Real-time Ada software experiments

Experiments have been conducted to investigate key issues involved in developing real-time embedded Ada software and to associate experimental data and results with some often-debated features, styles, and techniques. In order to realistically estimate the impact of these Ada features, actual code from the USAF/MCAIR Ada-based integrated control system (ABICS) and integrated control and avionics for air superiority (ICAAS) programs was used in developing the experiments. The features evaluated in these experiments were chosen based on their relevance to future real-time Ada applications. The issues addressed included data typing, range constraints, compilation and link times, pragmas, parameter passing, floating point data representation, and bit manipulation. Results are presented and recommendations are made regarding several real-time Ada features and techniques relevant to future real-time, embedded Ada development
