Overview of our activities FPGA for high performance computing Montecarlo simulation Fingerprint matching Real time video compression of Formula 1 sensor data Motor control for wind tunnel equipment Intelligent cameras
FPGA for high performance computing (1/2) Dipole cubic lattice model – Energy calculation Montecarlo simulations need a lot of computation
FPGA for high performance computing (1/2) a lot of repeated, regular calculation high-performance VLIW style architecture
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
FPGA for high performance computing (2/2) Fingerprint matching need a lot of computation one new image vs. a big archive
FPGA for high performance computing (2/2) (band limited) phase only correlation algorithm correlation phase-only correlation
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)
Video Compression on F1 vehicle thermic camera to control tyre temperature normal b/w camera to control tyre deformation low band high noise channel between car and boxes
Video Compression on F1 vehicle need for real time on board video compression to decrease the amount of data to be transmitted some on board data elaboration
Video Compression on F1 vehicle Image and video acquisition/compression Temperature evolution of four tyres platform (with extra debug/develop as seen by thermic cameras features)
