8.2.11.2. QoS Mechanisms

The QoS generators influence arbitration priorities by manipulating urgency, pressure, and hurry.

When two or more packets compete for an interconnect resource at an arbitration node, the arbitration logic selects the packet with the highest priority. QoS generators can control the behavior of the arbitration logic by modifying the priority of packets through urgency, pressure, and hurry.

The QoS controls for each master are separated into read and write QoS controls.
