JAPAN'S HOMEGROWN OPERATING SYSTEM
TRON Competes for the Info-Appliance Market (May 22, 2003)
TRON stands for The Real-Time Operating System Nucleus. It is a computer operating
system from Japan that was thought up by Professor Ken Sakamura of the University of Tokyo in 1984. Sakamura has been a pioneer of
the idea of "ubiquitous computing," in which tiny semiconductor chips
are embedded in every product, enabling computers to monitor situations and to
support people in their daily lives without specific prompting. In simple terms,
this concept means having computers everywhere.

TRON Already Used in Cellphones, Digital Cameras
What distinguishes TRON from other operating systems like Windows is the extremely
high speed at which data is processed and the fact that the source code is freely
available. These are just two of the reasons why TRON is installed in most Japanese-made
cellphones and digital cameras, as well as in many other electronic products,
such as audio-visual devices, rice cookers, air conditioners, fax machines, karaoke
machines, and car-engine control devices. The mini-computers fitted to these devices
are called embedded chips, and about 5.3 billion of them are produced worldwide
each year. It is thought that about half of these run on TRON. Since only about
150 million PCs are shipped each year, these figures mean that TRON is used in
far more machines than the overwhelming leader in the personal computing market,
Microsoft's Windows OS. In fact, in terms of machine numbers TRON is the most
widely used OS in the world.
Recently it is TRON's open-source status that has been attracting attention. Microsoft
has never revealed the source code - the blueprint - for Windows, insisting that
it is a corporate secret, and has refused to allow others to adapt its OS as they
wish. For this reason, the inner workings of Windows have remained a mystery,
and some public institutions and corporations have complained at not knowing what
is inside the OS. The lack of transparency even led the Chinese government and
some public organs in Europe to worry that state secrets might be vulnerable to
leaks when held on Windows machines. Some of them have therefore started to switch
to the open-source Linux OS developed by Finnish programmer Linus Torvalds instead.
TRON Set for Use in Info-Appliances
In Japan, the E-Life Strategy Research Group, an independent group formed by the
Ministry of Economy, Trade, and Industry's Commerce and Information Policy Bureau
and whose members include the president of a major electronics maker and university
professors, agreed in March that Linux or TRON should be used in info-appliances
(electrical appliances that are connected to the Internet). METI and Japanese
electronics makers are keen to move away from Windows and to nurture a homegrown
OS in order to secure a leading position for Japanese firms in the info-appliance
market. Info-appliances bring to mind images of such products as the air conditioner
that switches itself on as you come home from work and the fridge that orders
a delivery of beer from the liquor store when your stock runs low.
Meanwhile, Microsoft has decided to reveal its source code to government organs
and others, providing certain conditions are met. It has also announced that it
will make the source code for Windows CE, its OS for info-appliances, freely available
and will not object to manufacturers or others altering Windows CE or selling
products installed with an adapted version. Some see these moves as a response
to the success of Linux and TRON.
Having started life as the invention of a university professor, TRON seems to
have a bright future in cutting-edge electronics for the twenty-first century.
