In this paper, we address the problem of adoptively reserving the CPU to concurrent soft real-time tasks, in order to meet target Quality of Service requirements. First, we present two new techniques inspired to the idea of stochastic control Then, we present a flexible and modular software architecture suitable for adaptive scheduling, realised as a minimally invasive set of modifications to the Linux Kernel. Finally, we show experimental results that validate our approach and prove its effectiveness in the context of multimedia applications.

Abstract
In this paper, we address the problem of adoptively reserving the CPU to concurrent soft real-time tasks, in order to meet target Quality of Service requirements. First, we present two new techniques inspired to the idea of stochastic control Then, we present a flexible and modular software architecture suitable for adaptive scheduling, realised as a minimally invasive set of modifications to the Linux Kernel. Finally, we show experimental results that validate our approach and prove its effectiveness in the context of multimedia applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
