Speaking of error checking. I wonder how many of the manufacturers of
computers using memory caching use parity checking on the cache memory
as well as the main memory? A lot of 386 machines have larger cache
memories than the original PC had as main memory. Not only the data in
the cache, but the translation addresses. And if the processor has
loadable microcode how about on the microcode control store?
Personally if my life depended on it I'd prefer having redundant computers
to having a lot of error checking in a single computer. And if the
consequences are really disastrous, I'd have two or more different kinds
of computers running different programs written by different teams.
