ALU

代码说明：

说明：  包含一个ALU，实现斐波那契数列的计算。1.接受两个6位二进制输入。2.通过手动输入的时钟驱动每个周期进行一次计算。3.结果输出到led灯（使用NEXYS4开发板）(Including an ALU to realize the calculation of Fibonacci sequence. 1. Accept two 6-bit binary inputs. 2. Each cycle is driven by a clock input manually. 3. Output to LED lamp (using NEXYS4 development board))
