Advances in ITRON specifications-supporting multiprocessor and distributed systems

The design policies and overviews of the extended ITRON specifications supporting distributed systems and multiprocessor systems under investigation are described. Wide applicability and high run-time performance are primary goals of these extended specifications, which are realized by inheriting the design policy of the original specification that excessive virtualization of hardware should be avoided. The authors review the design policies of the ITRON specifications, and present how the policies are incorporated in the extended specifications. The extensions expand the application areas of ITRON and make important steps towards the realization of HFDS, which is the final goal of the TRON Project
