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。
The common signal processing board for multi-DSP shared bus introduces the interface design based on PCI9054 and CPCI bus and analyzes the development of general WDM bus driver. Using Verilog HDL CPLD design control timing to achieve the DSP and CPCI bus bridge PCI9054 ordinary transfer and high-speed DMA transfer. The driver uses DriverWorks and Win-dows driver development kit DDK for development, has good versatility and portability.
