奔腾~*Ⅱ处理器家族的性能与上一代英特尔架构处理器相比有很大的提高,这种提高是基于高能奔腾~*处理器技术和英特尔MMX~(TM)媒体增强技术的紧密结合。得益于英特尔的MMX技术,使软件的性能更高,应用程序的性能有了发展余地。高能奔腾~*处理器的动态执行技术: ·多分支预测:通过几个分支预测程序的流向,加速处理器的工作流程。·数据流分析:通过分析指令间的数据依存关系,作出一个优化的重排序指令计划。·推测执行:推测地执行指令,基于这一优化了的安排,使处理器的超标量执行单元始终处于运行状态,从而提高整体性能
The performance of the Pentium-II processor family has greatly improved over the previous generation of Intel-based processors based on the combination of high-powered Pentium processor technology and Intel MMX TM media enhancement technology. Benefit from Intel’s MMX technology, make the software more high performance, application performance has room for development. High-powered Pentium ~ * Dynamic execution of the processor technology: * Multi-branch prediction: predict the flow of programs through several branches to speed up the processor’s workflow. Data Flow Analysis: An optimized reordering instruction plan is made by analyzing the data dependencies between instructions. · Speculative Execution: Execute instructions speculatively, based on this optimized arrangement to keep the processor’s superscalar execution unit always running, thereby improving overall performance
