Question 16138 – Cache

Which one of the following statements is FALSE?

Correct Answer: C

Question 17 Explanation:

(A) True: The tlb performs the address search in parallel to memory.
(B) True: TLB hit implies no page fault. Hence, the page-frame will always be in main memory.
(C) False: Inverted page table depends on the size of the process. Hence, the memory access time also varies.
(D) True: Collision resolution techniques are applied. Hence, the each address may take different time.

The TLB performs an associative search in parallel on all its valid entries using page number of incoming virtual address.

If the virtual address of a word given by CPU has a TLB hit, but the subsequent search for the word results in a cache miss, then the word will always be present in the main memory.

The memory access time using a given inverted page table is always same for all incoming virtual addresses.

In a system that uses hashed page tables, if two distinct virtual addresses V1 and V2 map to the same value while hashing, then the memory access time of these addresses will not be the same.
