Abstract

Resource efficient approaches is of great importance for resource constraint embedded systems. A recent resource efficient solution, which is based on a server-based bandwidth reservation technique, combines the traditional partitioned and global scheduling approaches to achieve low migration overhead and high utilization. In this multiprocessor layout some target tasks are scheduled using partitioned scheduling while a known processor bandwidth per core is reserved to schedule a dedicated set of tasks globally. However, this scheduling approach assumes that tasks are independent and do not share resources other than the CPU. This paper proposes the first suspension-based real- time synchronization protocol for the hybrid partitioned/global scheduling structure. The paper addresses the challenges arisen from a locking point of view where a core is affected by both partitioned and globally scheduled tasks.
