Abstract : This workshop, held May 10-11, 1990 at the University of Virginia, was the seventh in a continuing series of workshops on real-time operating systems and software. This workshop, co-sponsored by the IEEE Computer Society Technical Committee on Real-Time Systems and the Office of Naval Research, had as its goals: to investigate advances in real-time operating systems; to promote interaction among researchers and practitioners; and to evaluate the maturity and evolutionary directions of real-time programming theories and approaches. This report contains the Proceedings of the Conference as well as a Final Report to IEEE and additional budgetary information provided to the Office of Naval Research. Keywords: Data bases, Concurrency, Computer architecture.
