A log entry has how many fields? This programme calculates average cache miss rates per entry using 64-byte blocks without prefetching.
Step by step
Solved in 3 steps
- A cache is set up with a block size of 32 words. There are 64 blocks in cache and set up to be 4-way set associative. You have byte address 0x8923. Show the word address, block address, tag, and index Show each access being filled in with a note of hit or miss. You are given word address and the access are: 0xff, 0x08, 0x22, 0x00, 0x39, 0xF3, 0x07, 0xc0.How many fields can the specified log processing function access in a log entry? Calculating average cache miss rates per entry using 64-byte blocks and no prefetching is done using the following codeIs there a way to find out which parts of a log entry a certain log processing function can read? The following code determines the typical number of cache misses per entry while using 64-byte cache blocks and no prefetching.
- How does a fully associative data format that is used to store data in a cache work?This function will be able to look at which fields in a log entry that it needs to. When you use 64-byte cache blocks and don't prefetch, the following code calculates the average number of cache misses for each entry in the cache.For a direct-mapped cache design with 64-bit addresses, the following bits of the address are used to access the cache: Tag Index Offset 63-13 12-4 3-0 a. What is the cache block size (in bytes)?b. What is the cache size (in bytes)?c. What is the total number of bits (including valid bit, tag bits and data array bits) to implement this cache?d. For the same block and cache sizes, you want to implement a 4-way set-associative cache, what is the number of index bit and the number of tag bits?
- In the event of an unsatisfied cache request, what should happen to the block being sent to the main memory from the write buffer?Q2: a cache memory consists of 512 blocks, and if the last word in the block is 1111111. I the last Tag is 1111. Then the total number of words in main memory is Tags, and The main memory consists of blocks. The total number of bits in address fields i . where number of bits for tag field is .... and the remaining number of bits for word field i ..A message slot is a cache line that contains status flags and the message itself. The state can be empty or ready, and communication occurs through a single cache line. Both the sender and the receiver write the message to the cache line. The receiver updates the state from empty to ready, then polls the cache line in a loop waiting for the sender to send a message. The sender waits in a tight loop until the receiver acknowledges the cache line, changes the state from ready to empty, and acknowledges receipt. Explain that the system uses a snooping cache coherence protocol and describe the cache-coherence transaction taking place on the coherence bus when a message transfer occurs.

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.

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?A 2-way set associative cache consists of four sets. Main memory contains 2K blocks of eight words each. Show the main memory address format that allows us to map addresses from main memory to cache. Be sure to include the fields as well as their sizes. Compute the hit ratio for a program that loops 6 times from locations 8 to 51 in main memory. You may leave the hit ratio in terms of a fraction. Please show details how you obtain the result.
