Energy-Efficiency on a Variable-Bitrate Device

چکیده
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 variablebit-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.

This paper proposes the Optimized Power save Algorithm for continuous Media Applications (OPAMA) to improve end-user device energy efficiency. OPAMA enhances the standard legacy Power Save Mode (PSM) of IEEE 802.11 by taking into consideration application specific requirements combined with data aggregation techniques. By establishing a balanced cost/benefit tradeoff between performance and ene...
متن کاملRegion Based Minimization of Quantization Error Propagation in Variable Bitrate Video
A bit allocation method is proposed to minimize the propagation of quantization error and thereafter to increase the average quality of encoded video in variable bitrate video applications. In comparison with constant bitrate video, a variable bitrate video can provide better visual quality and coding efficiency for compressed video. Furthermore, while more variation in bitrate is possible we h...

متن کاملSemi-active Control of Building Structures using Variable Stiffness Device and Fuzzy Logic
Semi-active control devices, also called “Intelligent” control devices, constitute the positive aspects of both the passive and active control devices. A semi-active control strategy is similar to the active control strategy, but this control device has been shown to be more energy-efficient than active devices. A particular type of semi-active control device, the Variable Stiffness Device (VSD...
متن کاملAn efficient motion vector coding scheme based on minimum bitrate prediction
Motion vector coding efficiency is becoming an important issue in low bitrate video coding because of its increasing relative bit portion. This work presents a new motion vector coding technique based on minimum bitrate prediction. In the proposed scheme, a predicted motion vector is chosen from the three causal neighboring motion vectors so that it can produce a minimum bitrate in motion vecto...
