The x86 protection model is notoriously complex, with four privilege rings, segmentation, paging, call gates, task switches, and virtual 8086 mode. What's interesting from a hardware perspective is how the 386 manages this complexity on a 275,000-transistor budget. The 386 employs a variety of techniques to implement protection: a dedicated PLA for protection checking, a hardware state machine for page table walks, segment and paging caches, and microcode for everything else.

靳良给数据企业算了一笔账：存量负荷10.5万千瓦，年用电量7.4亿千瓦时，通过与风电场双边交易“虚拟直供”方式供电；增量负荷19.2万千瓦，年用电量15.5亿千瓦时，光伏发电时段采用“物理直供”方式供电，光伏不发电时段通过与风电场双边交易“虚拟直供”方式供电。
