基于PCI总线的图像处理及传输系统的设计

PLX公司的PCI 9054是一种通用的PCI总线接口芯片,可方便地进行软硬件开发实现PCI总线桥接。介绍了利用PCI 9054开发的图像处理及传输系统和配套的WDM驱动程序,以FPGA为系统硬件框架核心,从接口LVDS和RS 422读入图像数据及其他同步帧数据,经过处理后通过PCI接口芯片及PCI驱动程序进行与计算机系统的数据交换,从而实现基于PCI总线的高速图像传输处理。利用PCI 9054开发PCI高速数据传输系统具有较好的性价比。

Design of a Image Processing and Transfering System Based on PCI Bus

The PCI9054 is an universal PCI bus-chip developed by PLX Co.,who has facility with bridging PCI bus by expediently hardware and software developing.Image processing and transfering system based on PCI9054 bus chip and the corresponding WDM drivers is briefly introduced.Hardware with FPGA centered,acquire the image data and the frame data from the LVDS and RS-422 interface,and exchange the processed data with computer system by using the PCI interface chip-set and the PCI device driver.Figure out the sketch of high speed image processing and transfering system.The application of PCI9054 in high speed data transfering system based on PCI bus is evidently appropriate.
