Draw the circuit

A hard-wired control unit has been designed for the following AHPL control sequence: 1. B[0:3] 2. A[0:3] + 3. Z = A; Alcoa - Abeal Acasa y 2 A [0:3]; a, a)/(2,3). A1:3], A [0]; (b, b)/(3,2). (1). Both A and B are 4-bit registers made of D flip-flops, a, b are combinational inputs, and Z is a bus. A hard-wired control unit has been designed for the following AHPL control sequence: 1. B[0:3] 2.
