So i can think of TrustZone as separate OS rite? ..Whenever normal OS wants a secure action to be taken , it reboots or calls the other secure OS and does the action securely. So TrustZone is like an extra OS in which one can perform safely all sensitive operations !
This website that GopuSierra posted says" To improve security, these ARM processors can run a secure operating system (secure OS) and a normal operating system (normal OS) at the same time from a single core "...But people here in forum say both OS do not run concurrently..Who is right? PLEASE DO NOT CONFUSE ME MORE ..
anyone can please explain what is 'virtualisation'
what does ARM mean by saying they provide a hardware enforced virtualisation ?
