OpenROOM: Architecture for Real-Time Objects

The ultimate purpose of the proposed R&D is to develop and demonstrate an innovative software development environment which supports the engineering, analysis, development, test, maintenance, and reuse of software for embedded, heterogeneous, real-time systems. The proposed approach is innovative in two respects: (1) it is based on the integration of two best-of-breed environments, ObjecTime/ROOM and Java; and (2) it will provide a new technique for system performance analysis by embedding resource contention actors within executable OpenROOM models. Important technical issues to be resolved during Phase I include the compatibility of the ROOM notation and the Java language, and the avoidance of side effects from embedded resource contention actors. The overall result of Phase I research will be a demonstration of the feasibility of enhancing the ROOM design methodology to support the Java language environment. The feasibility of this environment will be shown in a limited technology demonstration involving the derivation of Java code from an OpenROOM model. The main by-products of Phase I will be set of requirements for extensions to the ObjecTime CASE tool and ROOM methodology. Requirements will also be identified for developing robust resource contention actors for common types of network devices.
