Overview
The TMS320DM642AGNZA6, produced by Texas Instruments, is a high-performance Video/Imaging Fixed-Point Digital Signal Processor (DSP) based on the second-generation VelociTI™ very-long-instruction-word (VLIW) architecture (VelociTI.2™). This DSP is part of the TMS320C64x™ DSP generation, which is the highest-performance fixed-point DSP family within the TMS320C6000™ DSP platform. The DM642 device is optimized for digital media applications, offering exceptional performance, operational flexibility, and numerical capability.
With a clock rate of up to 720 MHz, the DM642 achieves performance of up to 5760 million instructions per second (MIPS), making it an excellent choice for high-performance DSP programming challenges. The device features eight highly independent functional units, including six arithmetic logic units (ALUs) and two multipliers, which support various arithmetic operations per clock cycle.
