Abstract
Dynamic power management has been adopted in many systems to reduce the power consumption by changing the system state dynamically. This paper explores energy efficiency for systems equipped with PCI Express devices, which are designed for low power consumption and high performance, compared to corresponding PCI devices. We propose dynamic power management mechanism and a management policy for energy-efficient considerations. A case study for a variable-bit-rate LAN device under the PCI Express specification is exploited to provide supports for dynamic packet transmission. Simulation results show that the proposed mechanism and policy would reduce the system energy consumption substantially. © IFIP International Federation for Information Processing 2007.
