JOP的RAM VHDL源码，经典的经典，不易找到的好东东，-JOP of RAM VHDL source code, classic classics, difficult to find a good price.

实现一个简单的电子钟，其时间（时，分，秒）可以设置和更改，设置和更改的同时不会影响其他显示的变化（相互独立）。-achieve a simple electronic bell, the time (hours, minutes and seconds) can set and change, Settings and change will not affect the other shows the change (independent).

用Verilog描述了一款简单逻辑芯片74HC595的功能该芯片功能为：带输出锁存的8位移位寄存器(use the verilog to describe a simple chip 74HC595 with 8-Bit Serial-In, Parallel-Out Shift Reg and High-Current 3-State Outputs Reg)
