Abstract:

In the traditional dynamic power management (DPM) architecture , positive policies are generally adopted without considering the great power consumption due to power state transitions , and the policy optimization is not taken into account. This paper aims at the above-mentioned problem and extends the original DPM architecture by adding two modules , namely , the system workload detecting and policy optimizing modules. Several examples are then performed to implement the policy optimization algorithm on the new architecture , which reveals the feasibility and flexibility of the proposed extended architecture.

Key words: dynamic power management architecture, workload detecting, policy optimization
