Magazine features Ada success on AN/BSY-2 and Seawolf-class submarine

In the October issue of Defense Electronics, "Going to Sea With Ada" documents the advantages and lessons learned about the Ada programming language in large embedded applications. The AN/BSY-2 is a large Ada-based Submarine Combat System (SCS), built by Martin Marietta, and the its developers believe that Ada is critical to the success of large, extensive, embedded systems.

The AN/BSY-2 SCS program began full scale development in 1988, and when completed in 1995, will comprise 120 different computer programs. These programs will contain more than three million lines of unique Ada code, with code reuse bringing the total AN/BSY-2 software to nearly five million Source Lines of Code (SLOC). A subset of the AN/BSY-2 SCS is the AN/BQG-5 (WAA) sensor system for the SSN 688 Seawolf-class submarine, which has been delivered to the U.S. Navy and has successfully completed performance evaluation. The AN/BQG-5, totalling more than one million SLOC, is operational, and is considered one of the best passive sonar systems in the Navy's submarine force. Reprints of the article are available from the AdaIC.

Ada cover story for Embedded Systems Programming

"Ada Achieves Orbit" was the title of November's Embedded Systems Programming magazine. Inside the magazine, one feature article told why Ada was chosen for a satellite system; another provided a technical discussion about Ada's advantages for reuse, prototyping, and system design.

Educator's CD-ROM

Responding to the need for easily accessible educational resource materials and courseware, the Ada Joint Program Office developed a CD-ROM for "best of breed" Ada courseware. This is currently being updated for Ada 9X, and is expected to be available in March 1995. There is no charge for the CD-ROM. To get on the list to obtain a copy, contact the AdaIC.

Ada 's new logo

A new Ada logo, combining the globe symbol used by the AdaIC and the tagline: "Ada- The Language for a Complex World," has been approved for industry use in Ada marketing materials by Christine Anderson, Ada 9X Project Manager, and AJPO Chief Donald Reifer.

On the Internet, the new logo is available for downloading in .gif format from the public/graphics directory on the AdaIC's Internet host.

Mathis new Executive Director of Ada trade association

The second director of the Ada Joint Program Office is the first executive director of the Ada Resource Association. The ARA (formerly the Ada Software Alliance) named Robert F. Mathis of Columbus, Ohio, to the post on Nov. 7, 1994. Dr. Mathis brings to the job experience in each of the three segments of the Ada community: academia, government, and industry. He has been convener of the ISO's Ada working group since 1983.

SIGAda opens WWW server

The Association of Computing Machinery's Special Interest Group on Ada (ACM SIGAda) now has a World Wide Web (WWW) server. Point your WWW browser (e.g., Mosaic) to SigAda's URL: to access information on SIGAda Working Groups, and meetings, as well as Executive Committee minutes and action items.

Paige reaffirms Ada commitment, receives SIGAda award at TRI-Ada

In his keynote speech at TRI-Ada '94, the Hon. Emmett Paige, Jr., assured attendees that he is 100% behind the Ada program. His remarks summarized the progress the Ada program has made over the last year. The retired Army Lieutenant General's service and his support for Ada go back long before his current position as Assistant Secretary of Defense for Command, Control, Communications and Intelligence. To thank him for his dedicated service, TRI-Ada's hosts, ACM SIGAda, presented Mr. Paige with an Ada Achievement Award.

New report available on how Ada mixes with real-time research

The December issue of Embedded Systems Programming features an article on how Ada mixes with real-time research. Written by Svend Bodilsen of DDC-I, "Scheduling Theory and Ada 9X" is intended to bring the reader up to date on recent developments in scheduling. The article establishes a common framework from which to review the most important scheduling theories, including their analytical characteristics and limitations. Bodilsen's article looks at the implications of the different scheduling theories on system development and possible Ada 9X implementations. He closes by presenting the basic functionality of a toolset required to obtain the basic timing information needed to make the analysis of realistic systems practical.

Walnut Creek upgrades CD-ROM

There's an enormous amount of Ada information on the Internet, and vendors are offering it on CD-ROM. One company, Walnut Creek CD-ROM has just updated its "Ada CD-ROM" to a two-disk set. The price is $39.95, and it contains over 560 Mbytes of documentation, information, and source code _ including such items as the AdaSAGE development system, the Ada 9X GNAT compiler, and the entire Public Ada Library.
