I recall that MIPS could emulate a TLB table walk in something like

Would would have been a significant fraction (25%?)of the
total memory available on a R3k based system in 1990.

I heard numbers in the 10% range, so we are within a factor of 2 in
our memory. The smaller main memory was, the less can be co-resident
and the smaller the effective table size.
