Need ALU design help
Hello!


I need to implement a set greater than and a branch less or equal in my 16 bit ALU design(MIPS architecture),but I'm having many difficulties.
I know that in a set greater than a>b equals a-b>0 ,but I don't know how to work out from that and implement it in my design(which type of gates to use and that).
The same happens with branch less or equal.I already have a branch equal,but I don't know how to use it in order to get a ble.
Any help is really appreciated!

OK, first off, is this a simulation you are writing in code, or one you are creating in a circuit simulator like LogicWorks (if the latter, I may even know the professor you're taking the class from)? If it's a program you're writing, what language is it written in, and how are you implementing it?

Well,I'm using xilinx to design the ALU(does not involve coding) using mux,gates,etc.
