A spintronics-based power-gated MPU is proposed. It includes a power controller circuit activated by the newly supported power-off instruction for deep-sleep-mode. These means enable the power-off procedure for the MPU to be executed appropriately. The prototype fabricated using 90 nm CMOS and 100 nm MTJ process has successfully operated. The measurement results show that the operation energy can be decreased to 1/28, when the operation duty (active cycle / total cycle) is 10%, compared to non-power-gated MPU.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
