    • A method and system are employed within a processor for performing page table walks on speculative software prefetch operations. The system includes a first fault register to store information associated with a faulting micro-op relating to a non-prefetch memory access operation and a second fault register to store information associated with a faulting micro-op relating to a prefetch memory access operation. Also included in the system is a first unit to determine whether a currently pending micro-op relates to a non-prefetch operation or a prefetch operation. The first unit is configured to drop the currently pending micro-op from a pipeline if (1) the currently pending micro-op relates to a prefetch memory access and (2) the currently pending micro-op has previously faulted.
    • 在处理器中采用方法和系统,用于在推测性软件预取操作上执行页表行走。 该系统包括第一故障寄存器,用于存储与非预取存储器访问操作相关的故障微操作的信息,以及第二故障寄存器,用于存储与预取存储器访问操作相关的故障微操作相关的信息。 还包括在系统中的是确定当前待定的微操作是否涉及非预取操作或预取操作的第一单元。 如果(1)当前待处理的微操作与预取存储器访问相关,则第一单元被配置为从流水线中删除当前待处理的微操作;以及(2)当前待处理的微操作先前已经发生故障。
