I don't recall what the P stands for, but it might be worth calling out that the texture cache (old name) is basically the path to memory for shaders. So it's not just related to textures. The name is left over from old designs where shader stages had different cache designs. > + > TOC > Table of Contents > > UMSCH > User Mode Scheduler > > + UTCL > + Universal Texture Cache Line I think the L is Level. I.e., it's usually referenced as UTCL2 for example. Might want to drop the L? I think the U might also be Unified. Alex > + > UVD > Unified Video Decoder > > -- > 2.51.0 >
