Suppose a computer using direct mapped cache has 4G Bytes of main memory and a cache of 256 Blocks, where each cache Block has 16 Words, and Word Size is 4 Bytes.   a)How many blocks of main memory?   b)What is the format of a memory address as seen by the cache (Tag, Block and Word fields)?   c)To which cache block will the memory reference 0000146A in Hex?

In a certain computer, the virtual addresses are 32 bits long and the physical addresses are 48 bits long. The memory is word addressable. The page size is 16 kB and the word size is 2 bytes. The Translation Look-aside Buffer (TLB) in the address translation path has 64 valid entries. Hit ratio of TLB is 100% then maximum number of distinct virtual addresses that can be translated is K.

Suppose we have a byte-addressable computer with a cache that holds 8 blocks of 16 bytes each.  Assuming that each memory address has 16 bits, to which cache block would the hexadecimal address 0x13F map if the computer uses direct mapping? Blocks are numbered starting at 0.

If we had a computer that can only address data in bytes, but it has fully associative mapping, 16-bit main memory addresses, and 32-bit cache memory blocks. If each block is 16 bytes in size, then...(a) Count the number of bytes in the offset field.The tag field's size in pixels must be calculated (b).

Suppose we have a byte-addressable computer with a cache that holds 8 blocks of 4 bytes each.  Assuming that each memory address has 8 bits, to which cache block would the hexadecimal address 0x2D map if the computer uses direct mapping? Blocks are numbered starting at 0

Suppose a computer using fully associative cache has 224 bytes of byte-addressable main memory and a cache of 128 blocks, where each block contains 64 bytes.Q.) To which cache block will the memory address 0x01D872 map?

Question 23 Some portion of cache system A represented below. The system is byte-addressable and the block size is one word (4 bytes). The tag and line number are represented with a binary numbers. The contents of words in the block are represented with hexadecimal. Tag 10 1000 0100 1001 10 1000 0100 1001 10 1000 0100 1001 10 1000 0100 1101 Line Number 0110 1101 0110 1110 0110 1111 B1 FF B8 A1 FF B8 B1 FF B8 A1 FF B8 B1 FF B8 0111 0000 1. What is the size of the main memory of this system? 2. What is the size of the cache memory of this system? 00 Word within block 2016 6116 C116 2116 01 10 11 3216 7216 C216 D216 4216 8216 4116 A216 E216 9216 5216 B216 3. If the CPU requests to read memory address A1 25 BA, what data does the CPU receive? 4. If the CPU requests to read memory address A1 35 C2, what data does the CPU receive? 5. If we access memory in the following order in cache system A: A1 FF B8 how many cache misses would occur for the data request?

Suppose a computer using fully associative cache has 224 words of main memory and a cache of 512 blocks, where each cache block contains 16 words. How many blocks of main memory are there? What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag and offset fields? To which cache block will the memory reference 17042416 map?
