If I have a problem set like so:
Below is a list of 64-bit memory address references, given as
word addresses.
3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253
5.2.1
BLOCK SIZE: 1 word
CACHE SIZE: 16 1-word blocks
a) 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.
b) For each of these references, identify the binary address, the
tag, and the index given a direct-mapped cache with two-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.
c) You are asked to optimize a cache design for the given references. There are three direct-mapped cache design possible, all with a total of eight words of data. Which cache provides best performance?
a. C1 has 1-word blocks
b. C2 has 2-word blocks
c. C3 has 4-word blocks
If you have any doubt comment down.. Also please upvote thanks..

use the following list of 32 bit memory address references, given as word addresses. Note that you will need to convert them to binary: 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 4. Assume a direct-mapped cache with 16 one-word blocks. For each reference, list the binary address, the tag, the index, and if the reference is a hit or a miss, assuming the cache is initially empty.
Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses. 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-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...
Please help with this Below is a list of 32-bit (1 word) memory address references a program makes, given as word addresses (not byte addresses): 2, 4, 5, 4, 6, 4, 12, 13, 2, 13, 4, 253 For each of these references, identify the tag and index, given a 16 word, direct-mapped cache which has 8 two-word blocks. Also, list if each reference is a hit or a miss, assuming the cache is initially empty. Your answer should be a...
Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of memory address references, given as word addresses (in decimal, the byte-offset bits have been excluded from addresses). 1, 4, 8, 5, 20, 17, 4, 56, 9, 10, 43, 5, 6, 9, 17 For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-word blocks (two words per block) and a total size of 8 blocks....
Using the sequences of 32-bit memory read references, given as word addresses in the following table: 6 214 175 214 6 84 65 174 64 105 85 215 For each of these read accesses, identify the binary address, the tag, the index, and whether it experiences a hit or a miss, for each of the following cache configurations. Assume the cache is initially empty. A direct-mapped cache with 16 one-word blocks. A direct-mapped cache with two-word blocks and a total...
Here is a series of address references given as word addresses: 1, 4, 8, 5, 20, 17, 19, 56, 9, 11, 4, 43, 5, 6, 9, 17. For each of the following cache design, label each reference as a hit or a miss and show the final contents of the cache. Assume the caches are initially empty. - Direct mapped with four-word blocks and total size of 16 words.
Question 3: Consider a 32-bit physical address memory system with block size 16 bytes and a 32 blocks direct mapped cache. The cache is initially empty. The following decimal memory addresses are referenced 1020, 1006, 1022, 5106, 994, and 2019 Map the addresses to cache blocks and indicate whether hit or miss. Note: You must use the hexadecimal approach in solving this question. You must also show the computations of dividing the memory address into tag bits, cache index bits,...
Assuming a direct-mapped cache with 4 four-word blocks that is initially empty, label each reference in the list as a hit or a miss and show the final contents of the cache. The following is a sequence of address references given as word addresses. 1, 5, 8, 4, 17, 19, 20, 6, 9, 8, 43, 5, 6, 21, 9, 17 Reference Hit or Miss Miss 17 19 20 43 Wordo Wordi Word2 Word 3 Block
Please answer all parts correctly and show your work 3- for a direct mapped cache design with a 32 bit address, the following bits of address are used to access the cache Tag Index Offset 31-10 9-5 4-0 Starting from power on, the following byte addressed cache reference are recorded. Address 0 16 132 232 160 1024 30 140 3100180 2180 d. How many blocks are replaced e. What is the hit ratio f. List final state of the cache,...
We have a 4 KB direct-mapped data cache with 4-byte blocks. Consider this address trace: 0x48014554 0x48014548 0x48014754 0x48034760 0x48014554 0x48014560 0x48014760 0x48014554 For this cache, for each address in the above trace, show the tag, index and offset in binary (or hex). Indicate whether each reference is a hit or a miss. What is the miss rate?
