Can you really do an enormous SRAM on a bigger node without it occupying a huge surface? Would 14nm be cheap enough for that to be interesting? If so, why not also use it for other big structures?

Maybe while resuming from interrupt you go slow for a while, although I suspect you eventually recover even if that happen. The interrupt will be slow as hell anyway, regardless of if you are doing rep movsb or not. Actually rep movsb with

rep movsb has been quite optimized recently and I suspect it will continue to be. Today you can be faster with more complex solutions in some cases, and depending on your precise microarch alternate solution for small copies, etc., but I su

Overlong encoding is not just non-canonical UTF-8. It is actually forbidden; it is not UTF-8. A decoder without checks can as well not return the codepoints you expect at all (that would be curious but if you try to heavily optimize one, ma

More like the moment you add a second Mutex in your app, ad-hoc handling and no policy to prevent deadlocks. The solutions are well known and I'm simply sad to see them far too little used. But in the case you insist in doing that (n

If you need deadlock detection, probably your high level design is problematic. But I agree this is extremely often the case, so that's extremely often an interesting and valuable tool.

So just because some internal symbols have been leaked (or even have been published by MS in symbols tables) you can copy them legally ? But somehow you can't copy the source code ? But however you can copy a hand (or tool assisted) di

That's very true but I also think of one important aspect: the parts of the research space we choose to look in. And like a novel is not discovered in the absurdly large research space of sequences of random characters, nor even disc

The chips are huge and numerous & you would have to boostrap a market to compete, that's hard. Technically it can be "duplicated", but in the same sense that Apple can make a state of the art processor better than Intel:

This can be used to justify any kind of crap being shipped in newly introduced features, merely baring regressions. Therefore I don't value the approach as presented here. But a sane variant could be interesting: anyway I suspect it wi

Well you have the multiprocessor memory model for example. Technically, you could use a stricter one (from x86) on arm, but that would maybe prevent some non-atomic efficiency gains, and if it's for a platform with competitor chips t
