Unlike DSP compilation for high performance, research for low power optimisation has received little attention, although power dissipation is a critical issue for mobile devices. This paper presents an overview of power consumption models and power saving techniques for embedded DSP processors applications and evaluates their application to the Texas Instruments TMS320VC5510 Digital Signal Proc...

The integration of the wireless LAN technology in mobile devices as cellular phones or PDAs has become a user need due to its popularity in providing high speed wireless Internet access at a low cost. Such devices though should meet users’ expectations with regard to QoS, e.g., guarantee a reasonable voice quality when VoIP is used, and power saving efficiency, e.g., standby and calling times s...

As processor power density increases, thermal and power control becomes critical for packet processing. Network applications feature ON/OFF execution pattern, which causes frequent temperature and power consumption changes in the processor. In this paper, we propose a novel power aware thermal management algorithm, which achieves power saving in multicore processors by employing a vacation sche...

While the 802.11 power saving mode (PSM) and its enhancements can reduce power consumption by putting the wireless network interface (WNI) into sleep as much as possible, they either require additional infrastructure support, or may degrade the transmission throughput and cause additional transmission delay. These schemes are not suitable for long and bulk data transmissions with strict QoS req...

IEEE 802.16e standard have been designed for both delay sensitive and delay tolerant applications. This paper presents energy-saving strategies by extending unavailability interval for multiple power saving classes simultaneously. The proposed model allows mobile stations to dynamically adopt multiple sleep mode operation or multiple partial sleep mode operation based on the buffer status of po...
