是用verilog写的带uart的简单controller，使用的是mips指令，用modelsim仿真，波形正确-With uart verilog write a simple controller, use the mips instruction the modelsim simulation, waveform correctly

32位MIPS指令CPU，实现31条指令，并且附带LED，七段数码管，VGA，键盘，UART等外设接口-32 MIPS instruction CPU, a 31 instructions, and comes with LED, seven-segment LED, VGA, keyboard, UART peripheral interfaces
