LED Display Based on FPGA and SDR Sdram

To solve the problem that SRAM only can memorize the smaller pixels and lowly work frequency,the SDR Sdram was used to be as main memory in the research of LED display system.In the experiment,Field Programmable Gate Array(FPGA) was applied to achieve the logical function of every module.Finally the LED Display Screen was controlled reliably,and the pixels of controlled by one master board are 256×128.But in the same condition,the prevenient master board can only control 256×64 pixel.So,it proves the availability of the SDR Sdram controller.
