Gedae helps BAE Systems save time and money.
Edinburgh, Scotland. - June 12, 2003– ’
On January 15th, 2001 Gedae and BAE SYSTEMS announced an agreement allowing BAE to use Gedae for
development of the Captor Radar software.Two-thirds of the way through production the Captor Radar Program has
quantified the impact of Gedae on productivity and yielded improvements in the range of 4.1 to 4.8. This measurable
improvement has been defined as the Gedae Productivity factor or GPF.
The GPF is derived from the productivity gained between Tranche1 and Tranche 2 signal processing software development. An effort has been made to factor out the cost of change to Tranche 1 during its development.
The Tranche 1 Development Programme implemented the Captor signal processing functionality using Real-Time
Structured Analysis and Structured Design (RTSA/SD) and the C programming language and ASIC microcode. The
target platform was a bespoke processor comprising a number of processing subunits implemented in ASIC, some
with embedded SPARC processing capability.
The Tranche 2 Development Programme is an exercise in obsolescence management. The software is developed in
Gedae using the Tranche 1 algorithms with some elements of Tranche 1 legacy code being reused. The target platform
is a custom muliple-G4 PowerPC architecture. Future technology upgrades will require only focused changes to the
Gedae model.
In order to determine the GPF the average effort to develop the Air-to-Air radar mode at Tranche 1 was compared to
that at Tranche 2. A comparative mapping of tasks carried out during development is shown in the table below:
| Tranche 1 | Tranche 2 |
| Productivity 1 Unit | Productivity 4.5 Units |
| Real-Time Structure Analysis -RTSA | Algorithm Design Description |
| Stuctured Design | Gedae Model |
| Code | N/A/td> |
| Unit Test | Unit Test/Fagan Inspection |
| Integration Test (~16%) | Integration Test (16% by read across) |
| Acceptance Test (~16%) | Acceptance Test (16% by read across) |
The current analysis determined Captor GPF between 4.1 and 4.8. Gedae, Inc. stated that while this is an impressive improvement over in productivity over the development of the Tranche 1, the integration and acceptance phase will only serve to increase that number. Integration and acceptance are strengths of Gedae.
The mission of Gedae [‘jE dA] Inc. is to reliably deploy to military personnel the most advanced technology available, which is achieved by automating software development technology. Modern systems at times rely on implementing system complexity in software. Gedae simplifies the development complexity to ultimately enhance the quality of the software.
Gedae, Inc. delivers a software development environment for multithread applications with w with its multithread compiler and a language also known as “Gedae.” The environment surrounds these core components with a suite of supporting tools to define and implement the threads. Gedae recognizes the architecture of the target and crafts a complex application, using simple software components: highly optimized vector and interprocessor communication routines. This automation means that organizations can build their software early and explore various architectures using simulations or real hardware — never having to rewrite their software.
