誰かﾎﾞｽｹﾃ
start:
add $1, $0, $0 ; $1: address of X
addi $2, $0, 16 ; $2: counter = 16
add $3, $0, $0 ; $3: product Z
lw $4, 0($1) ; $4: X, load X to $4
addi $1, $1, 4 ; address + 4
...
loop:
...
add $3, $3, $4 ; Z = Z + X
shift:
...
addi $2, $2, -1 ; counter--
bne $2, $0, loop ; go to loop if counter != 0
sw $3, 0($1) ; store Z
finish: j finish ; dead loop
