You are given the following code. Note that floating$-$point instructions use floating point registers labeled f$.$ Integer instructions use integer registers labeled x$.$ Remember that the first operand is the destination. The memory address referenced in fld and fsd are obtained by adding the displacement to the value in the index register.

loop: fld f$0,0($x$1)$

fld f$2,0($x$2)$

fadd f$6,$f$2,$f$12$

fsub f$4,$f$0,$f$10$

fmul f$8,$ f$4,$ f$6$

fsd f$8,0($x$2)$

subi x$1,$ x$1,8$

subi x$2,$x$2,8$

bnz x$1,$ loop

We are given the following latencies for the different types of instructions.

Floating Point Add$/$Sub $-3$

Floating point Multiply $-5$

Load$/$Store $-2$

Integer arithmetic $-1$

Branch if not taken $-1$

Branch if taken $-2$

a$).$ Show how many cycles are needed to complete one iteration without reordering. DO NOT use delayed branch.

b$).$ Reorder instructions and show how many cycles are needed to complete one iteration. BE CAREFUL

TO ADJUST OFFSETS WITH fsd WHEN YOU REORDER INSTRUCTIONS.
