8.4 Application of Microprocessors
A variety of microprocessors come into use in the 5017.
In order to support a certain level of modularity in the individual systems, it is desir-
able to make the modules as autonomous as possible.
This is achieved through diverse microprocessors of varying capacities. Each mod-
ule, equipped with its own processor, is therefore tested independently of other mod-
ules, through its own set of test routines.

This allows the error rate to be kept as small as possible, since each module has its
own, independent test programs, which can operate independently from other mod-
ules, guaranteeing optimal functional security.
Another consequence of such a level of modularity is that updates are easy to carry
out, and it is easier to make modifications that suit specific customer needs.
Main Processor
The main processor is a powerful 32-Bit CPU, which takes over the coordination of
the various modules, as well as communication between them and supervision over
them.
