A Real Time Scheduling Method for Heterogeneous Multicore Embedded Systems Oriented to Task Collaboration
Previous real-time scheduling methods for heterogeneous multi-core embedded systems resulted in excessively long system scheduling time due to setting single parameters of the real-time scheduling model.Therefore,a real-time scheduling method for hetero-geneous multi-core embedded systems oriented towards task collaboration was designed.Firstly,a real-time scheduling model for em-bedded systems is constructed for task collaboration.Then,the transmission status of system task nodes is calculated,and a mathematical model for real-time scheduling is constructed.The task data information in the constructed real-time scheduling model is collected and adaptively analyzed and processed.Based on this,the time balance control parameters and security coefficients of the real-time schedu-ling model are set to achieve real-time scheduling of embedded systems.Through the above design,the design of a real-time scheduling method for heterogeneous multi-core embedded systems is completed.In simulation experiments,compared with previous real-time scheduling methods for heterogeneous multi-core embedded systems,the designed real-time scheduling method for task collaboration o-riented heterogeneous multi-core embedded systems has a maximum scheduling time of only 5 seconds and a shorter scheduling time.
