The MESIF protocol is a cache coherency and memory coherence protocol developed by Intel for cache coherent non-uniform memory architectures. The protocol consists of five states, Modified (M), Exclusive (E), Shared (S), Invalid (I) and Forward (F). The M, E, S and I states are the same as in the MESI protocol. The F … See more The F state in this protocol should not be confused with the "Owner" O state in the MOESI protocol.

WebThere are two ways a GPU could be connected with hardware coherency: IO coherency (also known as one-way coherency) using ACE-Lite where the GPU can read from CPU caches. Examples include the ARM Mali™-T600, 700 and 800 series GPUs. Full coherency using full ACE, where CPU and GPU can see each other’s caches. http://fidepost.com/discerner-le-prelat-de-lintrus-orthodoxie-et-perpetuite-de-la-bulle-cum-ex-apostolatus-officio-du-bienheureux-paul-iv-par-labbe-henri-mouraux/
