    invited paper:

    Data-Stream-Based Computing: Models and Architectural Resources;

    International Conference on Microelectronics, Devices and Materials (MIDEM 2003), Ptuj, Slovenia, Oct.1-3, 2003

    Abstract:
    Embedded System Design often turns hardware / software co-design into hardware / configware / software co-design. The transition from HDL languages to sources of higher abstraction levels, like System-C and others, encourages to go from complex design flows to compilation techniques which are supported by a simple machine paradigm model. Because the instruction-stream-based von Neumann mind set does not support configware compilation we need a data-stream-based second model, which has been popularized recently by a number of projects in reconfigurable computing, and even for a hardwired solution. The paper introduces this anti machine model and its archtectural resources in detail.  -- ppt  --  pdf  --  fm

    Abstract:
    The paper is beginning with a survey on paradigm shifts affecting academic mind sets. Then the paper points out, how reconfigurable platforms and their applications introduce fundamental padadigm shifts colliding with the tradional backgrounds of EE and CS professionals. This has a heavy impact on several areas, such as design automation, embedded system design, parallel algorithms, compilation techniques, computing machine principles and architectures and other areas. Our academic education system is heading toward a desaster, where our graduates will not be sufficiently qualified to meet the requirements of the labour market. The paper discusses proposals to solve these problems.

    Abstract.
    Reconfigurable computing has proceeded from niche to mainstream. This is not new any more. But now the provocative mind set, hidden behind its methodology, is heading toward a fundamental EECS curricular revolution. The talk introduces the principles of this antimatter
    of computing science. However,  in contrast to particle physics, merging matter and antimatter  does not lead to annihilation, but to synergies. This provides a promising alternative to hardware software so-design: configware / software co-design

    3rd Workshop.on  Enabling Technologies for System-on-Chip Development 2001   _
    November 19-20, 2001,  Tampere, Finland.      -   see the program

    Abstract. Making gate arrays obsolete, FPGAs are successfully proceeding from niche to mainstream. Like microprocessor usage, FPGA programming is RAM-based, but by structural programming (also called "(re)configuration") instead of  procedural programming. Now both, host and accelerator are RAM-based and as such also available on the same chip: ready for SoC design.

    Now also accelerator definition may be -at least partly- conveyed from vendor site to customer site, such as e. g. for upgrades. A new business model is needed. But this paradigm switch is still ignored: FPGAs do not repeat the RAM-based success story of the software industry. There is not yet a configware industry, since mapping applications onto FPGAs mainly uses hardware synthesis methods, but not really compilation. Supporting only fine-grained reconfigurability of roughly single bit wide configurable logic blocks (CLBs) the mapping tools are mainly based on gate level methods - similar to CAD  for hardwired logic.

    From a decade of world-wide research on Reconfigurable Computing another breed of reconfigurable platforms is an emerging competitor to FPGAs.  In contrast to FPGAs, the Reconfigurable Computing scene uses arrays of coarse-grained  reconfigurable datapath units (rDPUs) with drastically reduced  reconfigurability overhead: to directly configure high level parallelism. But the classical machine paradigm does not support soft datapaths because “instruction fetch” is not done at run time.

    To introduce the new business model to cope with the current accelerator design crisis a transition from CAD  to compilation is needed,  and from hardware/software co-design to configware/software co-compilation.  The paper illustrates such a roadmap to reconfigurable computing, supporting the emerging trend to platform-based SoC design.

    "Reconfigurable Computing:
    the Roadmap to a New Business Model
    - and its Impact on SoC Design"

    Abstract. Making gate arrays obsolete, FPGAs are successfully proceeding from niche to mainstream. But after a decade of  research on Reconfigurable Computing a new breed of reconfigurable platforms is an emerging competitor to FPGAs: coarse grained reconfigurable platforms with drastically improved efficiency.

    Like microprocessor usage, also programming reconfigurable platforms is RAM-based, but by structural programming instead of  procedural programming. But so far reconfigurable platforms do not yet repeat the RAM-based success story of the software industry. Because of lacking awareness of this paradigm switch there is not yet a configware industry. A new business model is needed, as well as a fundamentally new product design flow approach.

    This embedded tutorial surveys a decade of R&D on Reconfigurable Computing and related CAD. The paper illustrates, that results are available for commercialization: to cope with the current SoC design crisis by a transisiton from hardware/software co-design to to platform-based SoC design by configware/software co-compilation. The paper shows a roadmap to the success story of a coming  configware industry.

    Reconfigurable Computing: a New Business Model - and its Impact on SoC Design

    Abstract. Making gate arrays obsolete, FPGAs are successfully proceeding from niche to mainstream. Like microprocessor usage, FPGA application is RAM-based, but by structural programming (also called "(re)configuration") instead of  procedural programming. Now both, host and accelerator are RAM-based and as such also available on the same chip: a new approach to SoC design.

    Now also accelerator definition may be -at least partly- conveyed from vendor site to customer site. A new business model is needed. But this paradigm switch is still ignored: FPGAs do not repeat the RAM-based success story of the software industry. There is not yet a configware industry, since mapping applications onto FPGAs mainly uses hardware synthesis methods.

    From a decade of world-wide research on Reconfigurable Computing another breed of reconfigurable platforms is an emerging future competitor to FPGAs.  Supporting roughly single bit wide configurable logic blocks (CLBs) the  mapping tools are mainly based on gate level methods - similar to CAD  for hardwired logic. In contrast to this fine-grained reconfigurability,  the Reconfigurable Computing scene uses arrays of coarse-grained  reconfigurable datapath units (rDPUs) with drasticallyreduced  reconfigurability overhead: to directly configure high level parallelism.

    But the “von Neumann” paradigm does not support soft datapaths because “instruction fetch” is not done at run time, and, since most reconfigurable computing arrays do not run parallel processes, but multiple pipe networks  instead. To introduce the new business model to cope with the current accelerator design crisis a transition from CAD to compilation is needed,  and from hardware/software co-design to configware/software co-compilation.  The paper illustrates such a roadmap to reconfigurable computing, supporting the emerging trend to platform-based SoC design.

    A Decade of Reconfigurable Computing:
    A Visionary Retrospective [p. 642]

    Abstract: The paper surveys a decade of R&D on coarse grain  reconfigurable hardware and related CAD, points out why this emerging discipline is heading toward a dichotomy of  computing science, and advocates the introduction of a new soft machine paradigm to replace CAD by compilation.
