SLIDE 5
FPGA for high performance computing (1/2)
Our current architecture features a speedup of 2
compared to a 3GHz Pentium 4 processor
The 1S40 FPGA can host 2 accelerator, bringing
the speedup factor to 4
Using the more recent Stratix II or Stratix III the
achievable speedup can be even greater
This way is possible to build up an accelerator
cluster whose cost/performance ratio is much smaller than that obtainable with a cluster of PCs

Fingerprint matching need a lot of computation
FPGA for high performance computing (2/2)
one new image vs. a
big archive

(band limited) phase only correlation algorithm
FPGA for high performance computing (2/2)
correlation phase-only correlation
SLIDE 8
A little spin-off: high performance DFT on FPGA
commercial solutions are not satisfying (too
slow, big or inaccurate)
butterfly algorithm (created for parallel
implementations)
different attempts (fixed vs floating point, data
size, etc.)
better than ALTERA FFT Core and other
commercial products (using our application- specific metric)
