A Modeling Methodology for Real-Timemultimedia Operating Systems

Real-time scheduling theory attempts to guarantee that a
real-time task set will always meet its deadlines. Historically,
there has existed a wide gap between real-time scheduling
theory and the reality of applying the theory to task sets
implemented via real-time operating systems (RTOSs). This
paper provides aftamwork to account for implementation
costs in real-time scheduling theory. In addition, an
engineering methodology that allows users and developers
to accurately model and evaluate RTOSs is presented. We
use this methodology to model three dinerent commercial
real-time operating systems that are being used in
multimedia applications. We show how to use the RTOS
scheduling models to evaluate the performance and design
of RTOSs. Subscribe to Complete IEEE Topics and Abstract by Email For more IEEE Topics .
