An improved FPGA-based specific processor for Blokus Duo

This article presents a hardware design of a specific processor for Blokus Duo game. This design is an evolution of our previous work presented in the ICFPT´13 Design Competition. In order to improve its performance we have designed parallel hardware blocks to speed up the most time-consuming tasks, and included additional techniques to reduce the search space. As a consequence we can process a board six times faster than in our previous version and we prune the game-tree much more efficiently.
