Storage memory/NVM based executable memory interface IP for advanced IoT applications

Abstract

Internet of Things (IoT) devices is getting increasingly popular in every aspect of life. From health care monitors, activity/sleep trackers to industry/home automation, IoT devices and system-on-chip (SoC) have huge research potential. This paper presents a new memory interface intellectual property (IP) developed for interfacing IoT SoC with storage class memory or non-volatile memory (NVM). So the novelty of this IP is that it enables storage class memory which stands invisible to core as executable memory for low to medium sized IoT SoC's. Currently the devices available in the market have to be synced in to cloud or a device with higher memory bandwidth frequently as the inbuilt SRAM/DDR memory have limited executable memory space. So this interface can be used in the SoC with a high capacity NVM using an interface IP using advanced caching algorithms, this potential limitation can be eliminated.
