TinyMicro ALU

Design the ALU of the TinyMicro. The ALU has two operands, a and b, and one result c. The operation of the ALU is determined by the 2-bit control signals Op as follows:

Op=00, $c=a+b$ .
Op=01, $c=a-b$ .
Op=10, $c=b-a$ .
Op=11, $c=a$ .

Design a parametrized $N$ -bit ALU with a default value of $N=8$ .

Specification

module ALU(a, b, Op, c);
    parameter N=8;
    input [N-1:0] a, b;
    input [1:0] Op;
    output [N-1:0] c;

Input

a and b are the two input operands.
Op indicates the type of operation.

Output

c is the result of the operation.
