A computer uses 46—bit virtual address, 32—bit physical address, and a three—level paged page table organization.
The page table base register stores the base address of the first—level table T1 , which occupies exactly one page. Each entry of T1 stores the base address of a page of the second—level table T2. Each entry of T2 stores the base address of a page of the third—level table T3. Each entry of T3 stores a page table entry PTE. The PTE is 32 bits in size. The processor used in the computer has a 1 MB 16 way set associative virtually indexed physically tagged cache.
The cache block size is 64 bytes. What is the size of a page in KB in this computer? Send It! In the index allocation scheme of blocks to a file, the maximum possible size of the file depends on :. Increasing the RAM of a computer typically improves performance because:. Efficient implementation of multi-user support is no longer possible. The processor cache organization can be made more efficient now.
