Compensating for Interrupt Process Times in Real-Time Multimedia Systems
暂无分享,去创建一个
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.
