Subsystem-Interface Generation in the Presence of Shared Resources

Abstract
The Hierarchical Scheduling Framework (HSF) has
been introduced as a design-time framework enabling compositional
schedulability analysis of embedded software
systems with real-time properties. However, supporting resource
sharing in HSF is a major challenge, since it increases
the amount of the CPU resources required to guarantee
the schedulability of the hard real time tasks and decreases
the composability at the system level. In this paper,
we discuss and identify the key parameters of a compositional
framework called the bounded-delay resource
open environment (BROE) server to support global resource
sharing, that have a great effect on how the framework will
utilize CPU resources. Furthermore, we provide an algorithm,
that has a pseudo-polynomial complexity, to evaluate
the optimal setting for the BROE server. In addition,
we provide a polynomial-time approximation algorithm for
generating near-optimal setting for the BROE server. The
performance of the BROE server, as well as the efficiency of
the approximated algorithm, is evaluated by the means of
simulation analysis.
