Shuffle X07222

Design a shuffle circuit. It has two inputs (in1 and in2), two outputs (out1 and out2) and one control signal (swap). When swap=0, the inputs must be transferred to the outputs in the same order, i.e., out1=in1 and out2=in2. When swap=1, the inputs must be swapped, i.e., out1=in2 and out2=in1.

Specification

module shuffle(in1, in2, swap, out1, out2);
    input in1, in2, swap;
    output out1, out2;

Input

• in1 and in2 are the inputs of the shuffle.

• swap is the control signal.

Output

• out1 and out2 are the outputs of the shuffle.
