Task Scheduling of Real-Time Systems on Multi-Core Embedded Processor
For multi-core embedded systems, the traditional load balancing leads to lavish power consumption by fully utilizing all cores. This paper proposes a novel load unbalancing strategy based on periodic and aperiodic tasks in hard real-time multicore embedded systems to reduce power consumption. The scheduling architecture uses a two-level scheduling scheme. At the top level, the periodic tasks are bounded to embedded cores by RBound-FF algorithm and the aperiodic tasks are dispatched to the rest cores as evenly as possible. At the bottom level, a ratemonotonic OS scheduler is adopted to schedule the periodic tasks and a deadline-monotonic OS scheduler is used to schedule the aperiodic tasks.
