摘要
基于双口RAM,配合高速单片机、电平转换驱动器以及PCI数据采集卡,设计了一种能够实现DSP图像处理系统与上位PC机之间高速通信的应用电路。介绍了系统组成、接口电路的软硬件实现,以及高速PCI数据采集卡的使用。该电路已应用于某图像处理平台以及相应的测试设备中,通信效果良好。
An application circuit used for high-speed communication between DSP image processing system and PC is designed. The circuit is com- posed of dual-port RAM, MCU, logic level translator and PCI data acquisition card. System composition, interface subcircuit and use of high-speed PCI data acquisition card are introduced. The circuit has been applied to an image processing platform and its testing equipment, and runs normally.
