An Energy-efficient Frame-based Task Scheduling Algorithm for Heterogeneous Multi-core SoC in IoT Devices

As the Internet of Things (IoT) becomes more and more complex, more and more IoT devices begin to use heterogeneous multi-core system on chip (SoC). To solve the problem of high energy consumption caused by using such chips, a three-level task scheduling algorithm for frame-based task is proposed. By combining heuristic method and convex optimization theory, the algorithm has a shorter execution time while achieving near-optimal energy consumption. Simulation results show that compared with some heuristic algorithms, the energy consumption of the algorithm is reduced by 10% to 20%, which is close to the theoretical optimal energy consumption; compared with other algorithms that are also based on convex optimization theory, which have similar energy consumption, the algorithm execution time is reduced 68% 76%.
