FPGA-accelerated information retrieval: high-efficiency document filtering

By W. Vanderbauwhede, L. Azzopardi and M. Moadeli


Power consumption in data centres is a growing issue as the cost of the power for computation and cooling has become dominant. An emerging challenge is the development of ldquoenvironmentally friendlyrdquo systems. In this paper we present a novel application of FPGAs for the acceleration of information retrieval algorithms, specifically, filtering streams/collections of documents against topic profiles. Our results show that FPGA acceleration can result in speed-ups of up to a factor 20 for large profiles
