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 Table 4-5 - LMB v10
• Table 4-6 and Table 4-7 - LMB BRAM IF Controller
• Table 4-8 - MicroBlaze Debug Module
