利用vhdl模拟实现CPU的功能，实现其中的加减乘除等多种运算-CPU utilization of vhdl simulation of the realization of the function, the realization of which, such as addition and subtraction, multiplication and division multiple computing

poc即为cpu与外部设备，比如打印机的接口，用VHDL的编程来实现poc功能的仿真-poc is the cpu with an external device, such as the printer' s interface, programming with VHDL simulation capabilities to achieve poc

一个简单的CPU设计，支持add，sub，mvi，mv四条指令，用Verilog语言编写，在Quratus II上编译通过，仿真正确。-A simple CPU design, support add, sub, mvi, mv four instructions, with the Verilog language, compiled by the Quratus II, the simulation is correct.

this document descr ipt the implementation os cpu microprocessor on fpga with vhdl code style and simulation on with modelsim.
