A computer with a 32?bit address architecture has a memory management system with single?level 4 KB page tables. How much memory space must be devoted to the page tables?
What will be an ideal response?
The address bus has 32 address lines A31 to A00. Address lines A11 to A00 select a location within a page, which
leaves address lines A12 to A31 to select a page. A translation table would require 20 address lines to translate
the 220 possible pages each containing an address translation. If the physical address space is the same as the
logical address space and a pointer is 20 bits (three bytes), then 3 × 220 bytes would be required (an impossibly
large value).
