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
