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

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
