Disks are largely useless in realtime signal processing, because you need some ~10 ms for an acess. Solid-state drives are better, and I genuinely hope we'd be getting nonvolatile (MRAM or other spintronics) storage for main memory which would make rotating magnetic bits (or worse -- tape) obsolete. But then, we've been waiting for these since bubble memories. One could argue vaguely about some rare lookup access on a very large assembly (terabytes or petabytes) which fetches some hard-to-compute information, but I have not seen any plausible AI architecture where this has been demonstrated empirically to work. Arguably even RAM are useless for realtime, since you need ~second to stream through a node's memory. And that's just one iteration. And it's not random-access, so it can get some 10-20 times as slow. Now if you could process the entire ~GByte chunk in ~1 us.. 100 ns steps, that'd be interesting. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
