Abstract:
In an embodiment, a display control unit is configured to transmit read operations to the memory in the system to read image data for processing, and may employ QoS levels with the read operations to ensure that enough data is provided to satisfy the real time display requirements. To determine which QoS level to use for a given read request, the display control unit may be configured to compare an amount of image data in the display control unit (e.g. in various input and/or output buffers in the display control unit) to one or more thresholds. The display control unit may also be configured to dynamically update the thresholds based on a memory stress level in the memory controller.
