A Cortex-M3-Based System-On-Chip Architecture for Wireless Communications in Power Grid

This paper presents a Cortex-M3-based system-on-chip (SoC) architecture designed for power-grid-dedicated wireless communication system based on IEEE 802.11ah protocol. The SoC is integrated with a 32-bit embedded microprocessor core using Thumb-2 instruction sets and multiple master/slave devices being compliable with advanced microcontroller bus architecture (AMBA) v2.0 protocol. Along with the various communication interfaces to make the chip more applicable, the whole system can accomplish data communication and processing in power grid applications with high performance and low cost.
