Compensating for Interrupt Process Times in Real-Time Multimedia Systems
This paper describes an on-going work focused on using Adaptive Reservations to cope with unpredictabilities due to the interrupt processing times in real-time kernels. Using this approach, the execution time stolen by interrupt processing is modeled as a variation in the application execution times, and an adaptive scheduling mechanism automatically compensates its effects.
متن کاملSupporting the Hard Real-Time Requirements of Mechatronic Systems by 2-Level Interrupt Service Management
Mechatronic systems often require hard real-time behaviour of the controlling system. The standard solution for this kind of application is based on the timetriggered approach, and for certain circumstances the schedulability is provable. In contrast to this, the approach in this paper introduces some hardware enhancements that allow first to substitute the timetriggered system by an event-trig...
متن کاملTransparent and Selective Real-Time Interrupt Services for Performance Improvement
The popularity of mobile and multimedia applications made real-time support a mandatory feature for embedded operating systems. However, the current situation is that the overall performance is significantly degraded due to the real-time support. This paper suggests a novel scheme to minimize the performance degradation in embedded operating systems with real-time support. Especially, we propos...
متن کاملIntegrated Intra- and Inter-task Cache Analysis for Preemptive Multi-tasking Real-Time Systems
In this paper, we propose a timing analysis approach for preemptive multi-tasking real-time systems with caches. The approach focuses on the cache reload overhead caused by preemptions. The Worst Case Response Time (WCRT) of each task is estimated by incorporating cache reload overhead. After acquiring the WCRT of each task, we can further analyze the schedulability of the system. Four sets of ...
متن کاملAccounting for interrupt handling costs in dynamic priority task systems
In order to apply the results of formal studies of real-time task models, a practitioner must account for the effects of phenomena present in the implementation but not present in the formal model. We study the feasibility and schedulability problems for periodic tasks that must compete for the processor with interrupt handlers –– tasks that are assumed to always have priority over application ...
