I want to be able to configure the cache so that it is used differently (either set-associative or to keep the question as precise as possible, specially in the title. A block of memory cannot necessarily be placed at an arbitrary location in the cache; it may be restricted to a particular cache line or a set of cache lines [1] by the cache's placement policy. so from these we got to know that 3 bits are required for adressing set offset. The trace size at the top of the file have to be changed accordingly as well. Simulates direct mapped, set associative, and fully associative cache types. The process that is being performed is filling the pixels of a fractal image. Note that certain combinations of these design parameters account for direct-mapped, set-associative, and fully associative caches: a cache with n sets of 1 block each is direct-mapped; For that reason, we settle for something in-between direct-mapped and fully associative caches: the set-associative cache.
