1.2 Description

The TMS320DM6443 (also referenced as DM6443) leverages TI’s DaVinci™ technology to meet the networked media encode and decode application processing needs of next-generation embedded devices.

The DM6443 enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution.

The dual-core architecture of the DM6443 provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C64x+ DSP core and an ARM926EJ-S core.

The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously.

The ARM core incorporates:

• A coprocessor 15 (CP15) and protection module

• Data and program Memory Management Units (MMUs) with table look-aside buffers.

• Separate 16K-byte instruction and 8K-byte data caches. Both are four-way associative with virtual

index virtual tag (VIVT).

The TMS320C64x+™ DSPs are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. It is based on an enhanced version of the second-generation high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSP cores an excellent choice for digital media applications. The C64x is a code-compatible member of the C6000™ DSP platform. The TMS320C64x+ DSP is an enhancement of the C64x+ DSP with added functionality and an expanded instruction set.

SPRS282E – DECEMBER 2005 – REVISED MARCH 2007

Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and C64x+ CPU, respectively.

With performance of up to 4752 million instructions per second (MIPS) at a clock rate of 594 MHz, the C64x+ core offers solutions to high-performance DSP programming challenges. The DSP core 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). The eight functional units include instructions to accelerate the performance in video and imaging applications. The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2376 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4752 MMACS. For more details on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide (literature number SPRU732).

The DM6443 also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices. The DM6443 core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 256K-bit direct mapped cache and the Level 1 data cache (L1D) is a 640K-bit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 512K-bit memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two.

The peripheral set includes: 1 configurable video port; a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module; an inter-integrated circuit (I2C) Bus interface; one audio serial port (ASP); 2 64-bit general-purpose timers each configurable as 2 independent 32-bit timers; 1 64-bit watchdog timer; up to 71-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 UARTs with hardware handshaking support on 1 UART; 3 pulse width modulator (PWM) peripherals; and 2 external memory interfaces: an asynchronous external memory interface (EMIFA) for slower memories/peripherals, and a higher speed synchronous memory interface for DDR2.

The DM6443 includes a Video Processing Sub-System (VPSS) that has a configurable Resizer and Video Processing Back-End (VPBE) output used for display.

The Resizer accepts image data for separate horizontal and vertical resizing from 1/4x to 4x in increments of 256/N, where N is between 64 and 1024.

The Video Processing Back-End (VPBE) is comprised of an On-Screen Display Engine (OSD) and a Video Encoder (VENC). The OSD engine is capable of handling 2 separate video windows and 2 separate OSD windows. Other configurations include 2 video windows, 1 OSD window, and 1 attribute window allowing up to 8 levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz, providing a means for composite NTSC/PAL video, S-Video, and/or Component video output. The VENC also provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of 8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs.

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM644x and the network. The DM6443 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS) support.

The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system. Once a PHY candidate has been selected by the ARM, the MDIO module transparently monitors its link state by reading the PHY status register. Link change events are stored in the MDIO module and can optionally interrupt the ARM, allowing the ARM to poll the link status of the device without continuously performing costly MDIO accesses.

The HPI, I2C, SPI, USB2.0, and VLYNQ ports allow DM6443 to easily control peripheral devices and/or communicate with host processors. The DM6443 also provides multimedia card support, MMC/SD, with SDIO support.

For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, available at http://www.arm.com

2.3.2 CP15

2.3.3 MMU

The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and data caches, Tightly-Coupled Memories (TCMs), Memory Management Unit (MMU), and other ARM subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such as supervisor or system mode.

The ARM926EJ-S MMU provides virtual memory features required by operating systems such as Linux®, Windows® CE, Ultron®, ThreadX®, etc. A single set of two level page tables stored in main memory is used to control the address translation, permission checks and memory region attributes for both data and instruction accesses. The MMU uses a single unified Translation Lookaside Buffer (TLB) to cache the information held in the page tables. The MMU features are:

• Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.

• Mapping sizes are:

– 1MB (sections) – 64KB (large pages) – 4KB (small pages) – 1KB (tiny pages)

• Access permissions for large pages and small pages can be specified separately for each quarter of the page (subpage permissions)

• Hardware page table walks

• Invalidate entire TLB, using CP15 register 8

• Invalidate TLB entry, selected by MVA, using CP15 register 8

• Lockdown of TLB entries, using CP15 register 10

2.3.4 Caches and Write Buffer

The size of the Instruction Cache is 16KB, Data cache is 8KB. Additionally, the Caches have the following features:

• Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA)

SPRS282E – DECEMBER 2005 – REVISED MARCH 2007

• Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with two dirty bits in the Dcache

• Dcache supports write-through and write-back (or copy back) cache operation, selected by memory region using the C and B bits in the MMU translation tables.

• Critical-word first cache refilling

• Cache lockdown registers enable control over which cache ways are used for allocation on a line fill,

providing a mechanism for both lockdown, and controlling cache corruption

• Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAG RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the possibility of TLB misses related to the write-back address.

• Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of the Dcache or Icache, and regions of virtual memory.

The write buffer is used for all writes to a noncachable bufferable region, write-through region and write misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a four-address buffer. The Dcache write-back has eight data word entries and a single address entry.

2.3.5 Tightly Coupled Memory (TCM)

ARM internal RAM is provided for storing real-time and performance-critical code/data and the Interrupt Vector table. ARM internal ROM enables non-EMIFA boot options, such as NAND and UART. The RAM and ROM memories interfaced to the ARM926EJ-S via the tightly coupled memory interface that provides for separate instruction and data bus connections. Since the ARM TCM does not allow instructions on the D-TCM bus or data on the I-TCM bus, an arbiter is included so that both data and instructions can be stored in the internal RAM/ROM. The arbiter also allows accesses to the RAM/ROM from extra-ARM sources (e.g., EDMA or other masters). The ARM926EJ-S has built-in DMA support for direct accesses to the ARM internal memory from a non-ARM master. Because of the time-critical nature of the TCM link to the ARM internal memory, all accesses from non-ARM devices are treated as DMA transfers.

Instruction and Data accesses are differentiated via accessing different memory map regions, with the instruction region from 0x0000 through 0x7FFF and data from 0x8000 through 0xFFFF. The instruction region at 0x0000 and data region at 0x8000 map to the same physical 16KB TCM RAM. Placing the instruction region at 0x0000 is necessary to allow the ARM Interrupt Vector table to be placed at 0x0000, as required by the ARM architecture. The internal 16-KB RAM is split into two physical banks of 8KB each, which allows simultaneous instruction and data accesses to be accomplished if the code and data are in separate banks.

The ARM926EJ-S has built in DMA support for direct accesses to the ARM internal memory from a nonARM device. Furthermore, because of the time critical nature of the TCM link to the ARM internal memory, all accesses from non-ARM devices are treated as DMA transfers.

2.3.6 Advanced High-Performance Bus (AHB)

The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the Config Bus and the external memories bus.

2.3.7 Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)

To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an Embedded Trace Macrocell (ETM). The ARM926ES-J Subsystem in the DM6443 also includes the Embedded Trace Buffer (ETB). The ETM consists of two parts:

• Trace Port provides real-time trace capability for the ARM9.

• Triggering facilities provide trigger resources, which include address and data comparators, counter,

and sequencers.

2.4 DSP Subsystem

The DSP Subsystem includes the following features:

2.4.1 C64x+ DSP CPU Description

The C64x+ Central Processing Unit (CPU) consists of eight functional units, two register files, and two data paths as shown in Figure 2-1 . The two general-purpose register files (A and B) each contain 32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or 32 MSBs in the next upper register (which is always an odd-numbered register).

The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and store results from the register file into memory.

The C64x+ CPU extends the performance of the C64x core through enhancements and new features. Each C64x+ .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x

32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputs and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The 32 x 32 bit multiply instructions provide the extended precision necessary for audio and other high-precision algorithms on a variety of signed and unsigned 32-bit data types.

TMS320DM6443

Digital Media System-on-Chip

SPRS282E – DECEMBER 2005 – REVISED MARCH 2007

The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.

The C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2 comparisons were only available on the .L units. On the C64x+ core they are also available on the .S unit which increases the performance of algorithms that do searching and sorting. Finally, to increase data packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack instructions return parallel results to output precision including saturation support.

Other new features include:

• SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size associated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.

• Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many common instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C64x+ compiler can restrict the code to use certain registers in the register file. This compression is performed by the code generation tools.

• Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field multiplication.

• Exceptions Handling - Intended to aid the programmer in isolating bugs. The C64x+ CPU is able to detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and from system events (such as a watchdog time expiration).

• Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a

basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with read, write, and execute permissions.

• Time-Stamp Counter - Primarily targeted for Real-Time Operating System (RTOS) robustness, a free-running time-stamp counter is implemented in the CPU which is not sensitive to system stalls.

2.6 Pin Assignments

Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in the smallest possible package. Pin multiplexing is controlled using a combination of hardware configuration at device reset and software programmable register settings. For more information on pin muxing, see Section 3.5.2 , Multiplexed Pin Configurations, of this document.
