The security implications of on-chip voltage regulation on the effectiveness of various voltage/frequency scaling-based countermeasures such as random dynamic voltage and frequency scaling (RDVFS), random dynamic voltage scaling (RDVS), and aggressive voltage and frequency scaling (AVFS) are investigated. The side-channel leakage mechanisms of different on-chip voltage regulator topologies are ...

Low power embedded processing is known to rely on dynamic voltage-frequency scaling (DVFS) in order to optimize energy usage (and therefore battery life). However, low voltage operation exacerbates the incidence of soft errors. Similarly, higher voltage operation (to meet real-time deadlines) is constrained by power dissipation (and associated thermal) maxima as dictated by hard failure rate li...

Internet-of-Things (IoT) is an appealing service to revolutionise Smart City (SC) initiatives across the globe. IoT interconnects a plethora of digital devices known as Sensor Nodes (SNs) Internet.

Three-dimensional integration has the potential to increase integration density and to reduce communication latency of chip-multiprocessors (CMPs). However, high power density (i.e., power dissipation per unit volume) due to the high integration incurs temperature-related problems in reliability, power consumption, performance, and system cooling cost. In this paper, we propose a design-time so...

Reducing power consumption has been an essential requirement for Cloud resource providers not only to decrease operating costs, but also to improve the system reliability.

Information and communication technology (ICT) has a profound impact on environment because of its large amount of CO2 emissions. In the past years, the research field of ‘‘green’’ and low power consumption networking infrastructures is of great importance for both service/network providers and equipment manufacturers. An emerging technology called Cloud computing can increase the utilization a...

As energy management on energy-constrained devices continues to challenge researchers and frustrate users, device designs are addressing the problem by integrating more hardware components that can trade off energy and performance. Dynamic voltage-and-frequency scaling (DVFS) allows CPUs and memory to trade off speed and energy, buffering and polling rates allow radios to trade off latency and ...

Energy efficiency and energy-proportional computing have become major constraints in the design of modern exascale platforms.
