Abstract

There are several shortest-path search algorithms such as A-star, D-star and Dijkstra. These algorithms are widely used in automotive vehicles and mobile navigation systems. As the number of nodes is increased considerably, the shortest-path algorithms implemented in software produce heavily computational overhead. In this paper, in order to avoid computational overhead, we propose a hardware model of the A-star algorithm for the shortest-path search engine. Especially, we propose shift register based on efficient hardware model and show simulation results in comparison with previous works.
