An energy-efficient nonvolatile intelligent processor (NIP) is proposed for battery-less energy harvesting system. This NIP employs RRAM-based logics (NVL) with self-write-termination (SWT) scheme and low-power processing-in-memory (PIM) to achieve computing against frequent power-off situations. test chip was fabricated in 150nm CMOS process using HfO RRAM. achieves 462GOPs/J efficiency at 20MHz clock frequency, showing 13× performance improvement over state-of-the-arts. work presents the first capable of general as well neural network addition integrated PIM.
