Hello everyone.(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to figure this questoin out, it says:

We want to tr4anslate the pseduo instruction "bge $s1, $s2, Lb1" into two real MIPS assembly instructions. Which one is correct.

A:

slt $t0, $s2, $s1

beq $t0, $zero, Lb1

B:

slt $t0, $s2, $s1

bne $t0, $zero, Lb1

C:

slt $t0, $s1, $s2

beq $t0, $zero, Lb1

D:

slt $t0, $s1, $s2

bne $t0, $zero, Lb1

slt stands for set on less than

bne means branch if not equal

beq means branch if equal

and bge is the pseudo instruction that means branch if greater than or equal.

I translated each of the following and none seem to be "if greather than or equal too" i only see, if greather than.

A:

slt $t0, $s2, $s1

if($s2 < $s1) $t0 = 1

else $t0 = 0

beq $t0, $zero, Lb1

if($t0 == 0) goto Lb1

B:

slt $t0, $s2, $s1

if($s2 < $s1) $t0 = 1

else $t0 = 0

bne $t0,$zero, Lbl

if( $t0 != 0) goto Lb1

C:

if($s1 < $s2) $t0 = 1

else $t0 = 0;

if($t0 == 0) goto Lb1

D:

if($s1 < $s2) $t0 = 1

else $t0 = 0

if($t0 != 0) goto Lb1;

None of these seem to work, but B looks like it operates as the branch if $s1 > $s2, but not greather than or equal to. ANy help would be great!

thanks!
