Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

Question

It should be clear that disk striping can improve data transfer rate when the strip size
is small compared to the I/O request size. It should also be clear that RAID 0 pro-
vides improved performance relative to a single large disk, because multiple I/O re-
quests can be handled in parallel. However, in this latter case, is disk striping
necessary? That is, does disk striping improve I/O request rate performance com-
pared to a comparable disk array without striping?

Please help me with this computer architecture homework
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 8 bytes. Assume pages of size 16 bytes and a main memory of 4 frames. Assume the following TLB and page table for Process P: TLB 0 Vali d 0 1 1 1 2 0 3 1 4 1 5 0 6 0 7 0 Assume process P generates a memory request with virtual address Ox12. What is its corresponding physical address? You may represent the address in binary or hexadecimal notation. 3 3 0 2 1 4 Page Table f 1
1. What is the difference (or differences) between a TLB and on-chip cache? a. The TLB is direct-mapped, while caches are set associative. b. The TLB is indexed by the virtual address, while caches are Indexed by the physical address. c. The TLB stores virtual-to-physical address translations, while caches store data. d. The TLB can be slow, but caches need to be fast. e. The TLB stores instructions, while caches store data. 2. Say we have two mutexes, implemented with binary semaphores, and two threads which access them. Which of the following can cause deadlock a. The threads lock the mutexes in the same order. b. The threads lock the mutexes in a different order. C. The threads unlock the mutexes in the same order. d. The threads unlock the mutexes in a different order.

Q4 consider a computer with the following characteristics: total of 4 MB of a byte-addressable- main memory; block size of 64 bytes; and cache size of 256 kB. O a. For the main memory addresses of D0005, 512C7, and 7BAAA, give the O corresponding tag, cache line address, and word offsets for a direct-mapped cache. b. Give any two main memory addresses with different tags that map to the same cache slot for a direct-mapped cache.
Answer the following: A section of the memory space with the address from 0x6000 to 0x9FFF needs to be fully partitioned to two peripherals with the same memory size. The first peripheral's address starts at Ox6000 and ends at Ox . The second peripheral's address starts at Ox ends at Ox9FFF. and In embedded programming, let i = 13, then j =i<< 2; we have j = 0x wise operation, let i = 0x00ff and then i &= ~0x0010, we have i = Ox . And for bit-
