TRON Real-time OS Family Honored as an IEEE Milestone
In May 2023, "TRON Real-time OS Family" was recognized as an IEEE Milestone by the Institute of Electrical and Electronics Engineers (IEEE) 1).
The IEEE Milestone program honors significant historical achievements in the extensive field of electrical and electronic engineering, particularly those groundbreaking innovations that, having been made public at least 25 years ago, have contributed significantly to the development of society and industry.
The subject of this Milestone is the "TRON Real-time Operating System Family, 1984." Proposed in 1984 under the guidance of Ken Sakamura (then a research assistant) at the University of Tokyo, TRON Project aimed at future computer applications, resulting in the proposition of ITRON Specification OS, CTRON, BTRON, and MTRON 2). Among these, the ITRON real-time OS (RTOS) specification was first proposed in 1984, and the OS implementing this specification has been widely used. These systems continue to improve and evolve. TRON Forum has announced and released many versions, including the T-Kernel, the compact µT-Kernel, the multi-processor AMP T-Kernel, and the SMP T-Kernel. The current IEEE Milestone encompasses the entire group of these RTOSs (Fig.1).

The IEEE Milestone is one of the most prestigious awards within IEEE, and it is customary for the commemorative plaque to be presented in a ceremony attended by the IEEE President (or a former or future President). On October 14, 2023, a plaque presentation ceremony was held at the campus of the University of Tokyo, with the participation of the IEEE President-elect, Dr. Thomas M. Coughlin, and the plaque has been placed in a place accessible to the public.
The history of the IEEE Milestone
IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. IEEE and its members are trusted in a wide range of fields, from aerospace systems, computers, and telecommunications to biomedical engineering, electric power, and consumer electronics, through frequently cited publications, international conferences, standards, and professional and educational activities.
There are numerous achievements around the world that have been recognized as IEEE Milestones. Among the older ones is the letter published by Benjamin Franklin in the Royal Society, which described his use of kites to study lightning in the 1700s. After World War II, the invention and mass production of transistors and the invention of radar were also recognized. In the IT field, recognized Milestones include the Intel 4004, Ethernet, Xerox Alto, Apple I/II, and Apple Macintosh computer. There are also many Milestones that reflect the breadth of fields IEEE deals with, such as in power generation and satellite communications 3).
In Japan, over 40 achievements, including QR Codes, the Mount Fuji Radar System, and the Shinkansen (Bullet Train), have been recognized. These recognitions showcase the industrial strength of Japan's electrical and electronics sector over the past 100 years, especially the momentum of the electrical and electronics industries after the war 4).
The TRON RTOS Family has also been recognized as having similar significance to these achievements.
The IEEE Milestone is evaluated and accredited by a committee called the IEEE History Committee.
TRON Project, which began in 1984, meets the condition of having a history of over 25 years. Therefore, in the summer of 2022, TRON Forum, in collaboration with Professor Emeritus Tomohiro Hase of Ryukoku University, began preparing the necessary application document as specified by IEEE. The final version of these document is available on the IEEE History Committee website 5).
After the application is submitted, the History Committee appoints an Advocate, who will ask for peer review, conduct further interviews if necessary, and submit a final report to the History Committee, which makes a decision on suitability.
We are very grateful to Mr. Robert Colburn (Milestone Administrator), who was the contact person for the History Committee, and Dr. Sergei Prokhorov (Chair of IEEE Computer Society Russia Chapter), who was the Advocate this time.

Afterward, Professor Sakamura gave a memorial speech. Following the ceremony, the attendees moved to the entrance hall on the first floor of the venue, where the plaque was unveiled by Professor Sakamura and Dr. Coughlin.
The ceremony was conducted entirely in English. This article quotes the greeting messages from the attendees and the content of the memorial speech.
(IEEE Tokyo Section Chair)
I'm truly delighted to celebrate this occasion with Professor Ken Sakamura, IEEE President-elect Dr. Thomas Coughlin and all of you.
The IEEE Milestone program was established in 1983 to honor significant innovations in the fields of electrical, electronics and information technology that have made considerable contribution to the advancement of the society and industry for at least 25 years. Until 2022, 237 Milestones have been recognized worldwide. Among them, these include achievements of the Benjamin Franklin's work and Volta’s electrical battery in the 18th century. Among those the 20th century innovations, many telecommunication fields, radio, television, semiconductors, computers, and the Internet were recognized.
The first Milestone presentation ceremony in Japan was held in 1995 at Tohoku University for the shortwave antenna, commonly known as the "Yagi Antenna." Until 2022, 40 Milestone have been recognized in Japan and 22 of them are in the Tokyo section area. And last week, the 41st Milestone in Japan was dedicated to Tohoku University for the invention of perpendicular magnetic recording. This was the area covered by the IEEE Sendai Section. TRON RTOS is the 42nd Milestone in Japan, and the 23rd in the Tokyo section.
Professor Sakamura at the University of Tokyo proposed TRON RTOS family in 1984. Its code is openly and freely available without any restriction. So it has been used in billions of devices such as industrial equipment, automotive devices, and household appliances. It plays an indispensable role in the IoT today. We consider it is truly an achievement worthy of Milestone.
Greetings by Guests of Honor
(Executive Director and Vice President, The University of Tokyo)
It is a great honor to join you to celebrate this significant IEEE Milestone, the recognition of the TRON real-time operating system. Our president Teruo Fujii conveys his warmest regards to all the guests gathered here today for this festive occasion. And I'd like to offer a greeting on his behalf.
The TRON Project is an industry academia cooperative effort initiated in 1984 by Dr. Ken Sakamura at the time a research assistant at the University of Tokyo. Based on a long-term vision, this project anticipated the arrival of the IoT era, and promoted development of RTOS for a wide variety of application scenarios. I understand that the RTOS is a system software that runs like a black box in home appliances, industrial equipment, automobile and many others. The TRON RTOSs have been adopted in wide range of products. It also aimed at the standardization of the technology. It is now widely used not only in Japan but also in many other countries.
I'm pleased to learn that such a basic technology for industry was born in our university about 40 years ago and is still evolving. I'm also happy that one of the largest professional organizations in the world, IEEE has recognized the impact of the technology on industry and recognized the technology as an IEEE Milestone. Besides, I'm very delighted that an IEEE plaque will be permanently displayed in our university building.
(IEEE President 2020)
The IEEE, the world's largest professional organization, has recognized TRON RTOS as a Milestone for its outstanding achievements. As you may know, for a technology to be recognized as a Milestone, it must have contributed to the industry and society for over 25 years.
Dr. Sakamura and I know each other for a long time. It has been more than 40 years. Perhaps it is good that we have both studied in different fields. I’m in robotics. He works in computer science, and promoted TRON Project. I invited him to give a talk at IEEE robot automation annual conference in New Orleans 2004, because his talk is so fantastic. I have many fond memories with him. We have a mutual student, and I’ve had the honor of giving lectures with the invitation of Professor Noboru Koshizuka. Dr. Koshizuka is one of the students of Dr. Sakamura. Our relationship has developed quite well.
I have truly enjoyed my relationship with Dr. Sakamura, Dr. Koshizuka and all of you here. I am so happy today because TRON RTOS has been recognized as the Milestone.
(Chair, IEEE Japan Council History Committee)
I can clearly state one thing on the occasion of this Milestone dedication. I must say that Dr. Sakamura’s great work is very good and successful invention. I hope that this TRON Project will achieve a great success.
It is my pleasure to participate in today’s IEEE Milestone dedication as we celebrate the innovative spirit and pioneering work undertaken by Professor Ken Sakamura and his computer architecture project team here at the University of Tokyo in the development of the TRON RTOS Family, which is now instrumental in billions of embedded consumer devices around the world.
Without delving into a detailed description of IEEE at this moment, I would like to discuss its legacy. IEEE’s legacy is a story of innovation and collaboration. Our founders came together in a spirit of cooperation to support the public with technological improvement. Among them were notable figures such as Alexander Graham Bell and Thomas Edison. And since 1884, when the American Institute of Electrical Engineers (AIEE), the predecessor of IEEE, was founded, IEEE has been fostering technical advancement for the benefit of humanity.
IEEE reflects nearly 140 years of being at the forefront of the technical revolutions in energy, communications, and computing; the underlying disciplines in hardware and software that have supported these technological advances and the many fields of application in industrial activities, consumer products, transportation, medicine, and many other domains that have shaped our modern standard of living. In fact, it will turn 140 years old in 2024.
The profession of engineering has a long, rich, and important history. And it is essential that our pioneering technological developments and discoveries, and the people behind them, such as Professor Ken Sakamura and his team at the University of Tokyo, are recognized and celebrated for generations to come.
As the largest technological association in the world, it is an important part of IEEE’s mission to preserve the legacy and heritage of our professions, to recognize great achievements, and to promote the importance and impact of engineering.
Since our inception, IEEE has had a standing History Committee that advises the IEEE Board of Directors on matters of the legacy and heritage of IEEE and its members and their related professions and technologies, and carrying out some activities in those areas.
The mission of the IEEE History Center, which celebrated its 40th anniversary in 2020, is to preserve, research, and promote the history of information and electrical technologies. The Center maintains many useful resources for engineers, students, historians of technology, and for anyone interested in the development of electrical and computer engineering and its role in modern society.
The Center plays an essential role in helping communities around the world understand how engineers, scientists, and technologists contribute to our global society and have contributed to building today’s technologically advanced world. One way they do that is through the IEEE Milestone program.
Funded by donations to the IEEE Foundation, the Milestone program recognizes great moments throughout our world’s long history of technical innovation. The program began in 1983 as part of IEEE’s Centennial Celebration. Today’s Milestone is our 240th worldwide and is the 23rd for the IEEE Tokyo Section.
IEEE Milestones help to increase the public’s understanding of the contributions to society made by electrical, electronics, and computer engineers, and the strides made by countless technologists as they sought to advance technology to benefit humanity.
Milestones are also a way for members in IEEE Sections to take pride in their profession and its accomplishments. They demonstrate to their local community how engineers, scientists, and technologists have contributed not only to that community, but also to our global community, helping to build today’s technologically advanced world.
The TRON RTOS Family has always been open and free, an approach that has proven novel and powerful. Today, RTOS based on TRON specifications are used across the consumer electronics industry and beyond, from engine controls on automobiles, satellites, mobile phones, game consoles, and many other appliances.
Thank you very much for the opportunity to speak to you today.
Congratulatory message from the industry
(SEVP/CTO/Head of Software, eSOL Co., Ltd.)
It is my honor to be here to share with you some of eSOL’s successes using the TRON RTOS Family invented by Dr. Sakamura.
I started my career in the embedded software industry 28 years ago. One of my memorable projects as a young kernel developer was developing μITRON compliant real-time kernel for an SoC for DSC or digital still cameras designed by Texas Instruments Japan back then. It was one of the early SoC that contained ARM7TDMI, the first popular ARM processor IP and DSP. Our RTOS and Driver Stacks were at the core of their DSC/SDK. This was a huge success, and it was deployed in more than 100 million devices across many OEMs all over the world. And more than anything, this was not possible without Dr. Sakamura.
Ten years later, ARM developed its first symmetric multi-processing processor, ARM11 MPcore. We developed the first commercial operating system that supported ARM11 MPcore, both SMP and AMP, based on an open source T-Kernel. Based on this, NEC Electronics back then developed a series of SoCs for automotive car navigation system. Our operating system supported all of them. This was another huge success, deployed in millions of vehicles across the world. And, more than anything, this was not possible without Dr. Sakamura.
Now, computer technology has become more crucial than ever, meanwhile Japanese manufacturers not only the automotive ones, but also other industries face huge challenges. Their devices now need to transform into software defined intelligent devices.
I believe we can overcome the challenge with what we have learned from Dr. Sakamura. Congratulations Dr. Sakamura.
IEEE Milestone Acceptance Speech
I am honored to receive the IEEE Milestone for TRON Real-time Operating System Family, 1984.
TRON Project which has produced the TRON Real-time OS Family, 1984 is into its 40th years of operation today. The project name, TRON, stands for The Real-time Operating system Nucleus. And as the name suggests, it started as a project to create a real-time OS for then emerging 16-bit microprocessors. The TRON Real-time OS Family, 1984 is still used and being improved and maintained.
A real-time OS should be small and compact, which is why today's ceremony is kept small and compact as well.
Today, I would like to thank IEEE and its History Committee to recognize the TRON RTOS Family, 1984 as an IEEE Milestone. This is appreciated by all the members, present and past, who have been involved in TRON Project in creating and maintaining the OS family.
Personally, earlier this year, I have received another prestigious IEEE award, Masaru Ibuka Consumer Technology Award. I feel very delighted that my leadership of TRON Project over the last 40 years is now recognized this way by the award and now Milestone additionally.
2. Positioning of this Milestone
IEEE Milestones have recognized many achievements from the past. Some of them are easy to understand. For example, Ethernet, and Apple II computer, Television research in Hamamatsu, a Japanese city, and transmission of transatlantic radio signals in 1901. These are examples of easy-to-understand Milestones.
On the other hand, there are other Milestones that are hard for lay people to understand. For example, Enrico Fermi's Major Contribution to Semiconductor Statistics (1924-1926), Raman Effect (1928), Development of CDMA for Cellular Communications (1989), Our Milestone is in the latter category.
It may not be obvious to the lay people why the TRON RTOS Family, 1984 matters. It matters because it is used widely all over the world. The RTOSs of the TRON RTOS Family, 1984 is used in many devices, but in an invisible manner. It is different from desktop OS or smartphone OS which are familiar to many of us. For example, it is used in the following places and devices: automobile engine control, space probes and launcher rockets, household electronic appliances.
The developers and people who use the TRON RTOS Family know that they have created technological social infrastructure. However, it is not visible to ordinary people usually.
But IEEE Milestone is a spotlight that illuminates their achievements so far. So being recognized as an IEEE Milestone is very encouraging for them. And I am grateful for the recognition as the leader of TRON Project.
Let me explain a bit about TRON Project which has produced the TRON Real-time OS Family, 1984. This shall give some insight into why the TRON RTOS Family was created.
3. TRON Project
I said that the name stands for The Real-time Operating system Nucleus. The project started as a project to create a real-time OS for then emerging 16-bit microprocessors. It began in 1984, and has been going on for almost 40 years.
40 years ago, microprocessors were adopted to control many devices such as home electronic appliances and industrial equipment. Earlier, back in the 1970s, 4-bit microprocessor Intel 4004 had appeared.
The engineers of the era tried to use the microprocessors to control "things," "objects in our living sphere." That was the driving force to make microprocessors popular. It was not used as a general computer in the beginning.
Microprocessor is a very general device. Creating an application software that controls a specific device was the approach taken then. Before that, hardware control circuits, Programmable Logic Controllers were used. Microprocessors replaced them with the addition of application software.
However, the control software, the application, was difficult to create from scratch.
Trying to cope with the difficulty of creating application for automobile industry, aerospace, home electronic appliances, telecommunication industry, and other fields, engineers gradually realized that it would help them to create a whole application system by having an underlying OS.
One can create an application for each different control application above an OS.
Real-time OS vs general information processing OS
Here I should mention the difference between real-time OS and an OS for general information processing on desktop PC or servers.
- Priority-based scheduling vs. round-robin scheduling
Industrial application requires real-time OS. The essence of real-time OS is priority-based scheduling. This is very different from round-robin scheduling of general information processing OS.
- Scarce hardware resources for computers used for real-time control
While servers or desktop PCs for general information processing have many gigabytes of memory, computers used for real-time control often have only very limited memory and other hardware resources. Power-supply also is very limited. Many so-called embedded computers need to run on batteries for a long time.
- Reliability: simple is beautiful
When you consider the usage of software on space satellites, you must realize that it is not easy to fix
a software bug there. So the reliability must be high and testing the code should be easy in principle. So small compact OS is necessary.
These differences were behind the design of the first member of the TRON RTOS Family, 1984, namely ITRON-specification OS for RTOS. "I" in ITRON stands for Industrial control.
Companies such as NEC, Hitachi, Fujitsu, and others created OSs according to the specification, and there were many products that used such OSs inside. The usage expanded very quickly. Engineers who designed control application needed such real-time OSs.
Around this time, IEEE helped the project in many ways. For example, there was a special issue of IEEE MICRO that picked up TRON Project as a main theme. That was April 1987 issue (Fig.1). This helped us to disseminate the knowledge of the project including the project goal and the achievements so far.
We held symposiums to disseminate the technology. Springer-Verlag published the proceedings of the first few symposiums. Subsequently, IEEE Computer Society became the technological sponsor, and we published the proceedings via IEEE CS press. I would like to thank IEEE CS for the collaboration.
Furthermore, in 1997, IEEE CS Press published a book that combines the specification of µITRON 3.0 and a few introductory chapters (Fig.2). Back then, the technology dissemination took place using printed publication. Thus, this specification book from IEEE CS press helped the TRON RTOS Family to reach various corner of the world. I saw the book in many university libraries when I visited overseas cities to give speeches.
Also, I was the Editor-in-Chief of IEEE MICRO from 1999 to 2001 and thus I could interact with many people and could introduce TRON Project to many contacts.
5. Typical applications
Let me list well-known examples of usage of the TRON RTOS Family, 1984.
- Small hand-held devices such as CASIO digital cameras and mobile phones. Nikon digital cameras and a Samsung digital camera
- Large scale telephone switch PBX
- Automobile usage - Engine control
- Japanese satellites and rocket launchers
- Industrial control such as semiconductor manufacturing devices
- How its usage widened
For the last two dozen years, the usage widened thanks to the use of the Internet.
Figure 4 shows the countries and regions where somebody downloaded the source code of the TRON RTOS Family. From the beginning of the project, we adopted the philosophy of Open Architecture. This means that the specification of the OS family and the source code were made available. This is the "Open" approach.
This open approach was recognized by the Takeda Award (Fig.5). Richard Stallman of GNU project fame, and Linus Torvalds of Linux fame and I shared the Takeda Award for the open approach in the industry in 2001. Both Stallman and Torvalds contributed to the general information processing OS. I contributed to the development of widely used real-time OS instead.
7. Evolution of microprocessors
Microprocessors have evolved from 4-bit CPU to, 8-bit, 16-bit, 32-bit and finally to 64-bit CPU.
These days, a single chip contains a CPU and many other peripheral devices inside. They are called single-chip microprocessors. These CPU chips are used inside devices that are connected to the Internet.
That brings the topic of the IoT, the Internet of Things paradigm, up front. With the IoT application framework, many objects in our surroundings are connected to the computer network, the Internet.
The TRON RTOS Family now is being used increasingly in such objects that are connected to the network. For example, the TRON RTOS Family is now used inside network-enabled multi-function laser printers, RF modules inside the mobile phones, and many consumer electronic devices.
8. Geographical Expansion
Geographically speaking, the usage has moved from USA and Japan to countries like Korea, China, countries in Southeast Asia such as Vietnam, Singapore, Malaysia, and India. These countries are where electronic goods are now manufactured. So the TRON RTOS Family is now being studied and used there. There are textbooks that were translated into regional languages (Fig.6).
From the viewpoint of TRON Project, I am very happy to report that there are entities in Singapore, Malaysia and China who have learned the TRON RTOS Family and offered to help establish regional development centers. Here, again IEEE has helped TRON Project in a sense.
In 2018, IEEE Standards Association adopted 2050-2018, "IEEE Standard for a Real-Time Operating System (RTOS) for Small-Scale Embedded Systems" which is based on micro-T-Kernel 2.0 specification.
This adoption has given a momentum behind the TRON RTOS Family and people in various regions have come to study the TRON RTOS Family seriously.
9. The IoT edge node is not standalone
In the IoT application framework, the nodes are often called edge nodes. These edge nodes have to talk to the cloud services today.
The TRON RTOS Family is now being used for such IoT edge nodes like Figure 7. The preferred protocol is 6LoWPAN, a subset of IPv6 protocol. There is a 6LoWPAN stack that runs on the TRON RTOS Family.
TRON Project owes its existence to the supporting members. They are commercial enterprises, academic entities, and government labs.
The TRON RTOS Family, 1984 is not a glittering topic that attracts many people. But receiving the IEEE Milestone helps us to highlight its importance and this is very good for the moral of the engineers and for courting young generation to this specialized field of computing.
I would like to thank IEEE and IEEE History Committee for this honor and would like to extend my appreciation to all who helped the project over the years. I would also like to thank Professor Emeritus Tomohiro Hase of Ryukoku University and Mr. Chiaki Ishikawa of my office for submitting the Milestone application.
I have heard that there was guidance from various members of IEEE Tokyo Chapter, Prof. Isao Shirakawa and Dr. Toshio Fukuda, the former President of IEEE during application review process. I would like to thank them all. But I cannot list all of them.
Again, on behalf of the engineers who developed the TRON RTOS Family, 1984, I would like to express my sincere appreciation of receiving IEEE Milestone plaque recognizing the "TRON RTOS Family, 1984" today. So, this concludes my acceptance speech. Thank you very much.
