Abstract

Embodiments of computer processing systems and methods are provided that include a memory protection unit (MPU) (60), and a plurality of region descriptors 62 associated with the MPU. The region descriptors include address range and translation identifier values for a respective region of memory. Control logic determines whether a translation identifier control indicator is in a first state, and if the translation identifier control indicator is in the first state, the control logic allows a first process being executed by the processing system to access a memory region allocated to a second process being executed by the processing system.
