Abstract:
Display pipeline may manage allocation of total memory bandwidth to memory access requester blocks (e.g., display pipeline as a whole and/or a block in the display pipeline) by dynamically allocating the total memory bandwidth based at least in part on a calculated bandwidth floor to reduce the communication inefficiency (e.g., underruns), excessive power consumption, and image quality degradation of the display pipeline. Image fetch parameters, electronic display parameters, display pipeline parameters, and memory access requester block parameters may be used to determine the appropriate bandwidth floor for each memory access requester of the display pipeline. Additional memory bandwidth may be allocated to memory access requesters of the display pipeline when available bandwidth remains to further reduce likelihood of subsequent communication inefficiencies in the display pipeline.
