Question
The following code is to be scheduled and executed on a two-slot VLIW machine with the goal of achieving a minimum number of cycles. A bundle in this
architecture has two instructions. The first of these instructions can be only an ALU or branch instruction, whereas the second one can be only a load or store
instruction. You are allowed to reorder independent instructions and change the offset of addressing (if needed). You are not allowed to combine instructions.
loop:
Iw r2, 0(r1)
Iw r4, 4(r1)
add r2, r2, r8
add r4, r4, r8
sw r2, 4(r1)
sw r4, 0(r1)
sub r1, r1, -4
bne r1, $zero, loop
Show the instruction bundles issued by the VLIW machine for the above code. Please write one instruction bundle per line.
