基于FPGA高速图像数据的存储及显示设计

High-speed image data storage and display based on FPGA

设计了一种基于FPGA控制Nand Flash阵列实现高速流水线式存储的方案。设计利用FPGA作为主控制器,通过Camera Link输入通信接口将图像数据经过一/二级缓存写入Flash存储阵列中,并采用DMA传输技术将存储后的图像数据上传至计算机硬盘中作进一步处理;同时,利用SDRAM显存实时刷新数据,FPGA构造相应的VGA信号,最终实现100 MB/s图像数据的实时显示。

This paper uses FPGA to control NAND Flash array to achieve high-speed pipelined storage.This design adoptes FPGA as main controller to write image data into the Flash storage arrays through first/second butter,and uses DMA technology to upload image-data to computer hard disk for further processing.SDRAM is utilized to refresh data in real time and FPGA is used to construct corresponding VGA signal to realize 100MB/s image data real-time display.
