Abstract
In an embodiment a method for managing access rights of software tasks executed by a processing unit (CPU) using a cache memory containing execution data of the tasks in memory locations, each execution data having an attribute representative of a level of access right of the respective task, includes changing the attributes of the locations of the cache memory when the access rights of at least one task changes and retaining the execution data contained in the locations of the cache memory.
