Based on the Forest & Sullivan market survey. Data centers across the globe now consume around 100GWh of power and this number is expected to increase by 30% by 2016. With growth trends increasing and development expanding, IDC owners realize that small improvements in efficiency, from architecture design to daily operations, will yield large cost reductions over time. Cooling energy is a significant...
Heat emission and temperature control in an electronic device is known to be highly correlated to power consumption as well as to equipment's reliability. Within this context, this paper discusses a possible solution to restrict processing component's heat emission in FPGA-based system (e.g., Cognitive Radio (CR) equipment). It also describes the implementation, on reconfigurable FPGA based circuit,...
This paper introduces a new methodology that characterizes aging-duty cycle and aging-supply voltage relationships that are applicable to minimizing power consumption and task execution time to achieve low Bit-Energy-Ratio (BER). In contrast to the traditional workload balancing scheme where cores are regarded as homogeneous, we proposed a new task scheduler that ranks cores according to their various...
A single-chip CMOS smoke and temperature sensor for use as an intelligent fire detector is proposed. The proposed smoke sensor measures smoke density based on the light-scattering method. The temperature sensor is integrated with the smoke sensor not only to sense heat from a fire but also to compensate for the temperature dependency of the smoke sensor. The prototype chip includes an on-chip photodiode...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
With the development of high rate data transmission technology via distribution line communication, the electric power, data, voice and video can be transferred in the same electric power distribution network, and the technology will be put in operation widely in the future. However the traditional technology of power line communication is not adaptable to the complex and harsh environment of distribution...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
