Re: Why Did No Core Machines Have Cache ???

When I say "cache", I'm referring to memory that
implements an address-match range greater than
its physical implementation, and I'm referring
to an address-match capability at the word or
block level, not page-level. That excludes the
CDC 6600 memory hierarchy of LCS/ECS and paging
hardware like that on the SDS 940.

That type of cache, as noted in another reply, was used by IBM on the
IBM 360/85, a core machine. Later, it was also used on the IBM 360/195,
a large machine which took the existing 360/91 design, implemented in
ASLT, and converted it to monolithic, and added cache as well. This,
too, was a core machine.
