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 local-area-network 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. © 2008 Springer Science+Business Media, LLC.[SDGs]SDG7Bit rates; Dynamic power management; Energy efficient; Low-power consumption; Management policy; Network devices; Packet transmissions; PCI Express; Simulation result; System energy; System state; Variable bit rate; Computer peripheral equipment; Dynamics; Energy efficiency; Energy policy; Interfaces (computer); Local area networks; Ubiquitous computing; Electric power measurementconference paper10.1007/s11265-008-0280-92-s2.0-77951252560
