This paper presents an analytical study of speed-cost tradeoffs in memory hierarchy design. It develops an optimization criterion by which average access time, i. e., memory system delay, is minimized under a cost constraint for a hierarchy with given memory sizes and access probabilities. Using a power function assumption relating speed and cost of memory units, it is shown that an optimized hierarchy has the property of balanced cost and delay distributions, in that each memory unit makes the… CONTINUE READING
