Integrating independently developed real-time applications on a shared multi-core architecture

Abstract

The shift towards multi-core platforms has become inevitable from an industry perspective, therefore proper techniques are needed to deal with challenges related to this migration from single core architectures to a multi-core architecture. One of the main concerns for system developers in this context is the migration of legacy real-time systems to multi-core architectures. To address this concern and to simplify the migration, independently-developed subsystems are abstracted with an interface, such that when working with multiple independently-developed subsystems to be integrated on a shared platform, one does not need to be aware of information or policies used in other subsystems in order to determine subsystem-level schedulability. Instead schedulability can be checked through their interfaces at the time of integration on a shared multi-core architecture. In this paper we propose a solution for investigating the system schedulability via providing interfaces for independently-developed subsystems where some of them are distributed over more than one processor and may share resources.
