Yes, Gack, as you put it. Now imagine a processor that's good at
character and string manipulation, table lookup scanning, buffer
manipulation, substitution, etc. and you might have something that would
do well on lots of languages, XML included. A better investment than more
general purpose processing cores? I have no clue at this point.
I should say, I've personally never been a fan of special purpose
hardware, except when either its peak or average utilization is likely to
be very high (as seems to be the case with graphics chips, ethernet chips,
and the like). It won't surprise me a bit if, even if XML processing is
offloaded, that the offload is to general purpose cores. I'm just
pointing out that the equation is changing as the relative rate of change
in clock speed vs. transistor count starts to favor the latter. There
will be increasing incentives to learn to do work in parallel as opposed
to sequentially.
Anyway, this discussion has probably gone past the point of being of
interest to a crowd that gathers here mainly to discuss XML. I'm happy to
wrap it up around now.
