Three microcode cycles for the writeback alone. That's acceptable because segment loads are already expensive multi-cycle operations, and the designers likely expected them to be infrequent -- most programs load their segments once at startup and never touch them again. Page translations happen on every memory access, so the same approach would be ruinous. Hence the fully autonomous hardware walker.
数据显示,2025年中国自动驾驶领域总投入预计达700-750亿元,同比增长40%。但整个中国汽车行业利润率只有4.1%,处于历史低点。利润增长赶不上研发投入增长,尤其对于还在亏损中的车企来说,L3还是L4?曾经是两者都要、循序渐进,现在成了二选一的选择题。。关于这个话题,爱思助手下载最新版本提供了深入分析
