EMI Multi-Port Arbiter
14.5 EMI Multi-Port Arbiter
The Arbiter is responsible for arbitrating requests from the ports and sending requests to
the core logic. Each transaction received at the Arbiter logic has an associated priority,
which works with each port’s arbitration logic to determine how ports issue requests to the
core logic. This memory controller supports the Bandwidth Allocation/Priority Round-Robin
arbitration scheme.
