Each transaction includes a quality of service (QoS) traffic attribute.

  • Low-latency
  • Isochronous
  • Bulk transfer

The QoS attribute is recognized by the AMBA® switches and DDR memory controller. System performance can be obtained by setting the QoS attributes appropriately. Each master can generate one or more QoS values. The traffic types are detailed in Quality of Service.
