  • Reconfigurable Computing
    Reconfigurable Computing: A Survey of Systems and Software KATHERINE COMPTON Northwestern University AND SCOTT HAUCK University of Washington Due to its potential to greatly accelerate a wide variety of applications, reconfigurable computing has become a subject of a great deal of research. Its key feature is the ability to perform computations in hardware to increase performance, while retaining much of the flexibility of a software solution. In this survey, we explore the hardware aspects of reconfigurable computing machines, from single chip architectures to multi-chip systems, including internal structures and external coupling. We also focus on the software that targets these machines, such as compilation tools that map high-level algorithms directly to the reconfigurable substrate. Finally, we consider the issues involved in run-time reconfigurable systems, which reuse the configurable hardware during program execution.

  • Reconfigurable Computing
    Reconfigurable computing: architectures and design methods T.J. Todman, G.A. Constantinides, S.J.E. Wilton, O. Mencer, W. Luk and P.Y.K. Cheung Abstract: Reconfigurable computing is becoming increasingly attractive for many applications. This survey covers two aspects of reconfigurable computing: architectures and design methods. The paper includes recent advances in reconfigurable architectures, such as the Alters Stratix II and Xilinx Virtex 4 FPGA devices. The authors identify major trends in general-purpose and special- purpose design methods. It is shown that reconfigurable computing designs are capable of achieving up to 500 times speedup and 70% energy savings over microprocessor implementations for specific applications. 1 Introduction Recent research suggests that it is a trend rather than a one-off for a wide variety of applications: from image Reconfigurable computing is rapidly establishing itself as a processing [3] to floating-point operations [4]. major discipline that covers various subjects of learning, Sheer speed, while important, is not the only strength of including both computing science and electronic engineer- reconfigurable computing. Another compelling advantage is ing. Reconfigurable computing involves the use of reduced energy and power consumption. In a reconfigurable reconfigurable devices, such as field programmable gate system, the circuitry is optimised for the application, such arrays (FPGAs), for computing purposes. Reconfigurable that the power consumption will tend to be much lower than computing is also known as configurable computing or that for a general-purpose processor. A recent study [5] custom computing, since many of the design techniques can reports that moving critical software loops to reconfigurable be seen as customising a computational fabric for specific hardware results in average energy savings of 35% to 70% applications [1].

  • The Paramountcy of Reconfigurable Computing
    Energy Efficient Distributed Computing Systems, Edited by Albert Y. Zomaya, Young Choon Lee. ISBN 978-0-471--90875-4 Copyright © 2012 Wiley, Inc. Chapter 18 The Paramountcy of Reconfigurable Computing Reiner Hartenstein Abstract. Computers are very important for all of us. But brute force disruptive architectural develop- ments in industry and threatening unaffordable operation cost by excessive power consumption are a mas- sive future survival problem for our existing cyber infrastructures, which we must not surrender. The pro- gress of performance in high performance computing (HPC) has stalled because of the „programming wall“ caused by lacking scalability of parallelism. This chapter shows that Reconfigurable Computing is the sil- ver bullet to obtain massively better energy efficiency as well as much better performance, also by the up- coming methodology of HPRC (high performance reconfigurable computing). We need a massive cam- paign for migration of software over to configware. Also because of the multicore parallelism dilemma, we anyway need to redefine programmer education. The impact is a fascinating challenge to reach new hori- zons of research in computer science. We need a new generation of talented innovative scientists and engi- neers to start the beginning second history of computing. This paper introduces a new world model. 18.1 Introduction In Reconfigurable Computing, e. g. by FPGA (Table 15), practically everything can be implemented which is running on traditional computing platforms. For instance, recently the historical Cray 1 supercomputer has been reproduced cycle-accurate binary-compatible using a single Xilinx Spartan-3E 1600 development board running at 33 MHz (the original Cray ran at 80 MHz) 0.

Cheung Department of Computing, Imperial College London, UK ∗∗ Department of Electrical and Electronic Engineering, Imperial College London, UK ∗∗∗ Department of Electrical and Computer Engineering, University of British Columbia, Canada Abstract Reconfigurable computing is becoming increasingly attractive for many applications. This survey covers two aspects of reconfigurable computing: architectures and design methods. Our chapter includes recent advances in reconfigurable architectures, such as the Altera Stratix II and Xilinx Virtex 4 FPGA devices. We identify major trends in general-purpose and special-purpose design methods. I. INTRODUCTION Reconfigurable computing is rapidly establishing itself as a major discipline that covers various subjects of learning, including both computing science and electronic engineering. Reconfigurable computing involves the use of reconfigurable devices, such as Field Programmable Gate Arrays (FPGAs), for computing purposes. Reconfigurable computing is also known as configurable computing or custom computing, since many of the design techniques can be seen as customising a computational fabric for specific applications [102]. Reconfigurable computing systems often have impressive performance. Consider, as an example, the point multiplication operation in Elliptic Curve cryptography. For a key size of 270 bits, it has been reported [172] that a point multiplication can be computed in 0.36 ms with a reconfigurable computing design implemented in an XC2V6000 FPGA at 66 MHz. In contrast, an optimised software implementation requires 196.71 ms on a dual-Xeon computer at 2.6 GHz; so the reconfigurable computing design is more than 540 times faster, while its clock speed is almost 40 times slower than the Xeon processors.

To Lewin, Jan and Huguette for being so patient Foreword "Christophe Bobda’s book is an all-embracing introduction to the fundamentals of the entire discipline of Reconfigurable Computing, also seen with the eyes of a software developer and including a taxonomy of application areas. Reconfigurable Computing is a disruptive innovation currently going to com- plete the most important breakthrough after introduction of the von Neumann paradigm. On software to FPGA migrations a dazzling array of publications from a wide variety application areas reports speed-up factors between 1 and 4 orders of magnitude and promises to reduce the electricity bill by at least an order of magnitude. Facing the tcyberinfrastructure’s growing electricity con- sumption (predicted to reach 35–50% of the total electricity production by the year 2020 in the USA) also this energy aspect is a strategic issue.
