of computational units could be efficiently
constructed.
At the time this research was conducted,
there were many uses for FPGAs and most
of them had nothing to do with high-performance
computing (HPC). Examples of
non-HPC applications for FPGAs include
the following:
* Replacing application specific integrated
circuits (ASICs) in a design in an attempt
to reduce the time to market.
* Replacing ASICs in a low volume product
in an attempt to save money (ASICs
are cheaper, but only when ordered in
quantity).
* Temporarily replacing ASICs (or possibly
even the processor itself) during the
design phase of a project. This makes it
easier to test out the merits of alternative
designs before committing to one.
* Accelerating applications that are primarily
composed of a large number
of bit manipulations, including signal
and image processing and cryptography,
which can all be HPC applications
under the correct circumstances.
* Simulating networks, which would otherwise
be an HPC application.
* Simulating ASICs prior to their production.
It
was determined that FPGAs may be
applied to HPC applications in the following
distinct ways:
* The acceleration of bit manipulations (as
just mentioned)
* Integer calculations
* Fixed-point (i.e. decimal) calculations
* Floating-point calculations using dedicated
adders, multipliers, and/or fused
multiply-add units. These may be
formed entirely from reconfigurable
cells, or they may be formed from DSP
slice technology combined with glue
logic created out of reconfigurable cells.
* Floating-point calculations using soft
implementations of embedded microprocessors.
