摘　　要：在当前,数字信号处理系统越来越倾向于采用基于FPGA的硬件采集处理设备加CPU主控模块相结合的方法。在Windows操作系统中,如何实时的处理硬件送上来的数据成了一个必须解决的问题。这里介绍了一种应用循环缓存的方法,可以处理通过网络、PCI等接口送上来的数据,并且保证了系统运行的稳定性和实时性。At present,the method of adopting hardware based on FPGA and processing equipment combined with CPU master control module is more and more applied in digital signal processing system.In the Windows operating system,how to implement the data sent by the processing hardware has become a problem that must be solved. This paper introduces a method of using the cyclic cache,which can process the data sent through the network,PCI and other interfaces,and ensure the stability and real-time operation of the system.

关 键 词：WINDOWS操作系统 循环缓存 实时性 多线程
