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.

What problems must be solved in order to create a method for changing cache that is compatible with any particular address sequence?
How does a cache function when it stores data in a wholly associative format?
A 2-way set-associative cache consists of four sets. Main memory contains 2K blocks of 8 bytes each and byte addressing is used.Q.) Compute the hit ratio for a program that loops three times from addresses 0x8 to 0x33 in main memory. You may leave the hit ratio in terms of a fraction.
How many 16-byte cache blocks are needed to store all 32-bit matrix elements being referenced?
A cache is organized as a 4 way set associative cache Each set's cache line consists of 4 words (meaning there are 16 bytes per line, for each set of the cache). Each set individually has one Valid bit, and one Dirty bit, for each line. The tag field of this cache is 8 bits wide. The address is 32 bits wide. Question 1c) What is the cache size? (Meaning the number of kilobytes of data being stored in this cache, ignoring the tag, dirty, and valid bits) Question 1d) If this same sized cache (meaning the number of kilobytes of the data part from the question 1c above) are instead organized as a direct mapped cache, what is the total number of 'memory bitcells' needed to design this cache instead (meaning how many bitcells including the tag, dirty, and valid bits? (Assume that the number of cache lines are not changing and that all the bytes of all four sets are now coalesced into one set, thus making it a direct mapped cache)
Suppose a computer using fully associative cache has 220220 words of main memory and a cache of 128 blocks, where each cache block contains 16 words. (a) How many blocks of main memory are there? (b) What is the format of a memory address as seen by the cache, that is, what are the sizes of the tag and word fields? (c) To which cache block will the memory reference 01D872_{16}01D872_{16} map?
6. For a direct mapped cache comprising 16 single word blocks answer the following questions.

How many offset bits are there? How many tag bits are there?
