视频图像处理系统中SDRAM控制器的FPGA实现!
Implementation of SDRAM controller based on FPGA in video image processing system
摘要
Abstract
In order to achieve real-time processing of image data in video image processing,using the large capacity memory to complete the data cache is one essential step.It presents a SDRAM controller solution to FPGA chip in the realization of image data cache during video image pro-cessing in view of the working principles and time sequence characteristics of SDRAM.According to the requirement for real-time image data transmission rate,the operation mode is configured as full-page burst read and write and auto-refresh,with each operation modularization made and controlled by a total state machine.The design is implemented with Verilog.The result show that the controller is used to complete image data cache in the video image processing successful-ly,and that it has advantages of high READ/WRITE rate,simple control and low price and so on.关键词
