### Cache Replacement Policies and Memory AccessesA memory system has 4 KB byte-addressable main memory and a **2-way set associative** cache that consists of 8 blocks with 32 bytes per block. Assuming the cache is initially empty, determine the number of cache misses that result from the following sequence of memory accesses assuming the two cache replacement policies below:#### Memory References:0x652, 0x643, 0x6D5, 0x6C7, 0x65D, 0xA49, 0x644, 0x6C81. **Assuming a FIFO replacement policy:**2. **Assuming a Least Frequently Used (LFU) replacement policy:**In this problem, the memory references will be analyzed to determine the number of cache misses for each of the two cache replacement policies: FIFO and LFU. Each memory access may result in a cache hit or a miss, and the replacement policy will dictate how cache blocks are replaced if a miss occurs and the cache is full.In a **FIFO (First-In, First-Out)** replacement policy, the oldest cache block is replaced first.In a **Least Frequently Used (LFU)** replacement policy, the least frequently accessed cache block is replaced first.By following through the sequence of memory references and applying each replacement policy, we can determine the number of cache misses for each policy.

A cache memory stores frequently/recently used data and instructions during instruction execution. With the aid of a diagram explain how the main memory is divided into blocks and how these blocks of main memory are allocated to the lines of cache using direct mapping.
For a processor with a 32-bit address bus and a 64-bit data bus, 32 bytes of "line size" and a total capacity of 2MByte "cache" memory are used. For each of the "cache map" techniques given below, find how the physical address will be partitioned and how many bits will be used for each partition. a) 2-way set associative b) 4-way set associative
Please Solve, thank you sir
Assume that a system is using write-though cache. It has 70% write hits. The cache operates in look-aside mode with a read-hit ratio of 80%. The program run on the system is such that it has memory reference for read 70% of time and for write is 30%. The main memory cycle time is 100ns and the cache access is 20ns.(Further assume we are using no write allocate policy) Difference between average write access time and average read access time is (in ns).

Q4 consider a computer with the following characteristics: total of 4 MB of a byte-addressable- main memory; block size of 64 bytes; and cache size of 256 kB. O a. For the main memory addresses of D0005, 512C7, and 7BAAA, give the O corresponding tag, cache line address, and word offsets for a direct-mapped cache. b. Give any two main memory addresses with different tags that map to the same cache slot for a direct-mapped cache.
