ASM and MIPS code

>>57946161
I'm curious, what you want to do ?

Simple things like :
- Find hexa number from an instruction
- Reverse content of two registers..

Come on, easy money.

What do you want to crack, OP ?

Nothing, i'm learning ASM and MIPS and i'm blocked.

Anyone ?

What, you mean shit like this?

; 3xor swap
    xor    $t0,$t0,$t1
    xor    $t1,$t1,$t0
    xor    $t0,$t0,$t1

I have no idea what you're talking about by "Find hexa number from an instruction" - if you're wanting a disassembler or monitor, or if you want assembly language to convert nybbles to ASCII hex, or ... what?

I will give you an example :
sub$t0,$zero,$t1.


I want to find the hexadecimal number who represents this instruction.
If you are good, maybe let's talk in private and if you can help me, send you something on paypal?

Help me please, someone

You mean the actual instruction once assembled?

It's all a matter of looking it up on a greensheet. Find the instruction type and it's structure, I thing sub is an R-type, and then look up the op code for sub, and the register numbers for your arguments, string it all together into the structure, pad as necessary.

So, for example,

sub $t0, $zero, $t1

would assemble into

0x00094022

As the 31-26th bytes are zeroed, for an R-instruction, 25-21 are Rs, in this case also register number 0, 20-16th are Rt, which is register number 9, or $t1, and 15-11 are Rd, which is $t0, which would be 8. Your shift amount is zero, and your funct/ALUop is 23 hex, for the sub instruction.

The binary for that instruction would be

10010100000000100010

Thanks, can we go private to talk please ?

So, can you help me ? In 30-40 minutes, it's done I think.

Come on guys help me, easy money for you.

fuck off. if you can't figure out how instructions get translated into opcodes by yourself, you have no business succeeding in your intro uni course.
