Description

The TMS320C64x+™ DSPs (including the TMS320DM6431 device) are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The DM6431 device is based on the third-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSPs an excellent choice for digital media applications. The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™ DSP platform. The C64x™ DSPs support added functionality and have an expanded instruction set from previous devices.

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 2400 million instructions per second (MIPS) at a clock rate of 300 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 1200 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 2400 MMACS. For more details on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide (literature number SPRU732).

The DM6431 also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices. The DM6431 core uses a two-level cache-based architecture. The Level 1 program memory/cache (L1P) consists of 32K-byte (KB) memory space that can be configured as mapped memory or direct mapped cache. The Level 1 data/memory memory/cache (L1D) consists of a 64KB memory space that can be configured as mapped memory or 2-way set-associative cache. The Level 2 memory/cache (L2) consists of a 64KB memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or a combination of both.

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; a multichannel buffered serial port (McBSP0); a multichannel audio serial port (McASP0) with 4 serializers; 2 64-bit general-purpose timers each configurable as 2 independent 32-bit timers; 1 64-bit watchdog timer; up to 111-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; 1 UART with hardware handshaking support; 3 pulse width modulator (PWM) peripherals; 1 high-end controller area network (CAN) controller [HECC]; and 2 glueless external memory interfaces: an asynchronous external memory interface (EMIFA) for slower memories/peripherals, and a higher speed synchronous memory interface for DDR2.

The DM6431 device includes a Video Processing Subsystem (VPSS) with a Video Processing Front-End (VPFE) input used for video capture.

The Video Processing Front-End (VPFE) is comprised of a CCD Controller (CCDC). The CCDC is capable of interfacing to common video decoders, CMOS sensors, and Charge Coupled Devices (CCDs).

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM6431 and the network. The DM6431 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.

The I2C port allows DM6431 to easily control peripheral devices and/or communicate with host processors.

The high-end controller area network (CAN) controller [HECC] module provides a network protocol in a harsh environment to communicate serially with other controllers, typically in automotive applications.

The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides.

The DM6431 has a complete set of development tools. These include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into source code execution.
