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.

英伟达的这份战略野心，也体现在合作阵营的选择上。英国电信、德国电信、软银、SK电信，加上爱立信、诺基亚、思科等企业，全部来自美国核心盟友体系。这样高度定向的合作结构，释放出明确的战略信号：AI-RAN不只是单纯的技术路线，更是基于“可信供应链”“盟友协同”的基础设施重构计划。这套方案与美国FutureG、OCUDU等政府政策倡议联动，更让这一布局带上了浓厚的地缘政治与政策导向色彩。。PDF资料对此有专业解读
