drkohler said: It means the gpu can have cache coherent access to the cpu memory. Notice there is no coherency between esram and cpu, though. Unfortunately there is this small, bidirectional, black arrow between cpu and esram. Nobody has yet figured out what this arrow means. As long as ms doesn't explain what that arrow is, all bets are off about full huma (ms's way of doing it) or not. |
To start to think in hUMA we need to know if the CPU have coherent access to the GPU-cache... the diagram is clear about GPU having access to CPU-cache but what about the reverse?
After that we need to see how this eSRAM works... that black link is intersting but means nothing without more details :(
