Reconfigurable and Parallel Architecture for Browsing Genomic Databases


Scanning the genomic database is a common task, daily performed by thousands of researchers for extracting new knowledge from this huge amount of data. Today, this represents tens of Gigabytes. Tomorrow, according to the genomic data exponential growth, the volume of information to manipulate will reach Terabytes.

RDisk System

We propose a 48 parallel disk system whose originality is to attach reconfigurable computation capabilities near the disk for providing on-the-fly data filtering. Speed-up is provided both by accessing tens of disk in parallel and by hardwiring efficient FPGA filters.
