 | SCORE Overview |
| Ada95 Cross Development Systems for PowerPC |
| ANSI-C Cross Development Systems for PowerPC |
| Multi Language Debugger |
| SCORE Graphical User Interface |
Multi-language: Ada 95 and C
Multi-host and multi-target
Risk reduction through reuse
Common native and cross development environment
No major rewrite of application
Shorter time to market for new applications
Built on open standards (Ada, C, ANDF, ELF, DWARF)
Coexistence with ANDF tool chain
Generates ELF compatible code
Robust, proven compiler technology
Multi-language symbolic debugger
Debugger can handle programs written in a mixture of C and Ada
Ada-like or C-like debugger commands
May be used stand-alone or within the SCORE environment
Debug compiler-optimized code
Code compiled without debug may be debugged at the machine level
Excellent run-time performance
Support for multiple target platforms
Point and click, easy-to-learn GUI
Command-line interface
Fast edit-compile-link-debug cycle
Fast ethernet downloading
Preconfigured for common target boards
Certifiable run-time (with tasking)
Very compact and efficient ROMable code
The SCORE multi-language debugger offers a full-featured,
multi-windowed, non-intrusive debugging environment
accessible from the SCORE GUI or the command-line. The MLD is a
symbolic debugger which supports the debugging of
Ada, C, or mixed Ada and C language applications. Seamless
transition between languages provides symbolic debugging
in a syntax that is familiar to a programmer in that language. In
addition, the MLD fully supports machine level debugging
including access and modification of memory and registers.
Define start-up scripts

The SCORE compilers from DDC-I provide:
| Interface data and functions between languages |
| Extensive diagnostic messages |
In addition, the Ada compiler offers:
Successfully validated under ACATS 2.2 (formerly ACVC) Full
Chapter 13 support including:
- Representation clauses
- Machine code insertions
Interrupt handling using protected procedures
No implicit heap usage
Support for DDC-I implementation defined pragmas
Support for:
- Annex A - Predefined Language Environment
- Annex B - Interface to Other Languages
- Annex C - Systems Programing
- Annex D - Real-Time Systems
- Annex H - Safety and Security
The SCORE system offers an Ada run-time system (RTS) and C run-time libraries which support:
| Pre-emptive priority scheduling |
| Fast scheduling |
| Scalable (several RTS variants included) |
| Configurable to custom hardware |
Ada RTS
- Task scheduling policies
- Queuing policies
- Priority
The SCORE environment includes C libraries which support execution
on target platforms.
The SCORE Ada library manager supports:
Flexible library structure
Library unit inspection tools
Program unit preservation over program lifetime
Automatic recompilation of obsolete program units
Flexible Project Management
SCORE supports both large scale and small scale projects via:
Project, program, file, and user-level options
Automatic program recompilation
Additional Tools
The SCORE environment includes a collection of additional tools to
supplement the development of safety-critical,
object-oriented, real-time, embedded applications:
GUI
Assembler
Disassembler
Object tools
Stand-alone ethernet and serial downloaders
User controllable linker
Extensive documentation is provided:
| User's guide for all tools |
| Installation guide |
| On-line help |
| Getting started guide |
| Extensive compile time diagnostics |
| Release notes |
