This paper explores the view that the SAN network infrastructure can be an active computational entity capable of supporting certain classes of data intensive computations effectively during communication. The performance is achieved via the use of Field Programmable Gate Arrays (FPGAs) in the network interfaces (NIs). This paper describes the programming model and the design of a prototype har...

Estimating dynamic components in projects involves understanding human factors which are substantial in software development. Communication and collaboration in teams consist of social-driven characteristics with influences on the continuous delivery of software. Efficiently estimated meetings become increasingly important due to budget calculations and shortened release cycles. Experiences of ...

This paper describes a performance evaluation of ImageProcessing applications on FPGA-based coprocessors that are part of general-purpose computers. Our experiments show that the maximum speed-up depends on the amount of data processed by the coprocessor. Taking images with 256 x 256 pixels, a moderate FPGA capacity of 10E+5 CLBs provides two orders of magnitude of performance improvement over ...

In this paper, we address the variability problems in FPGA devices both at design-time and at run-time. We consider a twofold approach to compensate variations, based on measurements issued from digital sensors implemented with FPGA building blocks. We compare two digital structures of sensors; the Ring Oscillator and the Path Delay Sensor. The Ring Oscillator allows a fine grain variability ch...

This paper explores the integration of load balancing features in the data parallel lan guage HPF targeting semi regular applications We show that the HPF virtual pro cessors are good candidates to be the unit of migration Then we compare possible implementations and show that threads provide a good tradeo between e ciency and ease of implementation We nally describe a preliminary implementatio...

This is an investigation of Wireless Sensor Networks (WSNs) using Memsic’s XMesh routing protocol on MICAz wireless motes. It focuses on the study of the practical aspects of WSNs’ power efficiency and network characteristics, which play a critical role in real-word WSN deployments for environmental monitoring. Based on an experimental study and following a quantitative approach, this work exam...

FPGAs have appealing features such as customizable internal and external bandwidth and the ability to exploit vast amounts of fine-grain parallelism. In this paper we explore the applicability of these features in using FPGAs as smart memory engines for search and reorganization computations over spatial pointer-based data structures. The experimental results in this paper suggests that reconfi...

The power-efficient implementation of motion estimation algorithms on a system comprised by an FPGA and an external memory is presented. Low power consumption is achieved by implementing an optimum on-chip memory hierarchy inside the FPGA, and moving the bulk of required memory transfers from the internal memory hierarchy instead of the external memory. Comparisons among implementations with an...

background and objective : poor sleep, poor quality of sleep and sleepiness are among the common problems as-sociated with learning, memory and educational performance in children and adolescents. considering the lack of pre-vious literature in this field, especially in the city of yazd, iran, a number of high-school students of the city participat-ed in a study to assess sleep problems and inf...
