Before revision:  To tractably represent a wide variety of next-generation IoT applications, we present a broad IoT application classification methodology based on application functions . Using this classification, we model and analyze the microarchitectural characteristics of a wide range of state-of-the-art embedded system microprocessors, and evaluate the microprocessors' applicability to IoT edge computing. Using these analysis as foundation, we discuss the tradeoffs of potential microarchitectural optimizations  that will enable the design of right-provisioned microprocessors that are efficient, configurable, extensible, and scalable for next-generation IoT devices.
After revision:  To tractably represent a wide variety of next-generation IoT applications, we present a broad IoT application classification methodology based on application functions , to enable quicker workload characterizations for IoT microprocessors. We then survey and discuss potential microarchitectural optimizations that will enable the design of right-provisioned microprocessors that are efficient, configurable, extensible, and scalable for next-generation IoT devices.
