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
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
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
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.
