基于FPGA的视频图像加密系统 DE2_70+TRDB—D5M+VGA(FPGA-based video encryption system DE2_70+TRDB-D5M+VGA)

基于FPGA的数字钟的设计，外部时钟32MHz，通过分频器得到秒脉冲，用于正常工作时的计数脉冲。通过分频还得到一个5ms的脉冲，用于按键的消抖（具体原理可见程序）。输入的信号有三个：1.时钟信号2.校时模式设置按键3.校时调整按键，输出通道6位数码管。共有：校时模块，24计数的小时计数模块，60计数的分钟计数模块，60计数的秒钟计数模块。

该模块实现一个寄存器堆的操作，其中前16个仅主机能写，规给为32-bit×32。后16个仅Micorblaze能写。读取没有限制。如果双方同时对同一地址进行读写操作，读回的数将是全1。(This module implement a register file of the operation, of which the first host 16 is only able to write rules to the 32-bit × 32. Micorblaze only 16 after the write. There is no limit to read. If the two sides at the same time to read and write operations to the same address, read back would have been a full one.)
