Hi everyone,

I'm trying to improve the performance of some code I have, and it
occurred to me maybe I'm not making efficient use of the cache.

However, then it occurred to me that I don't know for sure whether
the Dragonball 68k processors even *have* a cache.  I looked at
some of the documents on Motorola's (well, Freescale's) site, and
found no information either way.  I don't recall that the original
68000 chips had a cache, but I'm not sure how much of a redesign
the Dragonball chips are, so for all I know they added a cache.

While I'm asking questions, I assume the ARM processors do have a
cache.  Is that right?  Oh, and one more:  can I use floating point
in ARM code?  (I.e. are ARM-based Palms required to have floating
point ARM instructions?)
