AURIX TC277 Multicore Contention Model Integration for Automotive Applications

Embedded systems industry needs reliable and tight worst-case execution time (WCET) estimates for critical applications running on multicores, as a prerequisite to their adoption. While industry already uses reliable tools for single-core WCET estimation and several multicore contention models (MCMs) have been proposed, their combination have not been shown to be fully compatible with the automotive industrial practice yet. This paper reduces this gap by presenting a framework for the integration of MCMs into industrial WCET estimation practice. We illustrate such integration for a Magneti Marelli powertrain control unit on an Infineon AURIX TC277 multicore platform.
