ITRON Committee welcomes new members

The ITRON Committee has been joined by two new observer members, Sennet, Inc. from July and Accelerated Technology Incorporated from August. See the ITRON Web site for a complete, up-to-date list of ITRON Committee members.

Sennet, Inc.

A young company established in January 1999, Sennet is attempting to make the BTRON-specification OS more of a household word all over the world. One of the means to this end is by developing and marketing English-language and Chinese versions of Personal Media's B-right/V OS. The company is also developing its own original, scalable BTRON-specification OS. Its interest in the ITRON kernel stems from the expanding use of non-PC information appliances and from the wishes of customers. Taking advantage of the ITRON real-time response, Sennet is working to fulfill its grand vision of making the ITRON shell a standard platform that will someday become a worldwide de facto standard.

ITRON Open Seminar Report

The ITRON Open Seminar took place on July 4 and 5 (Tuesday and Wednesday) at Tokyo Big Sight (Tokyo International Exhibition Center) and Tokyo Fashion Town Building, both in Ariake, Koto-ku, Tokyo. The ITRON Open Seminar is an annual event introducing the latest news about the ITRON specifications, including their implementations and application, as well as development tools being made available. This year's seminar, held over two days as in the previous year, centered on the µITRON4.0 specification and related specifications.

The overall organization of the seminar was much like last year's, with the first day introducing recent trends in the ITRON project and the second day getting into detailed technology. This year the second day of the seminar also took up the ITRON Debugging Interface Specification and results of the JCG project development. The first day was attended by 160 persons, while the second day drew 110 participants, both excellent turnouts for a seminar of this nature.

Summary of Day 1 Seminar

The first-day seminar started out with updates on activities taking place in the ITRON Project. The morning sessions presented results of the yearly survey on RTOS use trends, outlined the ITRON debugging interface specifications, and gave introductions to the device driver design guidelines, the µITRON4.0 validation specification, and C++ API specification studies.

The afternoon session began with a panel discussion on the use of upstream design tools in real-time and embedded systems, as well as the involvement of the ITRON Project in such tools, which are expected to assume growing importance. It was followed by six brief presentations introducing development tools supporting products and operating systems adopting the ITRON specifications, or illustrating ITRON-specification OS application in actual development cases. The opening day was capped off as in previous years with a special guest speech by TRON Project leader Ken Sakamura.

In parallel with the seminar was a small-scale exhibit introducing related products. A reception at the end of the day gave participants a chance to mingle informally.

Date: Tuesday, July 4, 10:00 a.m. to 6:00 p.m. (reception following)
Place: Tokyo Big Sight Conference Hall, rooms 607-609 (Ariake, Koto-ku, Tokyo)

Summary of Day 2 Seminar

The morning session on the second day was devoted to the ITRON debugging interface specification. Participants were given copies of the provisional specification (Ver. 1.A0.00), made available just the previous day on the ITRON Web site. Presentations talked about the design policies and summarized the specification, gave details of the interface, and described the test implementation being used for evaluation.

The afternoon session introduced development results of the JCG project, which was completed in March of this year. The JCG project was aimed at implementing middleware that will enable consumer appliances running on a µITRON-specification real-time kernel to connect to networks. The tangible results of the project are being made available as free software. Seminar participants received a CD-ROM containing this software; they heard explanations of each program and how they are used.

Outside the conference room where the seminar was held, participants were able to view the evaluation system for the ITRON debugging interface specification, along with a demonstration of the software resulting from the JCG project. (This same demonstration was also given at the exhibit for the first day's seminar.)

Date: Wednesday, July 5, 10:00 a.m. to 5:00 p.m.
Place: Tokyo Fashion Town, 9th floor, room A (Ariake, Koto-ku, Tokyo)
10:00 a.m. to 12:00 noon ITRON Debugging Interface Specification
1:00 to 5:00 p.m. JCG Project Results

The ITRON Open Seminar has been held for a total of 11 times. Because a major committee reorganization will be taking place in the TRON Association for the coming fiscal year, and also because of the increasing opportunities for introducing the ITRON specifications outside these seminars, we are considering making this the final ITRON Open Seminar. There will still be seminars at various times for giving detailed expositions of ITRON specifications, in any case. The ITRON Committee welcomes your suggestions and feedback.

Finally, we would like to take this opportunity to thank the companies who gave their generous support to this year's seminar, as listed below.

Following an overview of the TRON Project given by Ken Sakamura, various TRON specifications were introduced as well as their application. Presentations covered the development of ITRON kernels and peripheral functions, the JTRON, BTRON and TRON-GUI specifications, and finally introductions to products implementing ITRON specifications and to the JCG project. Some 350 persons attended this event, far exceeding initial forecasts and demonstrating the high expectations for the TRON Project in Korea. The exhibit attracted large numbers of visitors seeking information about the products shown there. We hope this interest will translate into wider use of the ITRON specifications in Korea.

The success of this seminar has led to preparations being made to open a TRON Association liaison office in Korea. The TRON Association would like to hold additional such seminars in other parts of Asia.
