Consider the hierarchical pagi

[问答题]
Consider the hierarchical paging scheme used by the VAX architecture. How many memory operations are performed when an user program executes a memory load operation?

推荐
When a memory load operation is performed, there are three memory operations that might be performed. One is to translate the position where the page table entry for the page could be found (since page tables themselves are paged). The second access is to access the page table entry itself, while the third access is the actual memory load operation.
