Energy efficiency has become one of the top design criteria for current computing systems. The dynamic voltage and frequency scaling (DVFS) has been widely adopted by laptop computers, servers, and mobile devices to conserve energy, while the GPU DVFS is still at a certain early age. This paper aims at exploring the impact of GPU DVFS on the application performance and power consumption, and fu...

The excessively high temperature in a chip may cause circuit malfunction and performance degradation, and thus should be avoided to improve system reliability. In this paper, a novel oscillation-based onchip thermal sensing architecture for dynamically adjusting supply voltage and clock frequency in System-on-a-Chip (SoC) is proposed. It is shown that the oscillation frequency of a ring oscilla...

Graphics processing units (GPU) have been intensively used by high-performance computing applications. However, GPU’s large power consumption is a big issue coexisting with the high parallelism. Although Dynamic Voltage and Frequency Scaling (DVFS) [1] has been heavily studied and successfully applied to real products for saving CPU power consumption, DVFS is still relatively new for GPU energy...

A dynamic energy performance scaling (DEPS) framework is proposed to save energy in fixed-priority hard real-time embedded systems. In this generalized framework, two existing technologies, i.e., dynamic hardware resource configuration (DHRC) and dynamic voltage frequency scaling (DVFS) can be combined for energy performance tradeoff. The problem of selecting the optimal hardware configuration ...

Dynamic voltage and frequency scaling (DVFS) is a commonly-used power-management technique where the clock frequency of a processor is decreased to allow a corresponding reduction in the supply voltage. This reduces power consumption, which can lead to significant reduction in the energy required for a computation, particularly for memory-bound workloads. However, recent developments in process...

A key concern in embedded systems today is power consumption. Increasing demands for longer battery life and heating issues associated with power have led researchers to develop new ways to reduce power and energy consumption in embedded systems. Dynamic voltage and frequency scaling (DVFS) techniques are used to dynamically alter the voltage and frequency levels of the CPU to the lowest possib...

Networks-on-Chip (NoCs) are a general purpose, scalable replacements for shared medium wired interconnects offering many practical applications in industry.
