Design a simple ALU. There are 2 inputs, A and B, and each one is stored in 16-bit register and a 3-bit opcode. The output is a 17-bit register Y. The opcode controls ALU functions as follows: Opcode Function 000 001 010 011 100 101 110 111 Operation Y <= A Y <= A + B Y<=A-B Y <= A AND B Y <= A OR B Y <= A + 1 Y<=A-1 Y <= B A Add Subtract AND OR Increment A Decrement A B Write the full VHDL code for your design use your student ID as name of your top-level entity Hint: use multiplexer and simple logic and arithmetic assignments.
