP-21062s, the unused BRx pins
should be pulled high; the processor’s own BRx line must not be pulled high or low because it is an
output.
ID
2-0
I Multiprocessing ID. Determines which multiprocessing bus request (BR1 – BR6) is used by ADSP-
21062. ID = 001 corresponds to BR1, ID = 010 corresponds to BR2, etc. ID = 000 in single-processor
systems. These lines are a system configuration selection which should be hardwired or changed at
reset only.
RPBA I/S Rotating Priority Bus Arbitration Select. When RPBA is high, rotating priority for multiprocessor
bus arbitration is selected. When RPBA is low, fixed priority is selected. This signal is a system configuration selection which must be set to the same value on every ADSP-21062. If the value of RPBA is
changed during system operation, it must be changed in the same CLKIN cycle on every ADSP-21062.
CPA (O/D) I/O Core Priority Access. Asserting its CPA pin allows the core processor of an ADSP-21062 bus slave
to interrupt background DMA transfers and gain access to the external bus. CPA is an open drain
output that is connected to all ADSP-21062s in the system. The CPA pin has an internal 5 kΩ pull-up
resistor. If core access priority is not required in a system, the CPA pin should be left unconnected.
DTx O Data Transmit (Serial Ports 0, 1). Each DT pin has a 50 kΩ internal pull-up resistor.
DRx I Data Receive (Serial Ports 0, 1). Each DR pin has a 50 kΩ internal pull-up resistor.
TCLKx I/O Transmit Clock (Serial Ports 0, 1). Each TCLK pin has a 50 kΩ internal pull-up resistor.
RCLKx I/O Receive Clock (Serial Ports 0, 1). Each RCLK pin has a 50 kΩ internal pull-up resistor.

LxACK I/O Link Port Acknowledge (Link Ports 0–5). Each LxACK pin has a 50 kΩ internal pull-down resistor
that is enabled or disabled by the LPDRD bit of the LCOM register.
EBOOT I EPROM Boot Select. When EBOOT is high, the ADSP-21062 is configured for booting from an 8-
bit EPROM. When EBOOT is low, the LBOOT and BMS inputs determine booting mode. See table
below. This signal is a system configuration selection that should be hardwired.
LBOOT I Link Boot. When LBOOT is high, the ADSP-21062 is configured for link port booting. When
LBOOT is low, the ADSP-21062 is configured for host processor booting or no booting. See table
below. This signal is a system configuration selection that should be hardwired.
BMS I/O/T* Boot Memory Select. Output: Used as chip select for boot EPROM devices (when EBOOT = 1,
LBOOT = 0). In a multiprocessor system, BMS is output by the bus master. Input: When low, indicates that no booting will occur and that ADSP-21062 will begin executing instructions from external
memory. See table below. This input is a system configuration selection that should be hardwired.
*Three-statable only in EPROM boot mode (when BMS is an output).

CLKIN I Clock In. External clock input to the ADSP-21062. The instruction cycle rate is equal to CLKIN.
CLKIN may not be halted, changed, or operated below the minimum specified frequency.
RESET I/A Processor Reset. Resets the ADSP-21062 to a known state and begins program execution at the
program memory location specified by the hardware reset vector address. This input must be asserted

TDI I/S Test Data Input (JTAG). Provides serial data for the boundary scan logic. TDI has a 20 kΩ internal
pull-up resistor.
TDO O Test Data Output (JTAG). Serial scan output of the boundary scan path.
TRST I/A Test Reset (JTAG). Resets the test state machine. TRST must be asserted (pulsed low) after power-
up or held low for proper operation of the ADSP-21062. TRST has a 20 kΩ internal pull-up resistor.
EMU O Emulation Status. Must be connected to the ADSP-21062 EZ-ICE

The 14-pin, 2-row pin strip header is keyed at the Pin 3 location —
Pin 3 must be removed from the header. The pins must be
0.025 inch square and at least 0.20 inch in length. Pin spacing
should be 0.1 × 0.1 inches. Pin strip headers are available from
vendors such as 3M, McKenzie, and Samtec.
The BTMS, BTCK, BTRST, and BTDI signals are provided so
that the test access port can also be used for board-level testing.
When the connector is not being used for emulation, place
jumpers between the BXXX pins and the XXX pins as shown in
Figure 5. If you are not going to use the test access port for
board testing, tie BTRST to GND and tie or pull up BTCK to
VDD. The TRST pin must be asserted after power-up (through
BTRST on the connector) or held low for proper operation of
the ADSP-2106x. None of the BXXX pins (Pins 5, 7, 9, 11) are
connected on the EZ-ICE probe.
The JTAG signals are terminated on the EZ-ICE probe as follows:
Signal Termination
TMS Driven through 22 Ω Resistor (16 mA Driver)
TCK Driven at 10 MHz through 22 Ω Resistor (16 mA
Driver)
TRST* Active Low Driven through 22 Ω Resistor (16 mA
Driver) (Pulled Up by On-Chip 20 kΩ Resistor)
TDI Driven by 22 Ω Resistor (16 mA Driver)
TDO One TTL Load, Split Termination (160/220)
CLKIN One TTL Load, Split Termination (160/220)
EMU Active Low 4.7 kΩ Pull-Up Resistor, One TTL Load
(Open-Drain Output from the DSP)
*TRST is driven low until the EZ-ICE probe is turned on by the emulator at
software start-up. After software start-up, TRST is driven high.
TARGET BOARD CONNECTOR FOR EZ-ICE PROBE
The ADSP-2106x EZ-ICE Emulator uses the IEEE 1149.1
JTAG test access port of the ADSP-2106x to monitor and
control the target board processor during emulation. The EZICE probe requires the ADSP-2106x’s CLKIN, TMS, TCK,
TRST, TDI, TDO, EMU, and GND signals be made accessible on the target system via a 14-pin connector (a 2 row × 7
pin strip header) such as that shown in Figure 5. The EZ-ICE
probe plugs directly onto this connector for chip-on-board
emulation. You must add this connector to your target board
design if you intend to use the ADSP-2106x EZ-ICE. The total
trace length between the EZ-ICE connector and the furthest
device sharing the EZ-ICE JTAG pin should be limited to 15
inches maximum for guaranteed operation. This length restriction must include EZ-ICE JTAG signals that are routed to one
or more ADSP-2106x devices, or a combination of ADSP2106x devices and other JTAG devices on the chain.

Figure 7. JTAG Clocktree for Multiple ADSP-2106x Systems
Figure 6 shows JTAG scan path connections for systems that
contain multiple ADSP-2106x processors.
Connecting CLKIN to Pin 4 of the EZ-ICE header is optional.
The emulator only uses CLKIN when directed to perform
operations such as starting, stopping, and single-stepping multiple ADSP-2106xs in a synchronous manner. If you do not need
these operations to occur synchronously on the multiple processors, simply tie Pin 4 of the EZ-ICE header to ground.
If synchronous multiprocessor operations are needed and
CLKIN is connected, clock skew between the multiple ADSP21062 processors and the CLKIN pin on the EZ-ICE header
must be minimal. If the skew is too large, synchronous operations
may be off by one or more cycles between processors. For synchronous multiprocessor operation TCK, TMS, CLKIN and
EMU should be treated as critical signals in terms of skew,
and should be laid out as short as possible on your board. If
TCK, TMS, and CLKIN are driving a large number of ADSP21062s (more than eight) in your system, then treat them as a
“clock tree” using multiple drivers to minimize skew. (See
Figure 7 “JTAG Clock Tree” and “Clock Distribution” in the
“High Frequency Design Considerations” section of the ADSP-
2106x User’s Manual, Second Edition.)
If synchronous multiprocessor operations are not needed (i.e.,
CLKIN is not connected), just use appropriate parallel termination on TCK and TMS. TDI, TDO, EMU and TRST are
not critical signals in terms of skew.

POWER DISSIPATION ADSP-21062 (5 V)
These specifications apply to the internal power portion of VDD only. See the Power Dissipation section of this data sheet for calculation of external supply current and total supply current. For a complete discussion of the code used to measure power dissipation, see
the technical note “SHARC Power Dissipation Measurements.”
Specifications are based on the following operating scenarios:
Operation Peak Activity (I
DDINPEAK
) High Activity (I
DDINHIGH
) Low Activity (I
DDINLOW
)
Instruction Type Multifunction Multifunction Single Function
Instruction Fetch Cache Internal Memory Internal Memory
Core Memory Access 2 per Cycle (DM and PM) 1 per Cycle (DM) None
Internal Memory DMA 1 per Cycle 1 per 2 Cycles 1 per 2 Cycles
To estimate power consumption for a specific application, use the following equation where % is the amount of time your program
spends in that state:
%PEAK × I
DDINPEAK
+ %HIGH × I
DDINHIGH
+ %LOW × I
DDINLOW
+ %IDLE × I
DDIDLE
= power consumption

I
DDINHIGH
is a composite average based on a range of high activity code. I
DDINLOW
is a composite average based on a range of low activity code.
