Lines Matching defs:as
13 Tiling (sometimes referred to as swizzling) is a method of re-arranging the

112 width, as the stencil buffer is stored with two rows interleaved.

172 X-tiling and performs much better in practice. Each Y-tile is an 8x8 grid of cache lines arranged Y-major as follows:
186 Each 64B cache line within the tile is laid out as 4 rows of 16B each:
196 Y-tiling is widely regarded as being substantially faster than X-tiling so it
215 buffers. W-tiling is similar to Y-tiling in that it's arranged as an 8x8
216 Y-major grid of cache lines. The bytes within each cache line are arranged as
232 the docs are somewhat confused as to whether stencil buffers are W or Y-tiled.
