Part 1: Design (34 points) Question 1: Consider the addition instruction with flexible second operand Operand2, given below. (10 points) ADD Rd, Rn, Rm, LSL #n It is desired to modify this instruction to the following new syntax. ADD Rd, Rm, LSL #n, Rn This new syntax can be called addition instruction with flexible first operand Operand1. What minimum change in the hardware architecture is required for the implementation of this instruction? (Draw your hardware modifications)
