ABSTRACT
<p>Formal results for precedence constrained, real-time scheduling of unit time tasks are extended to arbitrary timed tasks with preemption. An exact characterisation of the EDF-like schedulers that can be used to transparently enforce precedence constraints among tasks is shown. These extended results are then integrated with a well-known protocol that handles real-time scheduling of tasks with shared resources, but does not consider precedence constraints. This results in schedulability formulas for task sets which allow preemption, shared resources, and precedence constraints, and a practical algorithm for many real-time uniprocessor systems.</p>
