Below is a list of 32-bit memory address references, given as memory addresses. 12, 720, 172, 8, 764, 352, 760, 56, 724, 176, 744You would like to access a cache with the given memory addresses. The size of cache is 23 = 8-blocks. Your task is to: (1) find out the binary address, (2) fill out the tag and index for each memory address and (3) indicate whether the access is hit or miss in the following table:
The following table gives the parameters for a number of differentcaches. For each cache, fill in the missing fields in the table. Recallthat m is the number of physical address bits, C is the cache size(number of data bytes), B is the block size in bytes, E is theassociativity, S is the number of cache sets, t is the number of tag bits, S is the number of set index bits, and b is the number of block offset bits.
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.
Q.A direct-mapped cache consists of 8 blocks. Byte-addressable main memory contains 4K blocks of 8 bytes each. Access time for the cache is 22ns, and the time required to fill a cache slot from main memory is 300ns. (This time allows us to determine that the block is missing and bring it into cache.) Assume that a request is always started in parallel to both cache and to main memory (so if it is not found in cache, we do not have to add this cache search time to the memory access). 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.Q.) Compute the hit ratio for a program that loops four times from addresses 0x0 to 0x43 in memory.

Show the main memory address format, which allows us to map addresses from main memory to cache. Be sure to include the fields as well as their sizes.
A computer uses a set-associative cache with 8-blocks per set. How many bits will be used for the counter to apply the (LRU algorithm)? Explain your answer. The following blocks are referenced by the CPU and to be fetched from the RAM to the cache sequentially: (i j k L L j m j n L m j m L k S j P i O k) Assume that the cache set is empty and all the above blocks can be inserted into the set. Use the LRU algorithm to fill in the following table that describes the status of the cache locations for each called block.
6 Recall that we have two write policies and two write allocation policies, and their combinations can be implemented either in L1 or L2 cache. Assume the following choices for L1 and L2 caches: L1 L2 Write through, non-write allocate Write back, write allocate 6.1 Buffers are employed between different levels of memory hierarchy to reduce access latency. For this given configuration, list the possible buffers needed between L1 and L2 caches, as well as L2 cache and memory. 6.2 Describe the procedure of handling an L1 write-miss, considering the components involved and the possibility of replacing a dirty block. 6.3 For a multilevel exclusive cache con guration (a block can only reside in one of the L1 and L2 caches), describe the procedures of handling an L1 write-miss and an L1 read-miss, considering the components involved and the possibility of replacing a dirty block.
