摘要

A method, computing device, and non-transitory computer-readable medium for arbitrating data for channels in a video pipeline. The method includes determining arbitration weights for the channels. The method also includes determining which channels have arbitration weights above a threshold. The method further includes issuing data to the channels with arbitration weights above the threshold. The method also includes decrementing arbitration weights for channels for which data is issued. The method further includes repeating the determining, issuing, and decrementing until no channels have arbitration weights above the threshold.

1. A method for arbitrating data for channels in a video pipeline, the method comprising:
determining arbitration weights for the channels; determining which channels have arbitration weights above a threshold; issuing data to the channels with arbitration weights above the threshold during an arbitration cycle; decrementing arbitration weights for channels for which data is issued during the arbitration cycle using a lowest one of normalized bandwidth values assigned to the channels; and repeating the determining, issuing, and decrementing until no channels have arbitration weights above the threshold.
