摘要
设计了一种基于PCI9656的高速PCI总线接口,数据传输主要为DMA方式。文中介绍了PCI9656的内部结构和功能,讨论了其WDM驱动开发过程,分析了其局部总线在进行DMA传输时的配置时序,提出了一些设计中需要注意的问题。实际应用结果表明,该总线接口性能稳定且优良,可以应用于高速数据传输系统。
This paper presents a kind of high-speed PCI bus interface based on PCI9656,and the main method of transferring data is DMA transmission.This paper introduces the internal functions and structures,and discusses the process of WDM driver developing,and analysis the configuration sequence in DMA transmission at the local bus.At last,it gives some details needed to notice in design.Application results shows that this kind of bus interface works stably and efficiently,and it can be used in the system of high-speed data transmitting.
