Abstract
The alignment of many short sequences of DNA, called reads, to a long reference genome is a common task in molecular biology. When the problem is expanded to handle typical workloads of billions of reads, execution time becomes critical. In this paper we present a novel reconfigurable architecture for minimal perfect sequencing (RAMPS). While existing solutions attempt to align a high percentage of the reads using a small memory footprint, RAMPS focuses on performing fast exact matching. Using the human genome as a reference, RAMPS aligns short reads hundreds of thousands of times faster than current software implementations such as SOAP2 or Bowtie, and about a thousand times faster than GPU implementations such as SOAP3. Whereas other aligners require hours to preprocess reference genomes, RAMPS can preprocess the reference human genome in a few minutes, opening the possibility of using new reference sources that are more genetically similar to the newly sequenced data.
