2. Arm Architecture Full Author Direct Lecture Roadmap

This lecture <Structure and Principles of Arm Architecture for System Software Development - Part 2 Author's Lecture> is a roadmap 'Arm - basic course for system software developers' This lecture is included in .

If you want to learn Arm architecture (Armv8-A, Armv7-A) systematically , it is recommended to use the roadmap (30% discount on all lectures). For reference, the Arm architecture roadmap (all author lectures) is Basic Course and Advanced Course It consists of two parts.

In the latest system software
The most important Arm architecture

The Arm processors used in smartphones, AI SoC system semiconductors, electric vehicles (autonomous driving, infotainment), cloud servers, and MacBooks are all Armv8-A based 64-bit Cortex-A processors (Cortex-A53, Cortex-A57, Cortex-A72, etc.). The Armv8-A architecture can be seen as the most needed basic knowledge in the current system software industry.

But, did you find the latest Arm architectures, Armv8-A and Armv7-A, too difficult ?

Attention System Software Developers, Embedded System (BSP) Programmers! 🙋‍♂

Many Linux embedded developers learn computer architecture and operating systems. They also study CS theory to some extent. Recently, rising system semiconductor and electric vehicle system software developers analyze Linux device drivers, RTOS, or bootloaders. However, they feel that something is lacking . They know that they must know the Arm architecture to become a professional system software developer, but when they actually open the Arm specification document, they decide that it is not an easy path and that self-study is difficult.

The core of the Arm architecture
Let me explain it to you in an easy-to-understand way!

It is no exaggeration to say that the core of system software development is CPU and computer architecture. We have easily explained the core theory of the latest Arm architecture (Armv8-A, Armv7-A) , the most needed CPU processor in the IT industry!

The reason why Arm architecture is difficult is because it is learned only from the perspective of the hardware processor. This lecture explains how the contents of the Arm architecture are actually used through code analysis and specific case introduction. This lecture will play a pivotal role in helping you become a capable system software developer.

Lecture Content 📕

Introduces what exceptions are in CPU architectures and explains the basic behavior of exceptions while reviewing the Arm specification.

Explains in detail why you need to know exceptions in the Arm architecture for real-world projects.

We will explain the exception execution flow of the Armv7 architecture step by step and analyze in detail how exceptions are handled by software.

Describes in detail how Memory Abort - Prefetch or Data Abort is handled in the Armv7 architecture. Describes the execution flow for handling IRQ interrupt exceptions.

Describes the execution flow of a supervisor call (software interrupt) exception that occurs when executing an SVC instruction on the Armv7 architecture. Summarizes the entire execution flow of the exception.

It provides a detailed, big picture explanation of the behavior that actually causes Data Abort and Undefined Instruction exceptions.

Introduces the characteristics of exceptions defined in the Armv8 architecture. Describes the types and classification system of exceptions in the Armv8 architecture.

Describes the flow of handling Synchronous exceptions in the Armv8 architecture.

Provides a high-level overview of the execution flow for each stage of interrupt processing in the Armv8 architecture. It describes the registers and exception handlers that are updated during this process.

Introduces the interrupt controller and explains the overall structure of the GIC.

It provides a big picture explanation of the overall structure of GIC and explains the main functions of each version of GIC.

Describes the interrupt sources and types defined in GIC and explains how interrupts are handled in SMP (multi-core systems).

We describe the programmer model of GIC designed from a software development perspective and explain the physical structure of GIC.

Describes the structure of the distributor and the system registers used to control the distributor. Describes the structure of the CPU interface and the system registers used to control the CPU interface.

Explains the core concepts of IRQ and FIQ and explains the execution flow in detail.

Describes the GIC handler routines (Linux kernel, XEN hypervisor) that control the GIC through software.

Introduces the function calling conventions and key features that make up the AAPCS in CPU architectures.

Armv7-A Architecture: Describes in detail how the PUSH and POP instructions, which are the core of AAPCS, work.

Armv7-A Architecture: Describes in detail the execution flow of the BL instruction, which is the core of AAPCS, and related assembly instructions.

Armv8-A Architecture: Explains in detail how the STP instruction, which is the core of AAPCS, works and how BL assembly works.

Armv8-A: How to use your knowledge of AAPCS to solve problems in real-world projects. Detailed description of skills to prevent stack overflow and stack pollution.

A shortcut to understanding the principles of Arm is
Read and understand the spec document yourself!

For beginners, Arm is never easy. No matter how useful the content is, it is difficult to understand. This course is designed to open the way for you to approach the difficult Arm architecture theory more easily.

Based on my experience writing books and giving lectures
More in-depth and detailed than anyone else!

Unparalleled in the domestic system software field! Author of 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel' ( both books selected as excellent books by the Korean Academy of Sciences ) and global author who wrote the book "Reverse Engineering Armv8-A Systems" (English) through a foreign publisher (Packt) for the first time in Korea . Above all, he is a working developer who knows the latest system software trends (electric vehicles, system semiconductors - system software) the best. He is also an educator who is most active in knowledge dissemination in the field of system software.

• Author of the book 'Reverse Engineering Armv8-A Systems: A practical guide to Kernel, Firmware, and TrustZone analysis' (Packt Publishers) - 2025

• Author of 'Structure and Principles of Arm Architecture for System Software Development' ( 2024, Korean Academy of Sciences Outstanding Book Award )

• Author of 'Learning the Structure and Principles of the Linux Kernel through Debugging' ( 2021, Korean Academy of Sciences Outstanding Book Award )

• 'Programmers Dev Course: Linux System and Kernel Expert' Main Instructor

• June 2022, Korea Computer Conference (KCC2022) - Tutorial presentation [Conquering the Linux Kernel using ftrace]

• LG Electronics 'Linux Kernel' and 'Armv8 Architecture' In-house Instructor ( including domestic and overseas developers ) - (2020~2024)

I can confidently say that I am the educator who can explain the key features of the Arm architecture (Armv8-A, Armv7-A) better than anyone else in Korea.
