....(MIPS 8957278 and CCR 8902536) A.T. T. Bell Laboratories, Cray Research Foundation and Digital Equipment Corporation. 2 1. Introduction Commercial and academic microprocessor architectures are increasingly incorporating caches on the processor chip itself to avoid off chip latencies [3, 6, 8, 12]. These on chip caches are currently small, but the trend is toward larger sizes to hide relatively slower off chip memory speeds; thus, these chips devote an increasing portion of their area to the memory (tags and blocks) of the cache. As cache chip area becomes large, so will the fraction of ....

....power dissipation of 25 with an accompanying small increase of 5 in area. Finally, we explore how this technique can be extended in new directions to realize additional power savings. 2 Background 2. 1 Two phase clocking Many large VLSI circuits use a two phase non overlapping clocking scheme [13, 14, 15]. This method of clocking minimizes clock skew problems associated with a single phase scheme at the expense of higher area. With a two phase clocking scheme, timing problems can be eliminated just by increasing the clock period, because there is no bilateral constraint on the clock waveform as ....
