I suppose having some sort of minimum granularity for the MMU makes a lot of sense, but above that point, why limit the "steps" or the maximum? why not 4KB+2 for example (4098)? For the sake or discussion, let's say I have 128GB ram and 50TB page file, can that work? Why is a fixed-size page more efficient, is it because of offset calculations being simpler arithmetic operations? I figured the TLB is (or can be) a simple (large) table implemented in hardware, the simplicity translating into O(N) complexity. I am suspecting it might have to do with hardware cost? |
