A Real Time Scheduling Method for Embedded Multimedia Applications
For applications of embedded systems, several processors are scheduled on a processor because very limited applications are used. Recently application areas are broadened and used to be like personal computers. Operating systems are considered one of critical factors to develop embedded systems. Linux is becoming one of popular operating systems for embedded applications, because of open source...
متن کاملReal-Time Scheduling for Multimedia Services
High-speed networks and high-performance workstations are necessary but not sufficient to support distributed multimedia applications. A real-time scheduling system designed for multimedia data types is also required to orchestrate communications channels, disk storage units, output devices, and the CPU. These subsystems are coordinated to accommodate the special requirements of multimedia data...
متن کاملPeriod detection for legacy real-time applications for improving the efficiency in resource scheduling
In this paper, the problem is addressed of online identification of the optimum scheduling parameters for providing QoS guarantees to multimedia applications. In the proposed approach, the application is required to be modified for using any specific API, but rather its timing behaviour is automatically identified, and appropriate scheduling guarantees are provided by the OS seamlessly, making ...
متن کاملUDP Lite for Real Time Multimedia Applications
We introduce UDP Lite – a lightweight version of UDP with increased flexibility in the form of a partial checksum. It allows senders to specify packets as partially insensitive to errors. The coverage of the checksum is specified by the sending application on a per-packet basis. Because of its close relationship to UDP, UDP Lite is easily integrated into an existing UDP implementation. UDP is a...
متن کاملAdaptive Scheduling for Real-time Network Communication
Distributed real-time applications require efficient scheduling to improve processor and network utilization, and to avoid missing task deadlines. Current scheduling algorithms typically do not utilize applicationlevel information nor do they adapt to changes in application state. We describe a system in which users define dynamic, application-specific, scheduling policies using a fuzzy-logic a...
