FPGA hardware and tools (VHDL, Viva, MitrionC and CHiMPS) are described. FPGA performance is evaluated on two Cray XD1 systems (Virtex-II Pro 50 and Virtex-4 LX160) for human genome (DNA and protein) sequence comparisons for a computational biology code (FASTA). Scalable FPGA speedups of 50X (Virtex-II) and 100X (Virtex-4) over a 2.2 GHz Opteron were achieved. Coding and IO issues faced for hum...
