使用塞思灵的Spartan-6的lx9型号FPGA实现miniLED屏显示，发现设计的视频切换产生卡顿问题找不到原因？

pfb111111 2020-09-16 06:14:03

小弟最近刚接手一个小的项目，要求用FPGA实现一个mini-LED屏幕的显示模组。带红外遥控以及拨码切换视频文件。实际上这个工作已经完成。但是在测试模组功能时发现使用拨码切会产生屏幕卡顿问题？
另外:代码其实不是我写的，但是我看过了之后没看出什么问题。下面附上一些图片以及部分代码。请各位大神能看看问题在那吗？
工作模式为SPI，从SD卡读数，设计sw123三个开关，通过组合得到8种命令，每个命令对应切换一个文件。

FPGA点屏比Asic点屏的成本和功耗都要高很多呀，是不是没有合适的IC使用嗯，芯动科技承接芯片定制设计服务。

已经查到了，没有加防抖设计。
