Software Structure Design Techniques Applied to Embedded Computer System Software.

Constantines structured design methodology is applied to a real-time flight software program. A modified finite-state technique is successfully applied to an operational flight program OFP mainloop. Transform and transaction analysis are successfully applied to mainloop tasks. Each technique is demonstrated to show avionics software engineerscontract monitors how to get started on a design. Two hypothetical software modifications illustrate advantages of structured design over the current software implementation. Short and long term effects of structured designed OFPs are briefly described. An OFP familiarization and design methodology is developed for avionics software engineerscontract monitors.
