Encyclopedia > TRON Project

TRON is an open real-time operating system kernel, and is an acronym for "The Real-time Operating System Nucleus". The project was begun by Prof. Dr. Ken Sakamura of the University of Tokyo in 1984. The project's goal is to create an ideal computer architecture and network, to provide for all of society's needs. A real-time operating system (RTOS) is a class of operating system intended for real-time applications. ... In computer science the kernel is the core of an operating system. ... Acronyms and initialisms are abbreviations formed from the initial letter or letters of words, such as NATO and XHTML, and are pronounced in a way that is distinct from the full pronunciation of what the letters stand for. ... An operating system is a special computer program that manages the relationship between application software, the wide variety of hardware that makes up a computer system, and the user of the system. ...

In computer science, computer architecture is the conceptual design and fundamental operational structure of a computer system. ...


As of 2003, the TRON system (or more specifically the ITRON derivative) is the world's most used operating system, being present in millions of electronic devices. The operating system is mainly used by Japanese companies, although interest in its use is growing worldwide. However it has been said that there is much misinformation in the English speaking world about TRON due to majority of the documentation being in Japanese [1]. 2003 (MMIII) was a common year starting on Wednesday of the Gregorian calendar. ...

The TRON architecture

TRON itself does not specify the source code for the kernel, but instead is a "set of interfaces and design guidelines" [2] for creating the kernel. This allows different companies to create their own versions of TRON, based on the specifications, which can be suited for different microprocessors. The specification of TRON is open, but the code generators are not required to make their source free unlike with the GNU General Public License. The TRON project permits the source to be protected and closed from the standpoint of intellectual property. Microprocessors, including an Intel 80486DX2 and an Intel 80386. ... The GNU logo The GNU General Public License (GNU GPL or simply GPL) is the most popular free software license, originally written by Richard Stallman for the GNU project. ... Intellectual property (IP) refers to a legal entitlement which sometimes attaches to the expressed form of an idea, or to some other intangible subject matter. ...


Sub-architectures

The TRON framework defines a complete architecture for the different computing units:

  • ITRON (Industrial TRON): an architecture for real-time operating systems for embedded systems; this is the most popular use of the TRON architecture
    • JTRON: a sub-project of ITRON to allow it to use the Java platform
  • 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. MTRON=DOKODEMO computer=computing-everywhere=HFDS(:Highly Functionally Distributed System) in 1984 by SAKAMURA Ken in Japan ->ubiquitous computing in 1988 by Mark Weiser in Europe and America.

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. 1984 (MCMLXXXIV) was a leap year starting on Sunday of the Gregorian calendar. ... This article is about the year. ... The initials NEC may stand for: NEC Corporation, a multinational corporation formerly known as Nippon Electric Co. ... 1986 (MCMLXXXVI) was a common year starting on Wednesday of the Gregorian calendar. ...

Fujitsu (富士通) is a Japanese company specializing in semiconductors, computers (supercomputers, personal computers, servers), telecommunications, and services, and is headquartered in Tokyo. ... Mitsubishi Electric is a manufacturer of video and audio equipment. ... Hitachi, Ltd. ... Microprocessors, including an Intel 80486DX2 and an Intel 80386. ...


Administration

The administration of the TRON Project, in its role to define TRON (the name of the specification itself), is by the TRON Association.
