Abstract
A method of exchanging data in a real-time operating system, between a primary core and a secondary core in a multi-core processor, includes executing a primary path via the primary core and executing a secondary path via the secondary core. The primary path is configured to be a relatively faster processing task and the secondary path is configured to be a relatively slower processing task. The method includes devising a freeze in process flag to have a respective flag status set and cleared by the primary path. The method includes devising a data frozen flag to have a respective flag status set and cleared by both the primary and the secondary paths. A component that is operatively connected to the multi-core processor may be controlled based at least partially on a difference between primary and secondary sets of calculations executed by the primary and secondary cores, respectively.
