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. 2 Digital Media System-on-Chip (DMSoC) Submit Documentation Feedback www.ti.com TMS320DM6443 Digital Media System-on-Chip 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 allowi
