摘　　要：介绍了一种PCI接口卡中DMA模块的软件和硬件设计,该设计硬件部分基于Altera公司的FPGA芯片实现,软件驱动部分通过DriverStudio和WinXPDDK软件在VC++6.0环境下开发完成。该系统不仅可以实现计算机和PCI卡上本地数据信号的高效双向交换,并且为应用层软件的编写提供了方便的接口函数。This article introduced a hardware and software design of DMA module in a PCI card. The hardware design was based on an Altera FPGA IC, the software design was completed with DrvierStudio, WinXPDDK and VC ＋ ＋ 6.0. With this design, data can be exchanged between the computer and the PCI card local side efficiently. It also provides interface functions which is convenient for application software to transfer data from/to driver software.
