Abstract:
The authors describe a new conditional-sum rule for low power applications. This conditional sum adder is especially attractive for implementing high-speed arithmetic systems. The new conditional sum addition rule can reduce the internal nodes and multiplexer numbers of the adder design. Various supply voltages and circuit structures are used to implement the new conditional sum adders. It is shown that about 10% to 25% power-delay product is saved
