Abstract(s)
Composition is a practice of key importance in software engineering. When real-time applications are composed it is
necessary that their timing properties (such as meeting the deadlines) are guaranteed. The composition is performed by
establishing an interface between the application and the physical platform. Such an interface does typically contain
information about the amount of computing capacity needed by the application. In multiprocessor platforms, the
interface should also present information about the degree of parallelism. Recently there have been quite a few interface
proposals. However, they are either too complex to be handled or too pessimistic.In this paper we propose the
Generalized Multiprocessor Periodic Resource model (GMPR) that is strictly superior to the MPR model without
requiring a too detailed description. We describe a method to generate the interface from the application specification.
All these methods have been implemented in Matlab routines that are publicly available.
