While we are on the subject, can someone tell me why system designers
are assuming the followings?
1) Page size is fixed.
2) Paging policy does not change.
3) Virtual memory systems are 10% slower.
To prove that these assumptions are not always true, i am simulating
a demand paged machine ( a subset of 16k instructions ) with
1) Variable page size ( a multiple of 512 ).
2) Adaptive paging policy ( based on run time paging history ).
Before i get too much into this idea, i would like to hear from people
who have done similar studies.
