摘　　要：设计了一种基于TMS320VC33的高速多通道信号处理平台。该系统采用DSP+AN2131QC的双处理器结构,CPLD控制系统译码,利用USB1.1通信协议实现与PC机的高速互联通信,具有8路高速数据采集接口、扩展RAM和外部Flash存储器,可独立运行和自举加载程序。平台采用CCS2.0+USB1.1仿真器,实现实时仿真。A fast multi-channel signal processing system based on TMS320VC33 was designed. The system adopts dual processors of DSP and AN2131QC controlled by CPLD, and implements high-speed communication with a PC using USB1.1 conmmication protocol. It has a high-speed data acquisition module with 8 channels, an extended RAM and an extended Flash meraory. Moreover it can operate stand-alone and bootload the user code from the Flash mermory during power up. The system carries out real-time emulation under CCS2. 0 ＋ USB1.1 enviromnent.
