Baltimore SIGAda will hold a meeting on Tuesday, March 14th at JHU/APL. A deli tray and soft drinks will be served at 7:00 PM. The program will begin at 7:30 PM. Topic: DDC-I's New Safety-Critical, Object-oriented, Real-time Embedded System (SCORE) Uses Open Standards Speaker: Joyce L. Tokar, Vice President of Technology Please RSVP to Charlene mailto:[log in to unmask] by noon Monday the week of the meeting if you plan to come for the deli tray so that we can quantify our order. Late RSVPs are also welcome, and you can always attend even if you have not RSVP'd. The web site provides directions http://www.jhuapl.edu/sigada/ Important Notice: Elections for new officers are coming in May. If you are interested in running for office, would like to nominate someone, or just help the chapter in some other way, please contact one of the current officers: Rush Kester, J.C. Morrison, Tom Panfil, or Maynard Priestman. See http://www.jhuapl.edu/sigada/officers.html for contact info. =================================================================== Title: DDC-I's New SCORE Ada System Uses Open Standards DDC-I has developed a new compilation system named SCORE (Safety-Critical, Object-oriented, Real-time Embedded) which supports both Ada95 and C. This new product line was built on several open standards: ANDF 4.0, DWARF 2.0, and OMI Host-Target Protocol. The central concept is ANDF 4.0 (Architecture Neutral Distribution Format) which is a new XOpen standard. ANDF is a low-level abstraction of high-level languages, rich enough to model all known program constructs. It is completely independent of target architecture (hence architecture neutral). A source program is translated into an ANDF representation by a language-specific producer. The ANDF representation is then translated into assembly or machine code by a target-specific installer. The second open standard, DWARF 2.0, is used by SCORE compilers to contain the diagnostic information for the SCORE multi-language debugger. Previous DDC-I debuggers relied upon proprietary formats which required access to the Ada program library. Using the DWARF format, all information needed to debug a program is contained within the object file. Although DWARF does identify the source language, its constructs are language-independent. The final standard is the OMI Host-Target Protocol. OMI is the Open Microprocessor Initiative within the European Community. The Host-Target Protocol defines the protocol the SCORE multi-language debugger uses to communicate with the debug monitors on the target boards. Speaker Bio: Joyce L. Tokar, Vice President of Technology for DDC-I world-wide, is responsible for the definition and development of technology and customer support. This includes the continued support of the existing product lines as well as the definition of new products and technical direction. Dr. Tokar is also responsible for quality assurance within the group. Dr. Tokar represents DDC-I on a number of industry panels, sessions and working groups. She heads the US delegation to the ISO Working Group focused on Ada. Dr. Tokar received a Certificate of Appreciation for Valuable Contributions to the Ada 95 Project, from the Office of the Secretary of Defense. She was received the 1994 Duncan Peddie Memorial Lecturer Award from the University of Natal. And she has received an ABI Distinguished Leadership Award. --------------------------------------------------------------------------- We will have copies of the NOV 1998 Walnut Creek "Ada and Software Engineering" dual CD-ROM set available for sale to attendees at out $10 cost.
