Introduction to ARM Processors: Modern Processor Features and Cortex-A9 Microarchitecture Analysis
Previous Articles:Introduction to ARM Processors 1 - OverviewIntroductionThis article is the second part of the introduction series on ARM processors, mainly introducing some basic technologies and concepts of modern superscalar out-of-order processors. We will take the Cortex-A9 processor as an example to see which technologies are used to enhance performance, laying the foundation for our subsequent understanding of the microarchitecture of ARM processors and comparative analysis.Note: In fact, explaining the key points of modern processor technology can be quite complicated. Each technology might require an article, and since I am not from a related professional background, my energy and understanding depth are limited. Therefore, I can only roughly list some basic concepts. For more in-depth analysis, you can refer to
