Dynamic power management for multidomain system-on-chip platforms: an optimal control approach

摘要

Power management for increasingly complex microprocessor systems-on-chips (MPSoCs) is a significant challenge. Existing linear control models are ineffective where communications are via a network-on-chip (NoC), and these controls cannot adequately manage power dissipation. This can lead to inefficient communication and resource allocation in MPSoCs. The authors propose a new power control approach based on fractal-state equations. They report significant runtime power savings for a variety of benchmark applications. The 20-page paper, while not for the faint of heart, should be of interest to those in the field.
