AUTOMATED GRAPHICS AND COMPUTE TILE INTERLEAVE

摘要

A graphics system interleaves a combination of graphics renderer operations and compute shader operations. A set of API calls is analyzed to determine dependencies and identify candidates for interleaving. A compute shader is adapted to have a tiled access pattern. The interleaving is scheduled to reduce a requirement to access an external memory to perform reads and writes of intermediate data.

1. A method to reduce external memory accesses in a graphics system having an on-chip memory and an external memory, comprising:
processing a combination of tiled graphics rendering operations and tiled compute shader operations of interdependent render targets; and interleaving the combination of the tile graphics rendering operations and tiled compute shader operations automatically based on the processing.
