Answer:
Hello the loop required for your question is missing below is the loop
Loop: lw x1,0(x2)
addi x1,x1, 1
sw x1,0(x2)
addi x2,x2,4
sub x4,x3,x2
bnz x4,Loop
answer : attached below
Explanation:
<u>Show the phases of each instruction per clock cycle for one iteration of the loop </u>
loop length
loop
lw x1,0(x2)
addi x1,x1, 1 values attached below
sw x1,0(x2)
addi x2,x2,4
sub x4,x3,x2
bnz x4,Loop
Attached below are the phases of each instruction per clock cycle for one iteration of the loop
Using the computational language C++ it is possible to write a code is possible to create a function that stores items like this:
