Abstract :
A priority-based synchronization protocol that explicitly uses shared-memory primitives is defined and analyzed. A solution that has been proposed for bounding and minimizing synchronization delays in real-time systems is briefly reviewed. The waiting times introduced by synchronization requirements in multiple-processor environments are identified, and a set of goals for priority-based multiprocessor synchronization protocols is derived. The underlying priority consideration for a shared memory synchronization protocol are studied and priority assignments to be used by the protocol are derived
