摘要
针对多DSP分布式互连的信号处理板卡,介绍基于PCI9054和FPGA的CPCI总线接口设计,分析通用WDM总线驱动程序的开发。接口设计引入数据包存储转发的方法,这种方法在分布式系统中可扩展性好、效率高。另外驱动程序采用DriverWorks进行开发,具有很好的通用性和可移植性。
On the basis of the distributed Multi- DSP inter- linking signal processing board, the design of compact PCI bus interface based on PCI9054 and FPGA is introduced. Then the development of general WDM bus driver is analyzed in this paper. The design of interface introduces the method for data package store and forward. This method has the advantages of being extensible and having high efficiency in distributed system. Besides,the driver which is developed by using DriverWorks is universal and transplantable.
