Problem 1: Short Answer [20 points] A. [7 points] Assume a pipelined processor with N pipeline stages. As we increase N, briefly explain that happens to the following (increase/decrease + 1 sentence reasoning) - Clock cycle time: - Cycles per instruction: Considering clock cycle time only, is there a limit or point of diminishing returns for the number of pipeline stages in a processor? Why? B. [7 points] Assume a first level data cache with capacity (C), associativity (A), and block size (B). Draw the expected effect on hit rate as C, A, and B increase respectively. In each case, we vary one of the three parameters, while the other two are kept constant. Mark one or two interesting points on the graphs with 3-4 words to provide some reasoning.
