Abstract
This paper proposes a FeRAM-based Nonvolatile SOC (NVSOC) to obtain system-level startup acceleration and energy efficiency enhancement for normally-off applications. The NVSOC supports adaptive parallel recovery and two fast startup schemes. The quick power-on detection is enabled by hysteresis-comparator based voltage detector and leakage cutoff controller. A nonvolatile radio frequency controller (NVRF) is first proposed to further boost the recovery of transceivers. Compared with the fastest switching nonvolatile processor based platform, measurement results show NVSOC achieves 3.9× faster running speed and 11× higher energy efficiency to execute periodical normally-off sensing and transmitting tasks. This is the first parallel recovery enabled NVSOC with fast power-on detection and RF initialization capability.
