Abstract Asynchronous logic is a hot topic due to its interesting features of power saving, low noise and robustness to parameters variations. However, its performance analysis is relatively complex. In fact, the handshaking protocol strongly influences the performance of the pipelined architectures. This paper introduces verified Standard-Logic schematics for QDI asynchronous latches and analyzes their characteristics. Buffering capacity and protocol gain are defined and analyzed. Based on this analysis, reduced performance ...
