Abstract
A method is provided for detecting a race condition of a parallel task when accessing a shared resource in a multi-core processing system. The method requires that a core requires only a read access to the data set of another core, thereby ensuring better decoupling of the tasks. In an initialisation phase, initial values of global variables are assigned, in an activation phase, each core determines if the other core has written new values to the variables and if so, detects a race condition. Initial values are restored for each variable in a deactivation phase.
