Hi All, I am going to use Barrel-Shifter in the Adder/subtractor core, Do you have any other alternative? Do you think that this unit should be a seperate core or part of teh adder? What do you think the effect of this shifter will be? Regards Jamil Khatib __________________________________________________ Do You Yahoo!? Kick off your party with Yahoo!
