METHOD FOR PORTING A SINGLE-CORE CONTROL SOFTWARE TO A MULTI-CORE CONTROL DEVICE OR FOR OPTIMIZING A MULTI-CORE CONTROL SOFTWARE

摘要

A method for porting an existing vehicle control software developed for a single-core control device into a modified multi-core control software or for converting an existing vehicle control software into an optimized multi-core control software is provided. The existing control software comprises numerous repeatedly executable runnables. Information is exchanged between the runnables through writing and reading of communication variables. A modified information exchange via time implicit communication is provided for parallelized runnables in the multi-core control software that is generated by the method. The method includes: analysis of the existing control software regarding a writer-to-reader cardinality of the information exchange with respect to a communication variable; and defining an implementation of the time implicit communication as a function of the determined writer-to-reader cardinality.
