摘要

22nm全数字动态自适应时钟分布减轻了高频电源电压(VCC)下降对微处理器性能和能效的影响。硅测量表明，当电压降低10%时，在1.0V时，同时吞吐量提高14%，能耗降低3%，在0.6V时，分别降低31%和15%。

A 22nm dynamically adaptive clock distribution for voltage droop tolerance

A 22nm all-digital dynamically adaptive clock distribution mitigates the impact of high-frequency supply voltage (VCC) droops on microprocessor performance and energy efficiency. Silicon measurements demonstrate simultaneous throughput gains and energy reductions ranging from 14% and 3% at 1.0V to 31% and 15% at 0.6V, respectively, for a 10% VCC droop.
