软件版本：IntelArchitectureInstructionSetExtensionsandFutureFeaturesProgrammingReference（2023版）一、x86架构的历史背景 1、x86架构的历史可以追溯到1978年，当时英特尔推出了8086微处理器。这个16位的处理器设计通过后续的发展，成为了今天广义上所称的x86架构。虽然“x86”最初专指16位的处理器，但随着时间...
Agner Fog, a Danish expert in software optimization ismaking a pleafor an open and standarized procedure for x86 instruction set extensions. Af first sight, this may seem a discussion that does not concern most of us. After all, the poor souls that have to program the insanely complex x86...
Threat on x86 instruction-set architecture; Advanced Micro Devices' introduction of the K6 3D processor; Cyrix's enhancement of its 6x86MX processor; Centaur's unveiling of its C6+ Pentium MMX-level CPU.Santoni, AndyInfoworld

指令集计算机,Complex Instruction Set Computer)。字组(word, 4字节)长度的存储器访问允许不对齐存储器地址,字组是以低位字节在前的顺序储存在存储器中。向前兼容性一直都是在x86架构的发展背后一股驱动力量(设计的需要决定了这项因素而常常导致批评,尤其是来自对手处理器的拥护者和理论界,他们对于一个被广泛认为是...
Many additions and extensions have been added to the original x86 instruction set over the years, almost consistently with full backward compatibility.[12] The architecture family has been implemented in processors from Intel, Cyrix, AMD, VIA Technologies and many other companies; there are also ope...

从现阶段的主流体系结构讲,指令集可分为复杂指令集和精简指令集两部分,而从具体运用看,如Intel的MMX(Multi Media Extended)、SSE、 SSE2(Streaming-Single instruction multiple data-Extensions 2)、SEE3和AMD的3DNow!等都是CPU的扩展指令集,分别增强了CPU的多媒体、图形图象和Internet等的处理能力。我们通常会把...
