ADAPTIVE MULTILEVEL BINNING TO IMPROVE HIERARCHICAL CACHING

摘要

A device driver calculates a tile size for a plurality of cache memories in a cache hierarchy. The device driver calculates a storage capacity of a first cache memory. The device driver calculates a first tile size based on the storage capacity of the first cache memory and one or more additional characteristics. The device driver calculates a storage capacity of a second cache memory. The device driver calculates a second tile size based on the storage capacity of the second cache memory and one or more additional characteristics, where the second tile size is different than the first tile size. The device driver transmits the second tile size to a second coalescing binning unit. One advantage of the disclosed techniques is that data locality and cache memory hit rates are improved where tile size is optimized for each cache level in the cache hierarchy.

1. A method for calculating a tile size for a plurality of cache memories in a cache hierarchy, the method comprising:
calculating a storage capacity of a first cache memory; calculating a first tile size based on the storage capacity of the first cache memory and one or more characteristics of data being processed in a first portion of a graphics processing pipeline; transmitting the first tile size to a first coalescing binning unit; calculating a storage capacity of a second cache memory; calculating a second tile size based on the storage capacity of the second cache memory and one or more characteristics of data being processed in a second portion of the graphics processing pipeline, wherein the second tile size is different than the first tile size; transmitting the second tile size to a second coalescing binning unit.
