摘要:
A binary adder circuit includes carry evaluation circuits that encode a carry production control signal using two signal values (V, W) such that V=W=0 indicates a carry kill, V=W=1 indicates a carry generate and V.noteq.W indicates a carry propagate. The carry evaluation circuit may be implemented in static or dynamic CMOS logic.
