A NULL convention full adder receives a plurality of inputs, each having an asserted state and a NULL state. The adder switches its output to an asserted state when all inputs have been received and summed. The adder switches its output to the NULL state only after all inputs have returned to NULL. A register can be incorporated into each full adder. Multiple full adders are combined into multi-bit adders with registration.
