Load Balancing for Optimal Tessellation Performance

Abstract

A system, method and a computer-readable medium for load balancing patch processing pre-tessellation are provided. The patches for drawing objects on a display screen are distributed to shader engines for parallel processing. Each shader engine generates tessellation factors for a patch, wherein a value of generated tessellation factors for the patch is unknown prior to distribution. The patches are redistributed to the shader engines pre-tessellation to load balance the shader engines for processing the patches based on the value of tessellation factors in each patch.

Dependencies are inferred from the claim text.
