The program should issue an error message and end if any of these tests fail, or if any of parameters a through d are omitted. Once parameters a through d have been validated, initialize the simulated memory system. Acquire memory for the cache and for the memory. You also may find it useful to establish a separate array for an associative memory. (These should all be separate variables.) Set all memory to zeroes, minus 1, or some other identifiable value. Then begin a processing loop. Read the input data and process all memory accesses. For write accesses, store the value in the cache.
