8.2.9.1.2. Arbitration and Quality of Service in the SDRAM Scheduler

The SDRAM scheduler controls arbitration priorities internally for optimal end-to-end quality of service. You can apply QoS settings to each port of the SDRAM scheduler to control the bandwidth available to each master.

Each master on the SDRAM scheduler has software-programmable QoS signals. These signals are propagated to the scheduler and used as arbitration criteria for access to SDRAM.

For information about programming quality of service for the FPGA-to-SDRAM masters, refer to "Functional Description of the QoS Generators" and "Configuring the Quality of Service Logic".
