High Speed DMA Data Transfer System Based on PCI Bus

  • 摘要: 提出了基于PCI总线接口技术实现DMA数据传输系统的通用设计方法。该方法应用于雷达接收机综合测试仪,当雷达接收机工作时,采用DMA方式的数据传输速率可以稳定地达到70 MB/s,能够有效地采集并保存雷达各种参数,供主机快速进行雷达故障分析与判断。还重点介绍了数据传输系统中基于PCI总线的接口电路设计及基于WDM的PCI DMA驱动程序的开发。
    Abstract: This paper describes the procedure of designing Direct Memory Access (DMA) data transfer system based on Peripheral Component (PCI) bus interface technology. The system is applied to the test instrument for ladar receiver. When the ladar receiver working, the PCI interface card based on DMA data transfer system can achieve 70 MB/s transfer rates, collect and save the parameter of ladar effectively, and offer the data for computer to analyse rapidly. We emphasize the design of hardware circuit based on PCI bus interface technology and the development of PCI DMA driver program based on Windows Driver Model (WDM).
