Datapath mentioned in question:

Problem 2 (20 points) Consider the datapath above. The instruction being decoded has the bit field 000000 000100 10011 001 01011 0010011 a) What is this instruction, what are the values of each control line and why? b) What will be the bits in the destination register after the instruction is executed, assuming the initial value in the argument register was 1010? c) If PC for the instruction in question a) is 0000 0000 0042 0016 hex, what value will it have after the instruction in question a) finishwed and why?
