基于FPGA的大屏幕新型控制器设计

One New Type Controller of Screen Design Basing on FPGA

基于克服LED大屏幕传统的DMA控制器占用资源多,异步操作等缺陷,在实际运用中设计了一种专用LED大屏幕DMA控制器。通过仿真及实验验证,专用DMA控制器显示出了其相对于传统LED大屏幕DMA控制器更加优良的性能及应用前景,具有实用价值。

In order to overcome the disadvantages （such as, using more CLB, asynchronous operations and so on） of traditional DMA controller of LED screen, one dedicated DMA controller that adapts to LED screen is designed. By emulation and experiment, the controller shows its high -perform- ance and wide application foreground contrast to the tradition controller, it has utility value.
