Given a computer with a memory system having a40_bit address, a cache consisting of 8192 blocks each is 32 words. For thefollowing cache types: Direct Mapped (DM), Fully_ associative (FA), Two_way set associative (2_way), Four_way set associative(4_way), Eight_way set associative (8_way), calculate the following values as specified.(Use paper and pencil to do needed calculations and write only the final answer in the given blank space).1) DM: The size of the index field = Blank 1bits2) 2_way: The size of the index field =Blank 2bits3) 4_way: The size of the index field =Blank 3bits4) 8_way: The size of the index field =Blank 4bits5) The size of the offset field = Blank 5bits6) DM: The size of the tag field =Blank 6bits7) 2_way: The size of the tag field =Blank 7bits8) 4_way: The size of the tag field =Blank 8bits9) 8_way: The size of the tag field =Blank 9bits10) FA: The size of the tag field =Blank 10bits

Q e
Suppose a byte-addressable computer using set associative cache has 224 bytes of main memory and a cache size of 64K bytes, and each cache block contains 32 bytes. a) 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 offset fields? b) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?
Q5 Cache Performance Analysis This challenging question tests your understanding of cache. Consider the following C code: int A[16]; int B[16]; int m; ... //A large chunk of code that does NOT access //arrays A and B. ... for (int i=0; i<10; i++) { for (int j=0; j<16; j++) { B[j] = m * A[j] + B[j]; } } Assume this program runs on a 32-bit machine, i.e., the CPU loads/stores 4 bytes from memory in one go. This machine has a 16-bit memory address, and each memory block stores 16 bytes. This machine has a direct-mapped data cache with 16 cache lines. Array A starts at address 0, and B starts at address 256 - both arrays begin at a memory block boundary. Each element of arrays A and B occupies 4 bytes. The values of i, j, and m are stored in CPU registers. Assume we change the cache configuration to be 2-way set-associative. This new data cache has 8 sets and 16 bytes per line. The cache uses a Least Recently Used (LRU) replacement policy. How many data cache misses (including…
Suppose a byte-addressable computer using set-associative cache has 216 bytes of main memory and a cache of 32 blocks, and each cache block contains 8 bytes.Q.) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?
CA_6 We study the properties of cache memory, and for reasons of easier design and efficient circuits, we assume that the cache capacity is 2i Bytes, and cache line size is 2j Bytes, with i and j being natural numbers: (a) How many bits should the tag field have? And can the tag field contain 0 bit (i.e., be empty)? Elaborate (b) Repeat the above for the index field. (c) Repeat the above for the byte-offset field. (d) Finally, depict a figure showing a cache line, indicate what fields it possibly has, state the possible sizes of these fields, and explain the uses of these fields.
Computer science homework Please help me with this homework question.
Suppose a byte-addressable computer using set associative cache has 2^24 bytes of main memory and a cache size of 64K bytes, and each cache block contains 32 bytes. a) 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 offset fields? b) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?
Convert the following Compact Memory Notation diagram into an Array Memory Notation diagram. Assume the addresses are 4-bit binary values and the data are 8-bit binary values. Hint: The solution to this question is simply the reformatted diagram in Array Notation.
Computer Science You are given a cache that has 16 byte blocks, 512 sets, and is 2-way set associative. Integers are 4 bytes. Give the C code for a loop that has a 100% miss rate in this cache but whose hit rate rises to almost 100% if you double the size of the cache. Do not assume the starting indexes of any arraysarrays.
Question 4
.2: Below is a list of 32-bit memory address references, given as word addresses. 3, 180, 43, 2, 191, 88, 253 For each of these references, identify the binary address, the tag, and the index given a direct- mapped cache with 16 one-word blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with 2-word blocks and a total size of 8 blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with 4-word blocks and a total size of 8 blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty.
What memory blocks will be in the cache after the last address has been accessed?
