This paper describes a modeling project which was established to support the design of a distributed controller system. An anthropomorphic robot hand is the target system. Stochastic Petri net models for different communication schemes were developed in order to predict the performance of the considered systems. For a given workload a bus communication can not be used, but two alternative ring structures are able to meet the predefined timing requirements. Design and performance evaluation of the models were realized using the new Petri net tool TimeNET, which allows the modeling with non-Markovian Petri nets and combines a graphical user interface with powerful solution and simulation methods.<>

Mapping, i.e., allocating resources to applications and finding I/O routes between resources, is a crucial step in meeting real-time/multi-media applications' end-to-end timing requirements. Given a set of real-time applications, the order in which they are mapped can also greatly impact whether these timing requirements are met. Because the optimal ordering solution is intractable, this paper introduces a logical application stream laxity metric that can be used to order the application streams in linear time that produces excellent results. We apply this metric to an example audio/video application set to illustrate our approach and to compare our solution to the optimal one.<>

TIBBIT is a method of performing a binary to binary translation of an application from one architecture (source) to another (target) while maintaining the timing behavior of the code, even when it depends upon the speed (e.g. clock rate) of the host processor. Translated applications are scheduled under a real-time operating system on the target system such that processor-speed dependent behavior is accounted for and held equivalent. This work extends the technique from the single-processor implementation to include translation from single- and multiprocessor sources to multiprocessor targets.<>
