Data Orientated Requirements Implementation Scheme (DORIS)

The Data Orientated Requirements Implementation Scheme (DORIS) is a set of integrated methods for the development of real time, embedded, multi-processor systems. It covers the whole of the development life cycle from requirements elicitation and system definition, through design, and on into implementation in software and digital hardware. It has been specially formulated to promote the highest levels of integrity in digital and software system development. The unifying theme which runs through all aspects of DORIS is dataflow, and it draws on existing data flow methods where possible and appropriate. The principal component methods are: CORE, MASCOT, and DIA. The author outlines the principal architectural concepts and indicates some of the effects on Mascot design
