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.
