Analogical reasoning technique is significant to the development of AI systems. Computing systems based on conventional architecture are very inefficient in doing analogical reasoning and this abstract the research and application of analogical reasoning. To solve this problem, a high -performance embedded analogical reasoning systems called ARC(analogical reasoning coprocessor) is presented in this paper. Since ARC has a specialized architecture with special speedup strategy to support analogical reasoning mechanism, and is implemented with advanced integrated devices, it’s much faster than conventional computing systems in doing analogical reasoning.
