Assuming our standard 5-stage pipeline: loop: sub $t3, $t3, 1 add $t0, $t0, 4 add $t1, $a0, $to $t2,0 ($t1) add $t2, $t2, 1 $t2,0 ($t1) bgt $t3, $zero, loop $t2,0 ($t1) lw SW SW Given sample cache configurations or miss rates, what is the average CPI of the above code for N iterations. What if we increased the cache size and its latency increased? How does this impact performance? Should we repipeline?
