摘　　要：阐述了基于S5933 PASS-THRU通道数据传输的机理,提出了利用S5933开发PCI总线数据采集系统解决方案,避开了PCI总线控制器设计的难题,节约了成本和开发时间.同时采用通用大规模集成器件(CPLD),设计实现了32路数字采集通道,提高了数据传送速率,节约了CPU资源和PCI总线资源.The paper explains the data transfer mechanism based on the PASS-THRU channel of S5933, and gives a method to develop data acquisition system based on PCI bus, the problem of designing the PCI interface controller is avoided, saving time and cost of development production. The use of CPLD makes the stucture of the system more integrated. The 32-bit data acquisition system,the speed of data transmission is faster,the CPU resource and PCI bus resource are spared.
