Abstract
Described herein are computer graphics technologies to facilitate effective and efficient memory handling for blocks of memory including texture maps. More particularly, one or more implementations described herein facilitates hierarchical lossless compression of memory with null data support for memory resources, including texture maps. More particularly still, one or more implementations described herein facilitates the use of meta-data for lossless compression and the support of null encodings for Tiled Resources. This technology also permits use of the fast-clear compression method, where meta-data specifies that the entire access should return some specified clear value.
