Recently, implementing Radio Access Network (RAN) functionality on cloud-based computing platform has become an emerging solution that leverages the many advantages of cloud infrastructure, such as shared computing resources and storage capacity, while lowering the operational cost. In this paper, we propose a novel caching framework aimed at fully exploiting the potential of such systems through...
Many of the continuing scientific advances achieved through computational biology are predicated on the availability of ongoing increases in computational power required for detailed simulation and analysis of cellular processes on biologically-relevant timescales. A critical challenge facing the development of future exascale supercomputer systems is the development of new computing hardware and...
Mobile Web browsing advancements have largely been driven by the single-minded pursuit of performance. This article takes a different stance and examines the energy efficiency of mobile Web browsing. Focusing on both the network and CPU, the authors find that generational advancements in network technology have reached a point where the mobile CPU is starting to have noticeable impact on Web browsing...
Low power design techniques and efficient wireless solutions have been critical in enabling mobile computing in a ubiquitous and cost-effective manner. While demand for ubiquitous mobile computing continues to rise thanks to an array of new applications, their power budget remains constant due to thermal budget limits and slow improvement in battery technology. Therefore, mobile computing continues...
Over the past five years, we have seen the evolutionary growth of smartphones and tablets. These mobile devices have revolutionized our lives with cutting edge semiconductor and display technologies that play key roles in data processing, communication, multimedia, graphics and imaging as well as display. This paper will describe the path that mobile devices have walked along and provide some perspectives...
This article discusses about Greendroid mobile Application Processor. Dark silicon has emerged as the fundamental limiter in modern processor design. The Greendroid mobile application processor demonstrates an approach that uses dark silicon to execute general-purpose smart phone applications with less energy than today's most energy efficient designs.
Real-time video enhancement is generally achieved using costly specialized hardware that have specific functions and outputs. Commercial off-the-shelf hardware, such as desktop computers with Graphics Processing Units (GPUs), are also commonly used as cost effective solutions for real-time video processing. In the past, the limitations in computer hardware meant that real-time video enhancement was...
Web services are getting popular in the domain of business to business electronic commerce and in automating information exchange between business processes because of the interoperability they provide in a distributed heterogeneous environment. Most existing systems use web services that are hosted in fixed infrastructures. Hosting web services on wireless mobile devices is challenging because of...
With the personal request for treatment and the pressure of decreasing accident, it is necessary particularly to use a new technology in hospital. Using WiFi network, the information of patient will be send to doctor more faster than ever. This will reduce treatment time and cost largely. At the same time, the efficiency of examining ward will be improve. On the other hand, it will avoid treatment...
This article consists of a collection of slides from the author's conference presentation. Some of the specific topics discussed include: What is NVIDIA Tegra?; The Challenge; 3D Features; Interesting Features; 3D Performance; and Demos.
We examine the impact of using flash memory as a second-level file system buffer cache to reduce power consumption and file access latency on a mobile computer. We use trace-driven simulation to evaluate the impact of what we call a FLASHCACHE. We relate the power consumption and access latency of the storage sub-system to the characteristics of the FLASHCACHE: its size, the unit of erasure, and access...
