Towards Probabilistic Mode Automata for Adaptable Resource-Aware Component-Based Systems Design

Conference/Workshop Paper


Improving Systems and Software Engineering Conference / Software Engineering Process Groups Conference


Embedded systems design, configuration, deployment and runtime management are extremely challenging. The pervasiveness of embedded systems, and their increasing parallelism and scale in number of networked and interacting hardware-software components, has been coupled with increases in the number of functions and the variation in behaviour and characteristics of these functions. Adoption of new international safety standards and higher best practice levels in large manufacturer subcontracting policies however mandates strict quality and at times even stricter dependability and sustainability (in particular energy efficiency) requirements. In recent work we have extended our rich architecture definition language (RADL) and underlying theory to meet such industrial requirements. In this paper we describe a new approach and design model targeting hybrid designer- and operator defined performance budgets for timing and energy consumption. We give a running example designing a sample embedded multi-media system, a modern digital camera. The model caters for true parallelism, probabilistic performance characterisation, parameterised architectural variation, compositionality, and runtime reconfiguration. The theory is based on hybrid, hierarchical, performance-annotated parallel automata and Petri nets. We also briefly summarise our tool set used to derive the example.
