- Is 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.To what extent does the specified log processing function have access to each field of a log entry? The following code estimates the average number of cache misses per entry while using 64-byte cache blocks and no prefetching.To what extent may a certain log processing function access the various components of a log entry? The following code determines the median number of cache misses per entry while using 64-byte cache blocks and no prefetching.
- This function will be able to determine the fields in a log entry it needs to look at in order to do its job properly. The following line of code computes the average number of cache misses for each item in the cache when 64-byte cache blocks are used without any prefetching being performed by the program.A direct-mapped cache consists of 16 blocks. A byte-addressable main memory contains 4K blocks of 16 bytes each. Access time for the cache is 30 ns and the time required to fill a cache slot from main memory is 250 ns. Assume a request is always started in sequential to cache and then to main memory. If a block is missing from cache, the entire block is brought into the cache and the access is restarted. Initially, the cache is empty. a) 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. b) Compute the hit ratio for a program that loops 4 times from locations 0 to 42 (base 10) in memory. c) Compute the effective access time for this program.How much access does a particular log processing function have to the different parts of a log entry? The following line of code calculates the median number of cache misses per entry when 64-byte cache blocks are being used and no prefetching is taking place.
- 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?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 code.How much of a log entry's data can a particular log processing function access? The following code determines the typical number of cache misses per entry while using 64-byte cache blocks and no prefetching.
- In the event of an unsatisfied cache request, what should happen to the block being sent to the main memory from the write buffer?The padding technique is effective to remove false sharing, but it requires consuming more memory in order to fill in the first cache line to enforce y to move to another cache line. If the memory consumption is a concern, what would you suggest as an alternative possible solution the programmer can do to avoid false sharing?3. The series of memory address references given as word addresses are 122, 126, 126, 126, 116, 300, 116, and 118. Assume a direct-mapped cache with eight one-word blocks that is initially empty. Label each reference in the list as a hit or miss and show the contents of the cache with figure after each reference.
