Abstract : The purpose of the project was to produce a flexible and simple executive structure, supporting a broad spectrum of approaches to scheduling, parallel processing, resource allocation and graceful degradation. The executive itself must be capable of operating dedicated to a single processor, to float freely among processors, or any combination of the two methods. The executive must have wide applicability among many types of multiprocessor devices and real-time data processing applications. The executive structure is to be used in future ground-based, airborne and spaceborne applications by tailoring the design to given specific mission computing requirements. This approach is expected to avoid the conventional difficulties of software production by facilitating timely and orderly planning and implementation of software for aerospace multiprocessors.
