abstract

  • This paper presents a software framework containing a reconfiguration mechanism that provides realtime execution guarantees in intensive media processing consumer electronic devices. Our approach offers real-time guarantees during all of the system operation, i.e., not only during the normal media processing mode but also in the event of reconfigurations (a reconfiguration is a transition among two different system states). This approach enhances the budget scheduling model to provide a time-partition that guarantees the availability of resources during transitions. Results are presented that validate the proposed approach.
