2. Roadmap Guide 🎯

This lectureRoad Map'Arm for System Software Developers - Advanced 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 (all courses taught directly by the author) isBasic Course andAdvanced CourseIt consists of 2 parts.

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 fundamental knowledge needed in the system software industry can be considered the Armv8-A architecture.

The first step to becoming an advanced system SW developer!
Understanding memory management methods 🙋‍♂

However, to become an advanced system software developer, you need to have a good understanding of how memory is managed among the key features that make up the Arm architecture. The core of memory management consists of 'Memory Management Unit (MMU)', 'cache operation principles', and 'memory model and barriers'.
Among these, one of the most important features that system software developers need to know is the 'Memory Management Unit (MMU)' related to virtual memory systems.

'Memory Management (MMU)' - Why should we learn it?

1⃣ First, when bringing up systems based on RTOS or Linux kernel or developing device drivers, you cannot proceed with development properly without a good understanding of virtual memory concepts. When bringing up a board, situations may arise where you need to set the attributes or permissions of virtual addresses, and the concepts of virtual memory and MMU are necessary for this.

2⃣ Second, the foundational knowledge for understanding memory abort, page fault, and demand paging operation mechanisms is virtual memory and MMU. Without a proper understanding of how virtual addresses are managed in pages, you cannot properly grasp these operational principles.

3⃣ Third, virtual memory and MMU are foundational knowledge that allows you to understand the detailed operational principles inside Arm processors.

4⃣ Fourth, to perform well in technical interviews related to system software development, you must have a good understanding of 'the concepts of virtual memory and MMU'. One of the frequently asked questions in experienced developer interviews is content related to 'virtual memory and MMU'.

Since most system software developed recently runs in virtual memory system environments, knowledge related to this is essential.

The know-how of system SW developers
presented in an easy and detailed way!

This course is a direct lecture by the author of 'Structure and Principles of Arm Architecture for System Software Development', covering in detail the Memory Management Unit (MMU) of Arm architecture (Armv8-A), which is the core of memory systems.
This lecture took the most time to produce among all the author's direct lectures I have created so far.

⭐️ Course Differentiation Points ⭐️

If you digest this course well, you can grow into an advanced system software developer. I support you in upgrading your career to higher salaries and positions.

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

In the domestic system software field, I am the unprecedented author who wrote books on 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel'. I am also a current industry developer who has the best understanding of the latest system software trends (electric vehicles, system semiconductors - system software), and an educator who is most actively engaged in knowledge dissemination activities in the system software field.

• 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

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

• 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.
