To realize secure and safe information communication environment, the authors are carrying out CUE (Coordinating Users' requirements and Engineering constraints) project and started to develop a data-driven chip-multiprocessor CUE-v3 for ad hoc and ubiquitous communication environment available even in the case of emergency. Since CUE-series data-driven… (More)
High speed message handling is one of the most important problems for ecient multithread processing. We have proposed a processor architecture called Datarol-II, that promotes the ecient ne-grain multithreaded execution, by performing fast context switching among ne-grain concurrent processes. We are developing a prototype multithread machine KUMP/D (Kyushu… (More)
High speed image and video processing is a key technology in multi-media applications, and, therefore, currently many hardware accelerators to speed up such processing are developed and used. However, for the next generation advanced multi-media applications in the next generation, such as high quality virtual reality, bidirectional visual interface, etc.,… (More)
Nearly complete gasification of organic compounds has been achieved by stoichiometrically insufficient amounts of RuO2 in supercritical water (SCW) to provide CH4, CO2 and H2, all the hydrogen atoms of which originate from water, and the catalytic effect of RuO2 results from a redox couple of Ru(IV)/Ru(II) induced by SCW.
