处理器模块奔腾Pro,是奔腾体系结构中的一种。它采用了14级超流水线设计,可以解耦处理不同的指令,并具有8KB的内存指令缓存。奔腾Pro有三个指令解码器,其中通用解码器可以解码任何x86指令,而另外两个简单解码器只能解码简单的x86指令。奔腾Pro的解码器能力不平等,限制了同时解码多条指令的能力,从而影响了超标量的执行。

The processor module Pentium Pro is a type of Pentium architecture. It adopts a 14 level ultra pipeline design, which can decouple and process different instructions, and has an 8KB memory instruction cache.
The Pentium Pro has three instruction decoders, among which the universal decoder can decode any x86 instruction, while the other two simple decoders can only decode simple x86 instructions. The unequal decoder capabilities of Pentium Pro limit the ability to simultaneously decode multiple instructions, thereby affecting the execution of superscalars.
