Please, Solve every problem properly.

\begin{tabular}{l|l} 1. & Modify the block diagram for single-cycle datapath that you have been provided so \end{tabular} that it can execute the following instruction. Remember you can't remove or delete any control line. Now, write down the control unit values with the datapath modification. andi \$t0, \$s1, 10 Optimize the following MIPS code, so that there presents no data hazard. Assume the system has forwarding enabled. Now, find out the total execution time with timing diagram for the given table using pipeline method. Iw $s1,20($t1) add $s2,$s1,$t1 addi $s3,$s3,10 sw $s3,20($s0) sub $t2,$s0,$t3 Write down in instructions after performing Code Scheduling. Also, Find out the number of cycles to execute the following instructions after code scheduling. Iw \$s1, 10( \$s0) add \$s3, \$s1, \$t1 sub \$s5, \$s4, \$s 6 sw \$s3, 20(\$so) Iw \$t0, 12(\$so) and $s3,$t0,$t2 sw $s3,20($s0)
