碩士 === 國立臺灣大學 === 資訊工程學研究所 === 94 === Dynamic power management has been adopted in many systems to reduce the power consumption by changing the system state dynamically. This thesis 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 a dynamic power management mechanism and a management policy for energy-efficiency considerations. A case study is exploited for a variable-bit-rate (VBD) LAN device under the PCI Express specification to provide dynamic packet transmission support. Simulation results show that the proposed mechanism and policy would reduce the system energy consumption substantially.
