A new approach for global synchronization in hierarchical scheduled real-time systems

We present our ongoing work to improve an existing synchronization protocol SIRAP for hierarchically scheduled real-time systems. A less pessimistic schedulability analysis is presented which can make the SIRAP protocol more efficient in terms of calculated CPU resource needs. In addition and for the same reason, an extended version of SIRAP is proposed, which decreases the interference from lower priority tasks. The new version of SIRAP has the potential to make the protocol more resource efficient than the original one.
