A footnote to my previous msg:
Andy Glew later told me that his bosses at Intel were pretty certain
he'd leaked the EMON info to me, they didn't believe it was possible to
reverse engineer them the way I described in my article.
It seemed like they changed their minds half a year later, after the
FDIV incident, but that's another story. :-)

checking...
It seems like I don't have any copies myself. :-(
I know there used to be one on the byte.com web site, but that's years
ago...
Yes, it is still there!

Thanks Terje, I really should have looked there but I thought that Byte
had folded some time ago.
I am sorry to keep aking you questions, but do you know of any good
documents on the web that explain how caches work, especially in the x86
family? I ask because it is hard going through the Intel/AMD
documentation and I am hence rather hoping that someone has produced a
good tutorial style document on all of this.

_Good_ tutorials are always worthwhile.

Dunno about the web and dunno about modern x86's, but Michael Schmitt's
book "Pentium Processor Optimization Techniques" was very informative
about the Pentium 1. |

You could try "The Anatomy of a High-Performance Microprocessor" by Shriver
and Smith. It's on the web via one level of indirection.
