Discuss the concept of Cache Memory and Virtual Memory
as applied to storage in a
computer system.
`Hey,
Note: If you have any queries related to the answer please do comment. I would be very happy to resolve all your queries.
Cache memory increases the accessing speed of CPU. It is not a technique but a memory unit i.e a storage device. In cache memory, recently used data is copied. Whenever the program is ready to be executed, it is fetched from main memory and then copied to the cache memory. But, if its copy is already present in the cache memory then the program is directly executed.
Virtual Memory increases the capacity of main memory. Virtual
memory is not a storage unit, its a technique. In virtual memory,
even such programs which have a larger size than the main memory
are allowed to be executed.
Kindly revert for any queries
Thanks.

16 It is known that computer system programs use 32-bit virtual addresses to access storage units. If the physical memory space of the computer system is 1GB, and the paging management mechanism is adopted, the page size is 4KB, and each page table entry is 4B. If only one level of page table is used to realize the mapping from virtual address to physical address, how much memory space does the page table occupy? A. 1MB B. 4KB C. 1KB...
Several forms of storage can be identified in typical computer systems: registers, main memory, cache memory, read-only memory, magnetic disk and tape storage. Briefly describe each of these with particular reference to its access time, the life time of the data it stores, its typical usage and frequency of access
A computer system has the following memory timing clock cycle (CC) specification: Cache access time 1 CC, Main memory access time 100 CC, and Virtual memory access time 100,000 CC. Find the ratio of Average Memory Access Times (AMAT) of the following two programs and determine which program executes faster: B5. cache miss rate : 25% Main memory miss rate Program B: Cache miss rate 20% Main memory miss rates 10% 5%

Question 25 Answer the following about the memory system with virtual memory. Select True/False (T/F) for each statement. It's possible to get: TLB hit/Cache miss. (Select] T It's possible to get: TLB miss/Page Table hit/Cache hit ( Select ] F It's possible to get: TLB miss/Page Table hit/Cache miss. [Select ] It's possible to get: TLB miss/Page Fault/Cache hit. (Select]
(a) A computer system with a cache memory has an average memory access time of TM= 50 ns with a hit ratio of h= 80%. The primary memory access time is TP=120 ns. What is the cache memory access time, TC?
Memory Hierarchy and Cache Consider a computer with byte-addressable memory. Addresses are 24-bits. The cache is capable of storing a total of 64KB of data, and frames of 32 bytes, Show the format of a 24-bit memory address for: a- Direct mapped cache b- 2-way associative cache c- 4-way associative cache d- For each type of cache above, indicate where would the reference memory address 0DEFB6 map
Many of the policies and features that determine how a hierarchy (cache, virtual memory) functions are similar qualitatively. Discuss the common operational alternatives for memory hierarchies by answering the following questions. 1.Where can a block be placed? 2.How is a block found? 3.Which block should be replaced? 4.What happens on a write? 5.Identify and define the three Cs.
11. In a paged virtual memory system, can the computer 's physical memory address space be larger than a process's virtual memory address space? Explain your answer. (Note: A computer 's "physical memory address space" is the number of bits for the frame number plus the number of bits foir the offset. A process's "virtual memory address space" is the number of bits for a page number plus the number of bits for the offset.)
Suppose a computer using set associative cache has 216 words of main memory and a cache of 32 blocks, and each cache block contains 8 words. 3. If this cache is 2-way set associative, what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, set, and word fields? If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?...
Question 31 supus Given a computer using a byte-addressable virtual memory system with a two-entry TLB, a 2-way set associative cache, and a page table for a process P. Assume cache blocks of size 16 bytes. Assume pages of size 32 bytes and a main memory of 4 frames. Assume the following TLB and page table for Process P: TLB 03 4 هما 0 1 2 3 4 5 6 7 Page Table f Vali d 1 1 0 2...
