Q1: Basic Circuit (10 marks) An arithmetic circuit that performs addition, subtraction, minimum, and absolute operations is defined in Table Q1. Note that a, b, and arith are 8-bit signed numbers. Table 1 CiCo Function Operation 00 Addition arith = a + b 01 Absolute arith = b 10 Subtraction arith = a - b 11 Minimum arith min (a,b) Based on the functional table in Table Q1, code the arithmetic unit using the behavioral modeling style in Verilog
