Design and Implementation of a PCI Image Data Collecting Card Based on FPGA under CCD System

文章设计了一种基于FPGA的CCD图像数据采集卡。以FPGA作为图像数据采集卡的核心,通过LVDS传输技术,异步FIFO,异步块RAM,SRAM缓存乒乓操作等技术,在PCI核的基础上实现了Initiator下的DMA传输;并基于VxWorks平台编写PCI图像采集卡的驱动程序。经测试和验证,PCI图像采集卡稳定可靠,能够实现数据流为60Mb/s的CCD系统图像数据的高速传输。

This paper introduces the design of a high-speed CCD image data collecting card＇s based on FPGA, and the FPGA is used as the kernel module of the card. By using LVDS transmission technology, asynchronous FIFO, asynchronous block RAM, the initiator burst transfers based on the PCI logic core is realized. The PCI Device Driver under VxWorks is designed and implemented. Through test and verification it is shown that the PCI image collecting card is stable and reliable, it can achieve a high speed transmission of 60Mb/s of CCD system image data.
