Parameter Values
To create a MicroBlaze MCS that is uniquely tailored for a specific system, certain features
can be parameterized. This makes it possible for the user to configure a component that
only uses the resources required by the system, and operates with the best possible
performance. The features that can be parameterized in MicroBlaze MCS are shown in
Table
4-1.
The internal modules of the MicroBlaze MCS have fixed configurations detailed in:
•
Table 4-2
- MicroBlaze
•
Table 4-3
- I/O Module
•
Table 4-4
and
•
