A
set of dedicated registers
|
|
|
ä |
Reasonable
only for small page tables
|
|
|
ä |
Example:
|
|
|
16 bit logical address space
|
|
|
page size = 8K
|
|
|
page table size = 8
|
|
| ä |
Memory
|
|
|
ä |
use
a PTBR to point to the page table of the current
|
|
|
process
|
|
|
ä |
2
memory accesses are needed for every data access
|
|
|
ä |
speed
could be intolerable

Associative
registers
|
|
|
|
ä |
Associative
registers or translation look-aside buffers
|
|
|
(TLBs)
|
|
|
ä |
Only
few page table entries are kept in the associative
|
|
registers
|
|
|
ä |
The
hit ratio is the percentage of times that a page
|
|
|
number
is found in the associative registers
