On the other hand, asynchronous circuits independently perform only when and where they are needed thanks to preparing timing signals per each element. As a result, they can achieve low power consumption and high dependability. In this research, asynchronous adder circuits and synchronous adder circuits are designed and compared using the 28nm process technology. Then, the advantages of asynchronous circuits under low-voltage environments are quantitatively evaluated by measurement of signal waves and shmoo plots.AA11451459研究報告システムとLSIの設計技術(SLDM)2015-SLDM-17336162015-11-242188-86392015-11-19
