With low power consumption and high performance characteristics,multi-core processors have occupied the main market.Aiming at parallel real time scheduling on multi-core platform,a scheduling algorithm combined with local and global EDF was proposed.The budgets,deadline partition,and task migration time were decided by the proposed CPU width reserved server.A memory allocation method was presented,which could manage the memory resources for parallel real time tasks effectively.Experimental results showed that the proposed new scheduling algorithm has a higher scheduling success rate.In addition,using the presented memory partition algorithm,real-time characteristics and stability of tasks were assured in memory competition situation.
