摘　　要：提出并实现了一种基于PCI总线的12通道并行采集系统。该系统可实现多路音频并行连续采集，最高数据率每路可达250kSPS。系统采用S5933实现PCI接口及DMA数据传送，控制电路采用CPLD实现，可灵活设置采样率和通道，实现了应用的灵活性。最后，介绍了驱动程序及应用程序，给出了测试结果。目前该系统已成功运行于Windows操作系统。A 12-eharmel parallel syne data acquisition system based on PCI bus has been presented. It can implement continuous multi-parallel audio data acquisition, each eharmel＇s maximum data transfer rate is up to 250kSPS. The system adopts S5933 to implement PCI interface slug and DMA data transfer. The control circuit is implemented by CPLD and the sampling frequency and eharmels can be set flexibly. At the end, the driver and the application program are introduced and test results are also given out. Now the system is carried out on Windows 2000 system successfully.
