An Integrated Framework for Model-Based Design and Analysis of Automotive Multi-Core Systems

Abstract : With technological advances, significant changes occur in automotive domain. Modern automobile combines various functionalities, ranging from safety critical functions, e.g. control systems for engine and break, to navigation and infotainment. The latter ones are especially performance-demanding. To meet their requirements, automotive industry is increasingly turning to multi-core systems. As a result, the design complexity gets increased. This paper presents a design exploration framework relying on an automotive-specific design environment named Amalthea. Applications are modeled in Amalthea as annotated hierarchical task graphs. Their simulation on multi-core platforms considers instruction-level core models interconnected by a packet-based communication network. The effectiveness of our framework is demonstrated on a representative case study.
