Dynamic Power Management for Dark Silicon Multicore Processors

Multicore processors in the dark silicon era will be over-provisioned with multiple cores of different types and will have to satisfy stringent power constraints while maximizing performance. As such, a critical research problem is that of developing new, effective, and scalable run-time dynamic power management techniques and algorithms to effectively make use of the over-provisioned but power-constrained computational resources on a chip. This chapter surveys the state of the art on this subject and dives in-depth into three specific dynamic power management solutions for multicore processors in the dark silicon era.
