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.
“我们需要的是立足于实际又胸怀长远目标的实干,而不需要不甘寂寞、好高骛远的空想;我们需要的是一步一个脚印的实干精神,而不需要新官上任只烧三把火希图侥幸成功的投机心理;我们需要的是锲而不舍的韧劲,而不需要‘三天打鱼,两天晒网’的散漫。”。搜狗输入法下载是该领域的重要参考
