[[AN-BELK-001:_Asymmetric_Multiprocessing_(AMP)_on_Bora_–_Linux_FreeRTOS|Traditional AMP]]<ref name="AN-BELK-001"></ref> configuration satisfies [[#REQ1|REQ1]] through [[#REQ4|REQ4]]. [[#REQ5|REQ5]] through [[#REQ8|REQ8]] are not satisfied instead. About integrity, for example, an application with ''root'' privileges could access memory regions that are supposed to be exclusively accessed by code executed in W1. This may lead to unpredictable behaviors and to potentially catastrophic consequences. This is where TrustZone technology comes to help: it establishes a sort of barrier between the two worlds and prevents W2 code from unauthorized accesses to certain regions of the processor's addressing space.
