This is a re-submission, because I am not getting any response from superuser.com. Sorry for the misunderstanding.
I need to know the difference between physical addressing and virtual addressing concept in embedded systems.
Why virtual addressing concept is implemented in embedded systems?
What is the advantage of the virtual addressing over a system with physical addressing concept in embedded systems?
How the mapping between virtual addressing to physical addressing is done in embedded systems?
Please, explain the above concept with some simple examples in some simple architecture.
