1. Using MSI (i.e. functional blocks), show how can you design a circuit that finds the absolute difference (A - B) between two n-bit unsigned integers A & B. [10 points] 2. Write a synthesizable parametrizable behavioral Verilog code for the circuit in (1) above, and simulate it with 4-bit inputs with the following values (4, 8), (4, 4), and (12,9). [10 points]
