Overview
The TMS320C6421ZDU6 is a high-performance fixed-point digital signal processor (DSP) from Texas Instruments, part of the TMS320C6000 DSP platform. This device is based on the third-generation C64x+ core, which utilizes the advanced VelociTI very-long-instruction-word (VLIW) architecture. The C6421 is designed to handle computationally intensive real-time applications, offering exceptional performance and operational flexibility.
With a clock rate of up to 700 MHz, the C6421 achieves performance of up to 5600 million instructions per second (MIPS) and supports up to 2800 million multiply-accumulates per second (MMACS). The device is fully software-compatible with previous C64x devices, ensuring ease of migration and development.
