burst mode SDRAM access control system and a control method

TL;DR: In this article, a burst mode SDRAM access control system and burst mode access control method are proposed to solve the problems that the write operation, the read operation and the refresh operation of a storage chip SDRM are very complex and tedious at present, data transmission and storage errors are easy to occur, and the quality of a whole CCD image is influenced.

Abstract: The invention relates to a burst mode SDRAM access control system and a burst mode SDRAM access control method, which solve the problems that the write operation, the read operation and the refresh operation of a storage chip SDRAM are very complex and tedious at present, data transmission and storage errors are easy to occur, and the quality of a whole CCD image is influenced. The control systemcomprises an SDRAM write-in control module, an SDRAM master control module, an SDRAM chip, an SDRAM read-out control module and an SDRAM refresh control module. According to the invention, modular processing is adopted for each operation, so that the program is easy to maintain and modify, a high-reliability and high-efficiency control mode of the large-capacity CCD image data storage chip SDRAM is realized, and the performance of the system is greatly improved.
