Implementation of the Virtual Address Space Mapping in Embeded Linux Kernel

Aiming at the need of the porting of embedded linux kernel,an implementation scheme of the virtual address space mapping in the embedded linux kernel is present.The fundamental principle of the virtual address space mapping was introduced both from the software and hardware point views.This paper also states the practical implementation of the virtual address mapping on the 805 plus platform.The result of the experiment shows that the platform can perform the addressing and system initialization correctly when the MMU is turn on.
