A Spintronics-Based Nonvolatile FPGA and Its Application to Edge-AI Accelerator

A nonvolatile (NV) field-programmable gate array (FPGA) is quite attractive hardware platform for an internet of things (IoT) device in terms of reconfigurability and ultra-low-power standby power consumption. Moreover, the use of NV logic-in-memory (LIM) circuitry makes it possible to im-prove both area efficiency and energy efficiency. In this paper, some related topics about NV-FPGA, NV-LIM circuitry, and its application to the edge-AI accelerator are presented and its effectiveness is demonstrated.
