           现代处理器采用多种微结构设计技术挖掘指令级并行性，包括指令流水线、多发射、动态调度、寄存器重命名、转移猜测等技术。指令流水线重叠执行多条不相关的指令；多发射技术允许一个时钟周期执行多条指令，类似于“多车道”；动态调度允许后续指令越过前面被阻塞的指令继续被调度执行，相当于允许“超车”；寄存器重命名主要解决RAW和WAW的假相关问题；转移猜测技术可以猜测分支指令的方向和目标，在分支指令还未执行完之前获取更多可执行指令，以减少控制相关造成的指令流水线阻塞。这方面的技术已经比较成熟。

这一段中可能存在笔误，寄存器重命名主要解决 WAR 和WAW的假相关问题，原文中写成了”寄存器重命名主要解决 RAW 和WAW的假相关问题“

确实是的，谢谢指正。
