| Research Abstract |
Practical packages of Computational Fluid Dynamics, UPACS and FaSTAR are accelerated by implementing on FPGAs. For UPACS, the execution speed of subroutines with complicated memory accesses was improved by 5 times to 20 times as the software execution on a PC. By using the partial reconfiguration, the number of utilized FPGAs and consumed power were reduced. For FaSTAR, an Out-of-order mechanism which reduces the number of stalls caused by treating unstructured mesh to only 1% was proposed and implemented. Tools for supporting such designs were also developed.
