Title
Utilisation Bounds Of P-Frp Tasks
Abstract
Priority-based functional reactive programming (P-FRP) is a new functional programming formalism for developing safety-critical embedded systems. P-FRP allows static priority assignment and guarantees real-time response by preempting lower priority tasks. Due to the state-less nature of functional programmes, preempted tasks in P-FRP are aborted and have to restart after the higher priority tasks have completed execution. Since the execution semantics of P-FRP are different from the classical preemptive model of execution, existing utilisation-based sufficient conditions cannot be applied. In this paper, we derive a new utilisation-based sufficient schedulability condition for P-FRP, and validate it using experimental task sets. We then compare the sufficient schedulability condition of P-FRP with that of the preemptive model to demonstrate the severe restrictions on task set sizes in P-FRP. Effect on the utilisation bound under conditional preemption has also been analysed.
