ATR – Software Systems – Multicores

2012-10-16

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

2012-10-16

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
