hi,
sorry to ask this here but i'm finding difficulty getting this info
elsewhere...
I'm not an assembly programmer and i know little about cpu's. it's a hole in
my knowledge i guess. i'm looking for some technical introduction doc to
explain what diff. aspects of cpu do, what is stepping and all that.
especially for intel but also for other architectures.
Thanks
Jon
Stepping is Intel teminology for chip revisions - possibly other
manufacturers have used the same terminology. Intel documents the fixes,
or rather the bugs and work-arounds, for each stepping level in the
addendum to the particular processor's reference manual. Probably, I
haven't checked, this info is available in PDF format from the INTEL
website (http://www.intel.com).
IBM terminology for the equivalent of stepping level is EC level
(engineering change level).
To understand the fine detail of the intel stepping levels, in particular
the work-arounds, you'll need to be familiar with the processor
architecture to the extent an assembler programmer would be.
