[comp.arch] Question about Caches in Sun/Vax

hugo@quimby.dartmouth.edu (09/28/88)

Hi,

I was wondering if anyone knew anything about caches that might be
present in Vax 11-785 machines?

I was also wondering if the Sun 3 machines have any extra cache
hardware besides what is on the 68020.

Any info would be greatly appreciated.

Thanks,
Pete

The 200 series of Sun 3s have a large external virtual-address cache.  The
others -- the 180 and below -- have none, although they do have fairly
carefully optimized memory systems.
