 Use Verilog HDL code to synthesize the General Purpose Microprocessor (GPM). The GPM is broken down into two parts: Datapath (DP) and Control Unit (CU). Write the DP and CU code seperately then combined into a top module (DP + CU). The purpose of the GPM is to determine the Greatest Common Divisor (GCD) between two integers.
