  10. Outline Advanced Technology & Research Introduction to Volvo Group Introduction to Advanced Technology and Research Introduction to Electrical and Embedded Systems Research topics/issues within Software Systems

  11. ATR – Electrical and Embedded Systems Advanced Technology & Research Increase efficiency of software development for embedded systems Develop new AUTOSAR platform for electrical and embedded architecture supporting flexibility, energy-efficiency & functional safety Develop new dependability concepts related to architecture and knowledge transfer in the area of processes and standards Develop high efficient energy conversion focusing on electrical machines, power electronic and integrated real time control Create new embedded software development methods for multicores Develop in-vehicle wireless networks

  12. Outline Advanced Technology & Research Introduction to Volvo Group Introduction to Advanced Technology and Research Introduction to Electrical and Embedded Systems Research topics/issues within Software Systems

  13. ATR – Software Systems Advanced Technology & Research Software development processes Systems engineering Standardized software platforms and components Fault tolerant systems Multicore software systems

  14. ATR – Software Systems – Dependability Advanced Technology & Research • Functional Safety • ISO 26262, IEC 61508 • Evaluation of functional safety • Robustness evaluation • AUTOSAR platforms and software components • Fault tolerant E/E architecture • Fault tolerance mechanisms; Fault Detection, Isolation and Recovery (FDIR) • Methods and tools for fault injection, AUTOSAR-based system • Diagnostics and uptime • Reduce diagnostic time • Increase uptime

  15. ATR – Software Systems – Mixed-Critical System Advanced Technology & Research • Dimensions • Management of interferences • Safety boundaries and freedom from interferences • Compose-able verification scheme • Reduce V&V costs and efforts • Redundancy and fault tolerance • Fault/error model based on criticality level • Cost- and resource-effective mechanisms

  16. ATR – Software Systems – Multicores Advanced Technology & Research Electrical and electronic (E/E) system architectures The in-vehicle architectures can be simplified by executing the software previously run on multiple ECUs on multi-cores instead This results in a reduced number of network connections and buses, i.e. a shift towards more centralized architectures with reduced costs ECU hardware architectures A homogeneous architecture contains multiple identical cores and a heterogeneous architecture contains cores with different instruction sets The current trend is to create homogeneous multi-core devices, but significantly performance advantages can be obtained by using specialized cores and accelerators to offload the main cores

  17. ATR – Software Systems – Multicores Advanced Technology & Research Scheduling algorithms On a multi-core processor the software components must be grouped together by an algorithm and scheduled by a dispatcher task A static scheduling algorithm assigns the components to cores at build time prior to execution, this approach has been taken within the AUTOSAR consortium Worst-Case Execution Time (WCET) analysis Used to find upper bounds for the largest possible execution time of software Important when verifying the timing properties of safety-critical real-time systems By introducing multi-core processors the analysis previously done on single-core processors cannot be used out-of-the box, hence new analysis methods needed
