TMS320C51PQ57
数字信号处理器 DIGITAL SIGNAL PROCESSORS
description
The TMS320C5x generation of the Texas Instruments ™ TMS320 digital signal processors DSPs is fabricated with static CMOS integrated circuit technology; the architectural design is based upon that of an earlier TI DSP, the TMS320C25. The combination of advanced Harvard architecture, on-chip peripherals, on-chip memory, and a highly specialized instruction set is the basis of the operational flexibility and speed of the ’C5x‡ devices. They execute up to 50 million instructions per second MIPS.
