Uhmmm like I'm speaking japanese or something today? I mean first legion now you, nobody seems to understand what I write.... ahggghhhh... Anyway, I said small pool of expensive stuff, vast pool of ultra cheap ram of less performance, akin to gamecube, but this time with useable ram instead of a-ram.
Again I don't know what tech/cost hurdles such a thing would bring, that's why I'm asking, but if none or little exist, it'd be an adequate solution for providing both high-bandwith and high amounts of ram.
IT would be costly .
THey would either have to do it cpu > fast ram > slow ram and have it go back through which i don't think they can do .
Or have
slow ram
^
cpu > fast ram
Only thing is thats two buses instead of one. THat would increase costs and complexity of the pcb .
Not only that but depending on how slow the slow ram is it may end up being the same thing as vpus having to go to main system ram . Way to slow to be usefull
