Abstract
In this paper we present a framework for dynamically al­
locating the CPU resource to tasks whose execution times
are not known a priori. Tasks are partitioned in three
classes: the ones that require a uniform execution but do not
impose any temporal constraint, periodic tasks that operate
on Continuous Media, and event driven tasks that respond
to external interrupts. For the last two classes, we show
how to adjust the fraction of the CPU bandwidth assigned
to each task using a feedback mechanism.
