Research the SDRAM Controller Based on FPGA

Abstract

A global SDRAM controller was designed based on FPGA. The major components of the controller include the interface control module, the command generation module, the data path module, and the source program simulation using Quartus II. From the simulation results, the soft core of the SDRAM controller could complete the mode setting, normal R/W operation, and auto-refresh function. It could easily meet different needs by simple modification, and it is much more flexible and programmable.
