ABSTRACT:
An adder (300) generates encoded outputs to conserve power. In particular, the adder provides "B2" encoded outputs which only drive one bit per every two bits at a time on conductive lines in a data processing system. A binary input is encoded by an encoder (800, 304) to generate a plurality of bits. The plurality of bits are concatenated to form a plurality of sum values. A portion of the plurality of sum values are then selectively output in response to a logic value of a carry kill signal, a carry generate signal, and a carry propagate signal.
