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.。关于这个话题，WPS官方版本下载提供了深入分析

Indie director Jim Jarmusch has forged his reputation on intimate and immaculately cool character-driven dramas like Dead Man, Broken Flowers, Only Lovers Left Alive, and the unconventional zombie dramedy The Dead Don't Die. He has a way of taking famous actors and transforming them in ways we've never seen before. So frankly, we were giddy about this combination of ensemble cast and Jarmusch before we even got to the plot.*
