TMS320DM643 视频/影像定点数字信号处理器
The TMS320C64x™ DSPs (including the TMS320DM643 device) are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The TMS320DM643 (DM643) device is based on the second-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture (VelociTI.2™) developed by Texas Instruments (TI), making these DSPs an excellent choice for digital media 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 DM643 device offers cost-effective solutions to high-performance DSP programming challenges. The DM643 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors.
