Overview
The TMS320DM648CUTD1 is a high-performance digital media processor from Texas Instruments, part of the TMS320C6000™ DSP platform. It is based on the third-generation advanced VelociTI™ very-long-instruction-word (VLIW) architecture, making it an excellent choice for digital media applications. The DM648 device is upward code-compatible with previous devices in the C6000™ DSP platform and offers enhanced functionality and an expanded instruction set. With clock rates up to 1.1 GHz, the C64x+™ core provides up to 8800 million instructions per second (MIPS), addressing high-performance DSP programming challenges.
