Abstract

The design of efficient compressor circuits is a key problem in the design of high-performance applications where the impact of carry propagation must be reduced as much as possible. Examples of application for these compressors extend from arithmetic units such as parallel multipliers to high-performance, high-capacity digital neural networks (DNNs). This paper proposes new, threshold logic based, compressors to improve the delay in the critical signal path. Optimal design of such compressors has been addressed in both logical and electrical directions and our results show that such compressors have the best performance in delay and power-delay product when compared to conventional implementations.
