dards, language abstraction continues unabatrpretation of such high-level abstract languages requires high performance. The MP98 low-power, high-performance microprocessor architecture supports smart information terminals using the technologies of single-chip multiprocessor and low-voltage circuits. Its first prototype (code named Merlot) achieves 1 giga instructions/sec (GIPS) at 1 watt.3-5 In this article, we briefly describe the MP98 architecture from a viewpoint of software. Then, we realize several basic algorithms in artificial intelligence on our multithreaded Masato Edahiro Satoshi Matsushita Masakazu Yamashina Naoki Nishi NECCorporation MERLOT, THE FIRST MP98 ARCHITECTURE PROTOTYPE, PROMISES 1-GIPS
