摘要
随着采集图像的质量越来越高,传统的PCI接口已经难以满足数据传输的要求。PCIe作为PCI的替代品,具有传送速率高,兼容PCI软件等特点,针对图像高速传输的问题,提出了基于PCIe的高速图像采集系统,该系统利用FPGA实现PCIe协议,并针对图像传输设计了总线管理DMA,然后设计了基于PCIe的视频输入输出接口,最后给出了基于FPGA的图像处理算法以及相关的软件功能的实现。
With the increasing quality of images acquisition,traditional PCI interfaces have been difficult to meet the requirements of data transmission.As a substitute for PCI,PCIe has the characteristics of high transfer rate and compatibility with PCI software.For the problem of high-speed image transmission,a high-speed image acquisition system based on PCIe is proposed.The system uses PCI to implement PCIe protocol and designs a bus for image transmission.Manage DMA,then a PCIe-based video input and output interface is designed,and finally an FPGA-based image processing algorithm and related software functions is given.
