  • Zero result prediction
    Patent number: 6629118
    Abstract: A zero result detector for detecting a zero result in the sum of a first operand A, a second operand B and a carry bit Cin operates by calculating {overscore (A)} and {overscore (A)}+1 and then comparing one of these with B (Cin=O, {overscore (A)}; Cin=1, {overscore (A)}+1) in dependence upon Cin. If the comparison shows equality, then the zero detect result Z is true.
