Abstract: Analogical reasoning technique is significant to the development of AI(Artificial Intelligence) systems . Computing systems based on conventional architecture are very inefficient in doing analogical reasoning,which obstructs the research and application of analogical reasoning. To solve this problem, a high-performance embedded analogical reasoning system called ARC(Analogical Reasoning Coprocessor) is presented. Since ARC has a specialized architecture with special speedup strategy to support analogical reasoning mechanism, and is implemented with advanced integrated devices.It is much faster than conventional computing systems in doing analogical reasoning.
