Texture Cache Refilling policy

Hi,

Just a quick question: What is the refilling policy of the texture caches (because of which we have much faster access to DRAM)?

Thanks for your time

It is undocumented. Even this very detailed paper: http://www.eecg.toronto.edu/~myrto/gpuarch-ispass2010.pdf doesn’t try to determine it. It does do a detailed analysis of the other parameters of the cache, though.
