Arbitration: Why is HADDR sometimes shown as an input to the arbiter?

Applies to: AHB


The address bus, HADDR, is not required as an input to the arbiter but in some system designs it may be useful to use the address bus to determine a good point to change over between bus masters. For example, the arbiter could be designed to change bus ownership when a burst of transfers reaches a quad word boundary.
