1. 2024 Latest Course Renewal

We've added the following courses after discovering beneficial content featuring the latest Arm architecture capabilities that can be directly applied to real-world projects. (3 hours 30 minutes added)

• TRACE32 Program Debugging Content: You can download the educational TRACE32 simulator program from 'Inflearn lecture materials'. You can directly use the TRACE32 simulator program to follow along with the debugging process (including assembly instructions) explained in the lecture and debug it yourself.

• Debugging Practice Lecture: Armv7-A Exception (35 minutes), Armv8-A Exception (2 hours), AAPCS (60 minutes)

• Memory Dump: 3 cases provided for exception debugging

We plan to continuously discover content that helps our students and update the curriculum accordingly.

2. Complete Arm Architecture Author's Direct Lecture Roadmap

This lecture is a roadmap'Arm for System Software Developers - basic course'is included in the course.

For those who want to learn Arm architecture (Armv8-A, Armv7-A) systematically, it would be good to utilize the roadmap (30% discount on all courses). For reference, the Arm architecture roadmap (complete author-taught courses) isBasic Course andAdvanced CourseIt consists of 2 components.

In the latest system software
The most important Arm architecture

Not only smartphones but also AI SoC system semiconductors, electric vehicle Automotive (autonomous driving, infotainment), and Arm processors used in cloud servers and MacBooks are all Armv8-A based 64-bit Cortex-A processors (Cortex-A53, Cortex-A57, Cortex-A72, etc...). Currently, the content that requires the most foundational knowledge needed in the system software industry can be considered the Armv8-A architecture.

However, did the latest Arm architectures, Armv8-A and Armv7-A, feel too difficult to you?

System software developers and embedded system (BSP) programmers, pay attention! 🙋‍♂

Many aspiring Linux embedded developers study computer architecture and operating systems. They also study CS theory to some extent. Developers of system semiconductor and electric vehicle system software, which are emerging recently, analyze Linux device drivers, RTOS, or bootloaders. However, they feel that this alone is somehow insufficient. They know that understanding Arm architecture is essential to become a professional system software developer, but the moment they open the Arm specification documents, they realize it's not an easy path and self-study would be difficult.

We'll explain the core of Arm architecture
in an easy-to-understand way!

It's no exaggeration to say that the core of system software development is CPU and computer architecture. We've made it easy to understand the core theories of the latest Arm architecture (Armv8-A, Armv7-A), which are the CPU processors most needed in the IT industry!

The reason Arm architecture is difficult is because Arm architecture is only learned from a hardware processor perspective. This course explains how the components that make up Arm architecture are actually used through code analysis and concrete case studies. This course will play a pivotal role in helping you become a skilled system software developer.

Course Content 📕

This introduces what exceptions are in CPU architecture and explains the basic operation of exceptions while reviewing the Arm specification.

This explains in detail why you need to understand Arm architecture exceptions in real-world projects.

Explains the exception execution flow of the Armv7 architecture step by step and analyzes in detail the method of handling exceptions through software.

Detailed explanation of how memory aborts - Prefetch or Data Abort - are handled in the Armv7 architecture. Explains the execution flow for processing IRQ interrupt exceptions.

This explains the execution flow of the supervisor call (software interrupt) exception triggered when executing the SVC instruction in the Armv7 architecture. It summarizes the complete execution flow of the exception.

This explains in detail the big picture of how actual Data Abort and Undefined Instruction exceptions are triggered.

This introduces the characteristics of exceptions defined in the Armv8 architecture. It explains the types and classification system of Armv8 architecture exceptions.

Explains the flow of how Synchronous exceptions are handled in the Armv8 architecture.

This explains the execution flow of interrupt handling at each stage in the Armv8 architecture from a big picture perspective. It describes the registers that are updated during this process and the exception handlers.

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

Explains the overall structure of GIC from a big picture perspective and describes the major features of each GIC version.

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

Explains the GIC programmer model designed from a software development perspective and describes the physical structure of the GIC.

This explains the structure of the distributor and the system registers used to control the distributor. It explains 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 provides detailed explanations of their execution flow.

This explains the GIC handler routine (Linux kernel, XEN hypervisor) that controls the GIC through software.

Introducing the main features that make up function calling conventions and AAPCS in CPU architecture.

Armv7-A Architecture: Detailed explanation of the operation methods of PUSH and POP instructions, which are core components of AAPCS.

Armv7-A Architecture: Detailed explanation of the execution flow of the BL instruction, which is core to AAPCS, and related assembly instructions.

Armv8-A Architecture: Detailed explanation of the operation of the STP instruction, which is core to AAPCS, and the operation of BL assembly.

Armv8-A: Introduces methods for solving problems in real-world projects by utilizing knowledge related to AAPCS. Provides detailed explanations of skills that can prevent stack overflow and stack corruption.

The shortcut to understanding Arm's principles is
to directly read and understand the specification documents!

For beginners, Arm is never easy. No matter how beneficial the content is, it's difficult to understand. This course was designed to pave the way for easier access to the challenging Arm architecture theory.

Based on book writing/teaching experience
Deeper and more detailed than anyone else!

In the domestic system software field, this is an unprecedented! author who wrote books on 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel' (both books were selected as excellent books by the Korean Academy), and is a global author who was the first in Korea to write the book "Reverse Engineering Armv8-A Systems" (in English) through an overseas publisher (Packt). Above all, they are a current industry developer who best understands the latest system software trends (electric vehicles, system semiconductors - system software). They are also an educator who is most actively engaged in knowledge dissemination activities in the system software field.

• 'Reverse Engineering Armv8-A Systems: A practical guide to Kernel, Firmware, and TrustZone analysis' book (English) author, (Packt Publishing) - 2025

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

• 'Learning Linux Kernel Structure and Principles Through Debugging' (2021 Korea Academy Outstanding Book Award) Author

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

• June 2022, Korea Computer Congress (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 an educator who can explain the key features that make up the Arm architecture (Armv8-A, Armv7-A) better than anyone else in Korea.
