SDRAM控制器简易化设计

摘要

SDRAM存储芯片拥有快速读写的性能，可以应用以回波模拟系统作为数据高速缓存器。SDRAM芯片是由SDRAM控制器控制的，SDRAM控制器有严格的控制时序和工作状态，可以使用有限状态机理论和VerilogHDL语言对FPGA进行模块化开发设计。笔者基于FPGA给出了一种SDRAM控制器简易化设计方法．实验结果表明该方法简化了SDRAM控制器的设计。%SDRAM has fast reading and writing ability,it could be used as a data cach in echo simulation system.SDRAM is controlled by SDRAM controller. With strict time sequence and working states, SDRAM controller could accurately read or write data,which was developed and designed in the way of modularization,with finite state machine （FSM） theory and in VerilogHDL language on FPGA. Based on FPGA,the author put forward a easy design method of SDRAM controller. The result shows that this method simplifies the SDRAM controller design.
