Intel Hands Atom RTL to RosaicLabs for Custom x86 Matrix Engine

RosaicLabs, Atom RTL, and 32-Tile AMX: Trying to Piece Together a x86 Puzzle

I am investigating a surprising deal where Intel provides Atom CPU register transfer language code to a new startup called RosaicLabs. This move, combined with reports of a mysterious x86 implementation featuring 32 Advanced Matrix Extension tiles, suggests a new strategy for building specialized AI accelerators. RosaicLabs, led by Rivos veterans, appears to be leveraging this access to create a unique processor that pairs an efficient x86 core with a massive matrix engine.
