the MIPS code after loop unrolling the following MIPS code twice, explain the benefits of loop unrolling by calculating the CPI for the original code and the loop unrol twice code. No rescheduling required. You have to show the steps of calculating the CPI final answer without steps will not get credits. points Loop: lw R R add R R R sw R R addi R R bne R R Loop
