Handling Non-periodic Events Together with Complex Constrained Tasks in Distributed Real-Time Systems
Publication Type:
Conference/Workshop Paper
Venue:
16th International Conference on Control Systems and Computer Science
Abstract
In this paper we show how off-line scheduling and fixed priority
scheduling (FPS) can be combined to get the advantages of both - the
capability to cope with complex timing constraints while providing
run-time flexibility. We present a method to take advantage of the
flexibility provided by FPS while guaranteeing complex constraint
satisfaction on periodic tasks. We provide mechanisms to include FPS
servers to our previous work, to handle non-periodic events, while
still fulfilling the original complex constraints on the periodic
tasks.In some cases, e.g., when the complex constraints can not be
expressed directly by FPS, we split tasks into instances (artifacts)
to obtain a new task set with consistent FPS attributes. Our method
is optimal in the sense that it keeps the number of artifacts
minimized.
