MIPS32 help with datapath

Hello!
I'm having problems figuring out the datapath and blocks used for ble and sgt instructions on MIPS32.
After studying a bit I managed to code the instructions for ble and sgt:

Code:


slt $t0, $s2, $s1
beq $t0, $zero, less_equal
////////////////////////////
slt $t0, $s2, $s1

I have no idea how would it look like in the datapath to reverse the registers and how to compute both instructions in ble(slt and beq),so any help is very appreciated!Thanks in advance!

Any tips on how to extend MIPS datapath to support ble and slt instructions would be very helpful!
