Unroll the loop shown below three times and statically schedule to reduce the number of stalls and control overhead. You can assume that the loop executes a multiple of three times. Use registers F12....F30, if needed while unrolling. How many minimum stalls are required to execute this How many number of cycles required for each iteration after scheduling? 12 Now ABCHISO loop?

Expert Answer
To unroll the loop shown three times, we need to duplicate the loop body and adjust the loop counter accordingly. Additionally, we need to statically schedule the instructions to minimize stalls and control overhead. Based on the given information, let's unroll and schedule the loop: Original loop:
