The ITRON Technical Committee in April 1998 started the µITRON4.0 Specification Study Group. Under it were formed three working groups, a Kernel Specification WG, Application Design Guidelines WG, and Device Driver Design Guidelines WG. They were joined somewhat later by the Debugging Interface Specification WG.
The objective of the Debugging Interface Specification WG is to standardize interfaces between a µITRON4.0-specification real-time kernel and debugging tools (debuggers, in-circuit emulators, logic analyzers, etc.). Such standards will eliminate the need for debugging tool vendors to provide separate support for each µITRON-specification kernel, shortening development time and reducing costs. For kernel vendors it will mean improved availability of a wide assortment of debugging tools, with large benefits for users as well.
After the initial meeting scheduled in February 1998, the working group is carrying on its discussions mainly through e-mail exchanges and is drawing up debugging interfaces.
The ITRON Technical Committee welcomes participation in both the µITRON4.0 Specification Study Group and the working groups by embedded systems engineers who are willing to contribute actively to these efforts. There is no fee for participation, but active contribution to the studies is a requirement. See the ITRON Web site for details on how to take part.
The product listed in the table was newly registered as an ITRON-specification product since the last issue of this Newsletter and up until December 1, 1998. The most up-to-date list of registered products is available from here.

Listed below are the publications prepared and issued by the ITRON
Technical Committee as of December 1, 1998. Each of the publications
below can be obtained directly from the sources indicated. The revised edition of the ITRON3.0 Standard Handbook incorporates
Ver. 3.02.02 of the specification. Changes made since the earlier
edition of the Standard Handbook (Ver. 3.00.00) as of Ver. 3.02.00 are
given in the ITRON Standard Guidebook 2. Subsequent revisions as of
Ver. 3.02.02 involve only organizational changes and additional
explanations, not affecting the technical contents. The ITRON-µITRON Standard Handbook is a one-volume compilation
of µITRON (Ver. 2.0) and ITRON2 specifications. Printed editions
are no longer available from Personal Media Corporation, but the
entire contents are available in PDF format at
the company's web site. The ITRON Standard Guidebook 2 deals primarily with µITRON3.0.
The earlier ITRON Standard Guidebook '92-'93 remains as a valuable
reference for use with the µITRON (Ver. 2.0) and ITRON2
specifications, even though the dates in its title are now past.ITRON-related Publications

The ITRON Technical Committee had an exhibit in the Embedded Systems Conference
(ESC) held at the San Jose Convention Center from Sunday, November
1 through Thursday the 5th. We also took advantage of this occasion
to hold the ITRON International Meeting '98 in a hotel near the trade
show site. The ITRON International Meeting '98 follows on the ITRON
Supporters' Meeting held the previous year, making this the second
ITRON-related conference to be held in the United States. The meeting
was therefore aimed at updating interested persons in the United
States on the status of the ITRON subproject, and introducing ITRON
specifications and related products developed mainly in the United
States. The meeting this time was sponsored with the cooperation of
The Open Group, which carries
on open standardization efforts. We also received support from the Japan External Trade
Organization (JETRO). A summary of the meeting is given
below. After lunch was served in the conference hall, James Farrell of the
TRON Association U.S.A. Liaison Office opened the meeting. The first
presentation was by Toshiba's Kiichiro Tamaru, ITRON Technical
Committee chairman, who gave an outline introduction to the ITRON
project along with recent developments. Then Hiroaki Takada, of the
TRON Technical Committee and Toyohashi University of Technology,
described the µITRON4.0 specification and the ITRON TCP/IP API
specification. Next, V. Joloboff of The Open Group gave a
presentation on his organization's work in bringing Java technology to
embedded systems. Joloboff also noted that The Open Group has built
and maintained conformance tests for the POSIX specifications, and he
expressed an interest in the conformance testing system developed for
the µITRON specifications. He was followed by ITRON Technical
Committee member Shoichi Hachiya of Aplix Corporation, who ended the
first half of the program with an introduction to the JTRON2.0
specification. After a short break, product introductions were given by seven
companies, most of whom develop ITRON-specification OS products or
supporting products in the United States. This part of the meeting
was then closed, following which a special session was presented by
Cygnus Solutions on the use of open source elements in embedded
systems. Cygnus in September 1998 announced its eCos OS as an open
source, royalty-free OS with an ITRON-specification API. This product
was also introduced and demonstrated at the session. The meeting was attended by approximately 80 persons, including the
presenters, ITRON Technical Committee members and The Open Group
members. Considering that this was only the second such meeting to be
held in the United States, these can be seen as satisfactory results.
One problem, however, was that the timing of the meeting overlapped
with the ESC trade show, in which many of the participants were also
busily involved. Moreover, the length of the meeting was deliberately
made short because of this, which meant each presenter had only a very
brief slot to work with. On the other hand, holding the meeting at
the time of ESC made it easier to attract participants. These factors
will need to be weighed carefully when the ITRON Technical Committee
plans a similar meeting for 1999. The ITRON Technical Committee took part in the ESC exhibit again
this year as well, publicizing the ITRON specifications. Initially we
planned to share a booth with Japan System House Association (JASA) as
we did the previous year. However, JASA pulled out of the exhibit at
the last minute, so we ended up exhibiting in our own booth. The
booth used panels to introduce the µITRON real-time kernel, the
ITRON TCP/IP API specification, and the JTRON2.0 specification.
Another panel listed the available ITRON-specification products. A
personal computer connected to the ITRON Web site rounded out the
booth. This year some 28 exhibitors cooperated by displaying placards
with the ITRON logo and the simple message, "We Support the ITRON
Project." Next year's ESC is scheduled to take place at the same San Jose
Convention Center, from September 26 through 30 (Sun.-Thu.). The
ITRON Technical Committee plans to take part in the next year's ESC
exhibit again.Report on ITRON International Meeting '98 and ESC Exhibit

The TRON Association introduced the ITRON specifications at the Microcomputer System and Tool Fair '98 (MST'98), held at Tokyo Big Sight from Wednesday, November 18 through Friday, November 20. In a symposium session at the MST'98 Conference, an ITRON special seminar was put on by the ITRON Technical Committee.
MST is a specialty trade show devoted to embedded systems technology and development support products, put on each November by the Japan System House Association (JASA). For the past two years it has been held at Tokyo Big Sight. The show has grown in size each year, with some 120 exhibitors at the latest edition. For the first time this year the show was produced in conjunction with Miller Freeman, sponsor of ESC described above.
The TRON Association booth made use of panel presentations, distribution of materials, and personal computer hookup to the ITRON Web site, as in previous years. In addition, copies of the October ITRON Special Seminar proceedings were on sale at the booth. Questionnaires for the annual survey on RTOS use trends were distributed, and when possible, visitors were surveyed on the spot. The now customary publicity means of asking other exhibitors to display ITRON support placards in their booth was adopted again this time, with 41 exhibitors responding to the request (see the list). We would like to thank each of these companies for their cooperation.
At MST '97, the ITRON Technical Committee for the first time ran a special seminar on embedded systems. This time an ITRON special seminar was held to introduce the latest developments in the ITRON project, centering around the µITRON4.0 specification now being drawn up. Details of the seminar are outlined below.
Even though a large hall holding 300 persons was reserved for the seminar, the attendance at each of the presentations was standing room only. Duly impressed with the strong interest in the ITRON Project, the ITRON Technical Committee is planning to hold similar seminars in the years to come.

Products recently registered with the ITRON-specification product registration system are introduced here.
The MR79 is a µITRON-specification real-time OS implemented for Mitsubishi Electric Corporation's 16-bit microcomputers in the 7900 series.
Implements the µITRON3.0 specification
Based on the µITRON3.0 specification, the MR79 OS supports all
Level R and Level S functions as well as some Level E functions.
A compact OS
The system calls used in the target system can be incorporated simply
by linking OS libraries, generating a system of the minimum necessary
size. The OS kernel size is a minimum of 2 Kbytes and maximum of
approximately 11 Kbytes.
Easy interrupt handler writing
Interrupt handlers are written simply as ordinary functions. To
register them in the system, only the number of interrupt sources and
the interrupt handler entry points need to be designated; the
necessary files are generated automatically by the cfg79 configuration
tool.
C language development support
Application development in C is supported by the supplied C language
interface library, for use with the NC79 cross-tool kit developed for
the 7900 series processors.
Comes with cfg79 configuration tool
Initialization of tasks, event flags and other OS resources is taken
care of by the cfg79 configuration tool supplied with the MR79. It
automatically generates the necessary configuration files for
registering system settings in the OS, based on a C-like configuration
file.
