Configware heading for mainstream
  • Configware market taking off for mainstream
  • FPGA-based designs more complex, even SoC
  • No design productivity and quality without good
    configware libraries (soft IP cores) from
    various application areas.
  • FPGA vendors and a growing no.
    of independent configware houses
    (soft IP core vendors)
    and design services .

5
OS for PLDs
  • separate EDA software market, comparable to the
    compiler / OS market in computers,
  • Cadence, Mentor, Synopsys just jumped in.
  • lt 5 Xilinx / Altera income
    from EDA software
  • Alliances with hundreds of partners providing
    hundreds of IP cores, synthesizable (hopefully)
    (WWW sites difficult to
    navigate)

  • 2-dimensional memory space
  • Supports generic scan patterns
  • Subject of parallel access transformations
  • compare Francky Cathoor et al .
  • Supports visualization

    Cathoor et al.
  • High Performance Memory Communication
    Architectures Herz
  • Custom Memory Management Methodology Cathoor et
    al
  • Data Reuse Transformations Kougia et al.

33
Processor Memory Performance Gap
von Neumann bottleneck
34
rDPAs classical cache does not help
  • super pipe networks, no parallel computers !
  • Stream-based arrays are a memory bandwidth problem
  • the memory bandwidth problem is often more
    dramatic then for microprocessors
  • classical interleaving is not practicable, since
    based on sequential instruction streams
  • classical caches do not help, since instruction
    sequencing is not used
  • the problem throughput of parallel data streams,
    not instruction streams

35
Cache does not help ....
however, the anti machine has no v.N. bottleneck!

58
Confusing Terminology
  • Computer Science and EE as well as ist RD and
    applicatgion areas suffer from a babylonial
    confusion.
  • Communication not only between Computer Science
    and EE, but also between ist special areas, even
    between ist different abstraction levels is made
    difficult mainly because of immature
    terminology in relation to reconfigurable
    circuits and their applications.
  • Terms are rarely standardized and often used with
    drastically different meanings even within then
    same special area.
  • Often terms have been so badly coined, that they
    are not self-explanatory, but misleading. A
    demonstratory example is the comparizon of terms
    used used in VHDL and Verilog.  
  • Ideal are "intuitive" terms. But often Intuition
    yields the wrong idea. Whenever a new term
    appears in teaching, I often have to tell the
    students, that the term does not mean, what he
    believes.
