Computer Architecture

As Slide 2 showed the code sequences for the expression C = A + B for four different instruction set designs. References to A, B and C are to memory locations and register references are denoted R1, R2 and R3. Assume instruction op-codes are represented in 8 bits, memory addresses are 64 bits and register addresses are 6 bits Calculate the size of each instruction (in bits) and the total code size for each instruction sequence. there are two other tasks and I attached an example
