Overview
The TMS320DM648, produced by Texas Instruments, is a high-performance digital media processor part of the TMS320C6000 DSP platform. This processor 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, it achieves performance of up to 8800 million instructions per second (MIPS), making it suitable for high-performance DSP programming challenges.
