Introduction

This 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.
