内容記述
Enhancement of mobile computers requires the achievement of high performance computing with low energy consumption. Variable stages pipeline (VSP) architecture, which reduces energy consumption and improves execution time by dynamically unifying the pipeline stages, is proposed to achieve this requirement. To unify the pipeline stages dynamically, the VSP processor adopts a special pipeline register called the LDS-cell (Latch D-flip flop Selector-cell). The LDS-cell does not only unify the pipeline stages but can also prevent glitch propagation caused by stage unification under low energy mode. In this paper, the design of the fabricated VLSI of the VSP processor chip on a 0.18 ?m CMOS technology is described. Evaluation of the energy consumption shows that the VSP processor can achieve 13% Iess eners/ consumption than the conventional approach.
