Task scheduling with RT constraints
Marco Di Natale, Alberto Luigi Sangiovanni-Vincentelli, Felice Balarin · 2000
This paper addresses the problem of schedu ling reactive real-time tran saction s(task groups) implementing a net work of extend ed Finite State Machines comm unicating asynchronously. Task instances are activated in response to internal and/or external ev ents.The objective is avoiding the loss of events exchanged by the tasks. This sc heduling problem has many similarities with the conventional formulation of real-tim e problems and yet it differs enough to justify a rethinking of the assu mptions an d techniques used to solve the problem. Our iterative solution targets fixed p riority systems and offers a priority assignment scheme together with a sufficiently tight worst-case analysis.
