چکیده
For mobile 3D graphics systems, even though performance requirements are met, an efficient power management is even more important for battery-powered mobile devices since they require a large number of arithmetic operations as well as a high frequency of memory accesses. According to the analysis of the power consumption of mobile 3D graphics pipelines and the slacks across the pipeline stages, we describe intra-frame and inter-frame DVS low-power techniques reducing the power consumption of mobile devices based on a variable voltage processor. Our implementation on a PDA development board shows that the proposed DVS techniques achieve an energy saving of up to 46% over a non-DVS implementation.

Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...

متن کاملA Minimal-Cost Inherent-Feedback Approach for Low-Power MRF-Based Logic Gates
The Markov random field (MRF) theory has been accepted as a highly effective framework for designing noise-tolerant nanometer digital VLSI circuits. In MRF-based design, proper feedback lines are used to control noise and keep the circuits in their valid states. However, this methodology has encountered two major problems that have limited the application of highly noise immune MRF-based circui...

A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.
