The enhanced Memory Management and Protection Unit allows a secure separation of the operating system
and different applications. It allows to separate the memories in application orientated segments, which can
be controlled by the OS. Furthermore, the MMU makes a secure downloading of applications possible even
after personalization of a card. These new features suit the requirements of the next generation of
multi-application operating systems.

The new platform is designed to address up to 16 Mbyte. However this feature is only available upon request
and will clearly require a change in the existing tool environment.
In addition, new instructions have been implemented in the design for an efficient direct access of physical
memory >64Kbyte up to 16 Mbyte.
