Introduction
TRON is an open real-time operating system kernel. TRON is an acronym for "The Real-time Operating system Nucleus". The project started by Prof. Dr. Ken Sakamura of the University of Tokyo in 1984. The project's aim is to create an ideal computer architecture.
History
In 1984 the TRON Project was officially launched, a year later in 1985 NEC announced the first ITRON implementation based on the ITRON/86 specification. In 1986 the TRON Kyogikai (unincorporated TRON Association) was established, Hitachi announced its ITRON implementation based on the ITRON/68K specification, and the first TRON project symposium is held. In 1987 Fujitsu announced an ITRON implementation based on the ITRON/MMU specification, Mitsubishi Electric announced an ITRON implementation based on the ITRON/32 specification, and Hitachi introduced the Gmicro/200 32bit microprocessor based on the TRON VLSI CPU specification.
Cyber Society
The TRON project assumes that we will see an advanced computerized society (a cyber society) in the near future. In cyber society, all of the devices, equipment and tools that we use in our daily lives have built-in microcomputers. Furthermore, a variety of different aspects of mankind's activities are supported by having these devices operate cooperatively by interconnecting them with computer networks. Devices with built-in computers and connected to networks are referred to as intelligent objects, and the whole system in which these objects are interconnected and operate cooperatively is called a Highly Functionally Distributed System (HFDS). The realization of HFDS is the most important goal of the TRON project.
Framework
The TRON framework defines a complete architecture for the different computing units:
- ""ITRON (Industrial TRON) and JTRON"" is an architecture for real-time operating systems for embedded systems.
- BTRON (Business TRON): for personal computers, workstations, PDAs, mainly as the human-machine interface in networks based on the TRON architecture
- CTRON (Central and Communications TRON): for mainframe computers, digital switching equipment
- MTRON (Macro TRON): for intercommunication between the different TRON components
As of 2003, the TRON system is the world's most used operating system, being present in millions of electronic devices.
The specification of TRON is open, but the code generators are not required to make their source free like GPL. The TRON project permits the source to be protected and closed from the standpoint of intellectual property.
