Need ALU design help

  1. Apr 12, 2008 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant equations

    3. The attempt at a solution

    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!
