Assume you have a cache/memory system with the following characteristics: Size of a word: 4 bytes Size of a cache block: 4 words Size of cache: 16 words Associativity of the cache: 2-way Set Associative. Replacement Policy: LRU (Least Recently Used) How many sets are present in this cache? Assume that the following word addresses are accessed as read in the following order. In each case, say whether or not the corresponding access is a hit or a miss. If it is a miss, specify what kind of miss it is. Words accessed: 4, 3, 6, 8, 1, 24, 16, 19, 20, 19, 1. What is the miss rate for this cache and this pattern of word accesses? Draw a figure showing the final state of the cache.

Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.
