7.1. Adding bus masters

For bus masters, the arbiter is the only block that requires changes.

The arbiter currently has facilities for up to two more masters without any modification. A new master needs to be connected to the appropriate HBUSREQx and HGRANTx signals. This can be done by altering the top-level HDL file, which connects all AHB modules together.


If a system requires more than four masters, the arbiter HDL file also has to be modified.
