摘　　要：针对多DSP共享总线的通用信号处理板卡,介绍了基于PCI9054和CPCI总线的接口设计,分析了通用WDM总线驱动程序的开发。采用Verilog HDL用CPLD设计控制时序实现了DSP和CPCI总线桥接器PCI9054之间的普通传输和高速DMA传输。驱动程序采用DriverWorks和Win-dows驱动开发包DDK进行开发,具有很好的通用性和可移植性。For the muhi-DSP sharing bus signal processing card, the design of CPCI bus interface based on PCI9054 is introduced, and the developing of WDM bus driver is analyzed. CPLD control timing is designed in Verilog HDL to realize the high speed DMA transfer between the DSP and CPCI bus bridge. Using DriverWorks and DDK which is the driver developing packet of Windows,the driver is proven to be general and adaptive.
