This paper describes implementation of Web server using Altera Nios II embedded IP core, a configurable general purpose embedded RISC processor with embedded peripheral architecture. A Web server is a computer that delivers Web pages to other computers in the network. Every Web server has a unique IP address and possibly a domain name. Any computer can work as Web server by installing server software. The web server with Nios II processor is called the embedded Web server. The embedded Web server is a highperformance embedded Web server, allows users to monitor and control their embedded applications using any standard browser. The embedded Web server can communicate with the Web browser through TCP/HTTP. The user can use a Web browser and typing URL of Web site into that browser user can examine the Web pages. This Web server does not need dedicated high configuration computer. The Web server application is designed using Altera NiosII embedded platform for uploading the information related to department. The results are verified by connecting it through Intranet with in the campus. This is found to be the cheapest best solution with low power consumption for substituting traditional Web servers. With Nios II soft processor approach, designers can create a "perfect fit" in terms of processors, peripherals, memory interfaces, performance characteristics and cost. This is accomplished by using an Altera Cyclone FPGA to create a custom system-on-chip or a system-on-programmable-chip (SOPC). The SOPC designers are benefited with tremendous versatility in product features, performance, cost and life cycle management.

Design, debug, deploy: The creation of configurable computing applications

JOURNAL OF SIGNAL PROCESSING SYSTEMS FOR SIGNAL IMAGE AND VIDEO technology 2008年第1-2期53卷 187-196页

configurable computing Machines (CCMs) are computing machines based on reconfigurable circuit technology such as field programmable gate-arrays. Early researchers recognized CCMs as a new, flexible, and powerful class of computer. The earliest CCMs featured rudimentary but significant integrated design, debug, and deployment (runtime) environments. This paper reviews those environments and the contributions they made and considers the progress made over the past 20 years in providing support for the "3 D's" of configurable computing application development: design, debug, and deployment. It then introduces an integrated CAD framework for the creation of CCM CAD tools and describes a series of experiments in creating such a CAD tool suite - the JHDL system. The paper reviews lessons learned from that work and concludes by discussing the role integrated design, debug, and runtime environments will play in future CCM-based systems.

A high-temperature data processing device is required for applications gathering sensor data and control of electronics in environments which operate above 200°C. This paper discusses the process of leveraging advances in high temperature electronics and integrating them for new applications and improved system performance. It centers on the development of the 250°C High Temperature (HT) SOI CMOS process technology, several new HT products, and HT package technology. Honeywell integrates a HT FPGA, SRAM and EEPROM into a Multi-Chip Module (MCM) creating a flexible, re-configurable computing platform for sensor data processing and control applications at 250°C. A reconfigurable processor enables the ability to gather information from multiple sources and then control multiple devices with a single electronics assembly while reducing size, weight and power. Packaged in a small 2.2 × 0.75 inch (56 × 18 mm) MCM, the module operates at clock rates up to 10MHz from a single 5V supply. Although power consumption is strongly dependent on configuration, the targeted demonstration configuration clocked at 1MHz power dissipation is on the order of 100mW. The combination of all these technologies and application code to operate the module provides a significant improvement over existing technology for data acquisition applications.

Grid computing can integrate huge services and resources across distributed, heterogeneous, dynamic virtual organizations, and provide tremendous computing power in parallel. Workflow technology enables the user to compose complex Grid applications on distributed heterogeneous and unreliable hardware resources without taking care of lower level details. The drug discovery process almost comprises a number of sub processes, in which various software to be invoked, complex computing and huge amounts of data analyze are involved. Scientific workflow is the process of combining data and processes into a configurable, structured set of steps that implement semi-automated. Distributed processing and parallel computing capacity can improve the Computational efficiency. Therefore, the problems in drug discovery can be solved using the workflow technology. This paper discusses the problem on drug discovery process and presents how to utilize workflow in our eSOC System to resolve the three most important issues in drug discovery. © 2008 IEEE.

Grid computing technology is able to integrate and share large-scale distributed computation and data resource to facilitate the scientific researches. Recently, the grid workflow, support and large-scale distributed data management are becoming two main requirements of scientists and researchers in many fields, such as bioinformatics, high-energy physics etc. In this paper, we proposed to support grid workflow for data intensive applications using scheduling plug-ins in meta-scheduler. We improved the CSF4 scheduling plug-in framework and implemented two scheduling plug-ins, grid workflow and grid data aware. In the new framework, the decision conflict problem of multiple scheduling plug-ins was resolved so that the two scheduling plug-ins can work together smoothly. Moreover, the system is fully extensible and configurable. At last, the experiment results are given to show the improvement of system performance and optimization of scheduling.

A configurable Web Service Performance Testing Framework

A Configurable Web Service Performance Testing Framework

引用

IEEE International conference on High Performance computing and Communications (HPCC)

作者： Jingmin Xie Xiaojun Ye Bin Li Feng Xie Key Laboratory for Information System Security Tsinghua University Beijing China China Information Technology Security Certification Center Introduction Beijing China

More and more softwares based on web service technologies are developed. Before their releases on the Internet, it is necessary to evaluate these systems' performance, especially their response time under different workload pressures. However, existing performance testing benchmarks and tools for web service applications are difficult to adapt to various user-specific testing purposes. This paper proposes a configurable web service performance testing framework which contains client module, application server module and database module. Client module, by using the network cooperation method that one central client drives several other clients, adapts to a great number of concurrent customers to request web services. Application server module contains web services under testing and external supporting web services, each of which is configured as a plug-in. The process to realize mixed ratio of web service interactions is similar to dealing cards and adapts to different commercial application characteristics. In database module, the data model including table and attribute dependence can be customized, and the data scale initialization can be resized according to the topology of above dependence. As such, this framework allows testers to dynamically define their data model, customize their scale of database, configure their transaction characteristics, deploy their application strategies and confirm their performance metrics..

International conference on Field Programmable Logic and applications

It is often desirable to change the logic and/or the connections within an FPGA design on-the-fly without the benefit of a workstation or vendor CAD software. This paper presents a dynamic router for Xilinx FPGAs, designed to run on stand-alone embedded systems. With information obtained from Xilinxpsilas XDL tool, a compact routing database for the Virtex-II/IIP/4 devices is built which only requires 96 KB of storage. A channel routing algorithm is used because of its deterministic execution time and because all routing resources in the channel are available. Sample channels are routed with the router and compared with the Xilinx PAR tool. Improvements in both execution time and in memory usage of several orders of magnitude are observed.
