May I ask if I have gotten it right for the following inequality equivalent in MIPS? Or is there any better way to implement with the basic commands of slt and bne and bqe?

less than <
slt $t0, $s1, $s2
beq $t0, $zero, L
  ....
L:

less than equals <=
addi $s2, $s2, 1
slt $t0, $s1, $s2
beq $t0, $zero, L
   ....
L:

greater than >
slt $t0, $s1, $s2
bne $t0, $zero, L
  ....
L:

greater than equals >=
addi $s2, $s2, 1
slt $t0, $s1, $s2
bne $s0, $zero, L

_"[have I] gotten it right?"_ Well, does it produce the desired result? – Michael Mar 24 '15 at 12:02
@Michael I think so, but I am can't be sure~ – toffee.beanns Mar 24 '15 at 12:19
Why not? Just run it in a simulator like SPIM or MARS. – Michael Mar 24 '15 at 12:32
@Michael Yeah! Thanks why didn't I think of that! – toffee.beanns Mar 24 '15 at 13:02
