Unfolding Method for Shabal on Virtex-5 FPGAs: Concrete Results
Posted on July 28th, 2010 No commentsIn this paper, we focus on an optimized implementation of the Shabal candidate. We improve the state-of-the-art using the unfolding method. This transformation leads to unroll a part of the Shabal core. More precisely, our design can produce a throughput over 3 Gbps on Virtex-5 FPGAs, with a reasonable area usage.
