摘　　要：为了满足数据采集及信号处理系统中对数据实时性的要求,采用TMS320VC5509为中心处理器,并对A/D转换、电源及复位电路、时钟电路、JTAG仿真电路等外围硬件进行了设计,使其能够在高速采样信号下,及时对数据进行处理,达到系统对处理速度的要求,实现了一种基于DSP的高速数据采集系统设计。In order to meet the demand of data acquisition and signal processing system for real-time. This paper describes a design approach of DSP system, which used the chip TMS320VC5509 as the processing platform, then introduces the design method of A/D conversion, power, reset circuit, clock circuit and JTAG simulation circuit. Above all, the entire system is a high speed data acquisition system based on DSP which can process all of datas in high sampling timely, and satisfies the demand of system for processing speed.
