Abstract—With the interesting of researchers to develop the scheduling of multiprocessor and distributed system in hard real time embedded systems, we present a new locking protocol called Minimizing multiple-Priority Inversion Protocol (MPIP), in this protocol, we proposed a novel mechanism to turn from preemptive to non-preemptive state to minimize multiple-priority inversion caused by low priority task on local processor. We focus on distributed locking semaphore and we showed its ability to lock the shared memory, thus; working in Multi-processor environment. We assumed all shared resources as global to avoid resource nested. With properties of our protocol, we define a new upper bound blocking time. We submit our proposal to experimental evaluation to compare it with MPCP protocol in term of hard real time schedulability.
