Abstract: This paper describes the acceleration of hmmsearch by exploiting fine-grained designs based on FPGA. It exploits data reuse schemes by making use of the method of fetching, slip windows and data transmition and utilizes pipeline in the matrix cell. Experimental results show the performance can reach to 3.6 GCUPS, which is nearly 235 speedup over that of CPU. One PE calculating performance improves 34% over the fastest FPGA accelerator of the same kind.

Key words: biological sequences search, accelerator, FPGA
