The introduction of component-based development into real-time embedded platforms is desirable to adapt themselves to the heterogeneity of embedded applications, and it is necessary to satisfy the requirement of software development efficiency. Due to the dynamic resource requesting of real-time embedded platforms and the overall administrative features of system resources, the adaptation mechanism in application level is not the final solution, furthermore the additional QoS managing policy plugged into the current component framework is requisite. Thus, a CCM component-oriented QoS model was...
