TC
Texture Cache
TCC
Texture Cache per Channel - L2 cache attached to the memory channels.
May be used when shader cores are accessing memory.
Despite "Texture" in the name, this is used by any kind of memory access.
TCCs may be mapped to TCPs, depending on the architecture.
TCP (AMDGPU)
Texture Cache per Pipe. Even though the name "Texture" is part of this
Texture Cache per Pipe - L1 cache attached to each CU.
Even though the name "Texture" is part of this
acronym, the TCP represents the path to memory shaders; i.e., it is not
related to texture. The name is a leftover from older designs where shader
stages had different cache designs; it refers to the L1 cache in older
