Mixed-criticality Hierarchical Scheduling for TI-RTOS
Hesham Hussien, Eman Shaaban, Said Ghonaimy · 2018
the paper proposes an enhanced adaptive hierarchical scheduling framework for mixed criticality systems, based on EDF with Virtual Deadline. It provides temporal partitioning between concurrent independent applications with periodically and dynamically assigning CPU budget for each application. It is implemented into kernel of TI-RTOS on a limited resource platform. Results show that it enhances the performance of our previously proposed AHSF-EDF during overload conditions, and ensures that critical tasks assigned to a server meet their deadlines at the expense of other less critical tasks assigned to the same server.
