摘　　要：研究了PCI计算机总线超高速数据采集与DSP系统的设计与实现 .系统采用PCI总线及I ,Q支路双通道设计 ,通道采样率均为 5 0 0MHz ,系统存储深度为 2MB ,中央处理器采用高速DSPTMS32 0C6 2 0 2 ,时序和逻辑电路由E PLD实现。实际测试结果表明 ,系统工作正常 ,证明系统原理与硬件设计是成功的。The design and realization of ultra high speed data acquisition and DSP system based on PCI bus are discussed.PCI bus and I,Q channels are adopted in the design and the sampling rate in each channel reached 500MHz.The memory deep of the system is 2MB and CPU is DSP TMS320C6202.The timing and logic function are fulfilled by EPLD. The test result indicates that the system works normally and the system principle and hardware design are successful.
