Cyclic dependencies in modular performance analysis
Bengt Jönsson, Simon Perathoner, Lothar Thiele, Wang Yi · 2008
The Modular Performance Analysis based on Real-Time Calculus (MPA-RTC), developed by Thiele et al., is an abstraction for the analysis of component-based real-time systems. The formalism uses an abstract stream model to characterize both workload and availability of computation and communication resources. Components can then be viewed as stream transformers. The Real-Time Calculus has been used successfully on systems where dependencies between components, via either workload or resource streams, are acyclic. For systems with cyclic dependencies the foundations and performance of the formalism are less well understood.
