Abstract
In asynchronous systems, average function delays principally govern overall throughput. This paper compares the performance of six adder designs with respect to their average delays. Our results show that asynchronous adders (32 or 64-bits) with a hybrid structure (e.g., carry-select adders) run 20-40% faster than simple ripple-carry adders. Hybrid adders also outperform high-cost, strictly synchronous conditional-sum adders
