Supporting Component-Based Development in Partitioned Multiprocessor Real-Time Systems

The fast evolution of multicore systems, combined with the need of sharing the same platform for independently developed software, demands for new methodologies and algorithms that allow resource partitioning, while guaranteeing the isolation of concurrent applications. Unfortunately, a major problem that can break the isolation property of concurrent partitions is resource sharing. Although a number of resource access protocols exist for hierarchical uniprocessor systems, no protocols are available today for managing hierarchical partitions implemented on top a multiporcessor platform under partitioned scheduling. This paper presents a framework to support component based design on a multiprocessor platform and proposes a novel reservation server mechanism, called M-BROE, to handle shared resources in multiprocessor systems in the presence of resource reservation scheduling mechanisms.
