Real-Time Architecture.
Abstract
The research effort this year focused in the area of developing a unified framework for reasoning about timing correctness of standards-based resources. The intent is to develop systems engineering methodologies that support the composition of standards-based distributed, real-time systems with fully predictable timing properties. Further, we worked on developing theoretic foundations to integrate real- time scheduling and fault-tolerance domains. The project members are also concerned with the transition of the theory being developed to the user community, especially the U.S. Navy. For this reason, project members have a close relationship with the RTSlA (Real-Time Scheduling in Ada) project in the CMU Software Engineering Institute. Signifcant progress has been made. The development of real-time scheduling algorithms which support time redundancy is a difficult problem. Meeting the timing requirements of a real-time application often competes with the objective of allocating redundant time to meet the deadlines of recovery operations. All too often, the problem is skirted by designing schedulers which guarantee that the timing requirements of the real-time application workload are met, ?
