介绍了用vhdl描述的各种硬件电路的实现，基本包括各种常用的电路。-Introduction with VHDL description of a variety of hardware circuits realize, basic, including a variety of commonly used circuits.

用VHDL语言设计简单的CPU，重点设计微操作代码，然后设计CPU各组成模块，最后根据设计的微操作设计微指令，验证设计的正确性。可基本实现加、减、乘、除、移位、循环等操作。-VHDL language is designed to be simple to use the CPU, the focus of the design of micro-operation code, and then design the components of CPU module designed the final design of the micro-operation microinstruction to verify the correctness of the design. Can achieve the basic add, subtract, multiply, divide, transfer, recycling and other operations.
