Temperature-Aware Scheduling for Embedded Heterogeneous MPSoCs with Special Purpose IP Cores

Many embedded heterogeneous MPSoCs integrate general purpose cores along with special purpose cores. The power states of these cores are usually controlled by an internal hardware controller rather than the central operating system. In this paper, we propose a thermal management technique which redu...

Description
Summary:Many embedded heterogeneous MPSoCs integrate general purpose cores along with special purpose cores. The power states of these cores are usually controlled by an internal hardware controller rather than the central operating system. In this paper, we propose a thermal management technique which reduces the performance penalty of central thermal management by considering these special purpose cores and the performance requirements of the tasks running on them. Our experimental results show that for the workloads with high priority special purpose tasks, our technique can reduce the occurence of thermal violations by at least 3X while improving the weighted execution time by up to 24\%.
