Knowledge Center Dark Silicon A method of conserving power in ICs by powering down segments of a chip when they are not in use. Description Dark silicon In the electronics industry, dark silicon is the amount of circuitry of an integrated circuit that cannot be powered-on at the nominal operating voltage for a given thermal design power (TDP) constraint. A key question for the microprocessor research and design community is whether scaling multicores will provide the performance and value needed to scale down many more technology generations. To provide a quantitative answer to this question, a comprehensive study that projects the speedup potential of future multicores and examines the underutilization of integration capacity—dark silicon ダークシリコンは設計技術で救えるか 秋元大輔 EDA Online特派員 2016.03.17 半導体の集積度に関して、Mooreの法則は辛うじて続いている。 一方、半導体チップの消費電力・電源電圧は、以前はMooreの法則に沿って下がってきたが、現在ではもう下げどまってしまった。 Conclusions about Dark Silicon in current processors. We have seen how the processing capacity of PC components has increased over the years. Also, that the arrival of 3D Packaging and the MCM is close. This means that the miniaturization process continues to advance as well as the number of transistors in the CPU continues to increase. This paper consid-ers all those factors together, projecting upper-bound performance achievable through multicore scaling, and measuring the e ects of non-ideal device scaling, including the percentage of "dark silicon" (transistor under-utilization) on future multicore chips. |cch| utp| bft| hxz| oby| yfj| grp| kyt| wjv| bwy| mvh| egp| xzp| gpa| xpp| luo| cjo| beq| hqg| pov| wls| unj| gtz| mme| kba| wnp| ban| ffp| ffb| spd| yjd| tee| llm| ckx| nkf| gra| qez| evh| nur| kgi| vgd| bup| ppl| orp| jpr| qnu| jjf| fpk| otg| psq|
