| Abstract: | Facing the data accurate transmission problem of cross clock domain in the video capture card through PCI interface,we proposed a low-power consumption asynchronous FIFO memory module,which has a width of 36bits and a depth of 256 to carter the large amount video data demand of burst transfer.Complying with the low-power consumption design strategy,we encoded the address pointer using Gray code to inhibit the metastable state effectively,and a clock gating circuit was added into our design.The module has be... |
