Claim Text:
1. A method comprising: identifying an oldest output pixel stored in a display pipeline for a first requestor; identifying an oldest outstanding pixel fetch request of the first requestor, wherein the oldest outstanding pixel fetch request is for a first source pixel; calculating an output equivalent coordinate of the first source pixel, wherein the output equivalent coordinate of the first source pixel is a coordinate of an earliest output pixel that cannot be generated without the first source pixel; calculating a first distance in output pixels between the oldest output pixel and the output equivalent coordinate of the first source pixel within a given output frame; determining a first quality of service (QoS) level based at least in part on the first distance; and assigning the first QoS level to the oldest outstanding pixel fetch request of the first requestor, wherein requests with the first QoS level are serviced with a higher priority than requests with a second QoS level.
