The main rule for data access is max(CPL, RPL) ≤ DPL. For code transfers, the rules get considerably more complex -- conforming segments, call gates, and interrupt gates each have different privilege and state validation logic. If all these checks were done in microcode, each segment load would need a cascade of conditional branches: is it a code or data segment? Is the segment present? Is it conforming? Is the RPL valid? Is the DPL valid? This would greatly bloat the microcode ROM and add cycles to every protected-mode operation.

那么，为何会出现“腊梅”一词？“腊梅”的说法，宋代以后就有了。专家推测，大概率是因为蜡梅在寒冬腊月盛开，就有人写作了“腊梅”。腊月开花的既有蜡梅，也有梅花。因此“腊梅”一词不仅可以用来指代蜡梅，也可以用来指代在腊月开放的梅花。
