The TRON (The Realtime Operating System Nucleus) Project is a new computer architecture that has been proposed for the creation of a new computer society. In the 1990s, it is expected that the age of one computer per person will come about. The TRON Architecture takes into account how to handle the relations between computers and people, and between computers and computers in that age. The proceedings of the Seventh TRON Symposium presented here cover all aspects of the TRON Project. ITRON (Industrial-TRON) for embedded computer systems, BTRON (Business-TRON) for workstations, CTRON (Central-TRON) for large file and communication servers, and CHIP (TRONVLSI microprocessor architecture) are described.
