2. Roadmap Guide 🎯

This lecture, <Arm Architecture: Memory Management (MMU) [Author's Lecture Part 3-5]>, is included in the roadmap 'Arm for System Software Developers - advanced course'.

For those who wish to learn the Arm architecture (Armv8-A, Armv7-A) systematically, it is recommended to take advantage of the roadmap (30% discount on all lectures). For your reference, the Arm Architecture Roadmap (full series taught by the author) consists of two parts: Basic Course and Advanced Course.

In modern system software,
the most important Arm architecture

Arm processors used in smartphones, AI SoC system semiconductors, electric vehicle automotive (autonomous driving, infotainment), cloud servers, and MacBooks are all Armv8-A based 64-bit Cortex-A processors (Cortex-A53, Cortex-A57, Cortex-A72, etc.). It can be said that the Armv8-A architecture is the area where foundational knowledge is most in demand in the current system software industry.

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

However, to become an advanced system software developer, you must have a good understanding of how memory is managed, which is one of the key features of the Arm architecture. The core of memory management consists of 'Memory Management (MMU)', 'Cache Principles', and 'Memory Models and Barriers'.
Among these, one of the most important features a system software developer must know is 'Memory Management (MMU) related to virtual memory systems'.

'Memory Management Unit (MMU)', why should we learn it?

1⃣ First, when performing bring-up or developing device drivers in RTOS or Linux kernel-based systems, you cannot proceed with development properly without a solid understanding of virtual memory concepts. Situations may arise where you need to configure virtual address attributes or permissions during board bring-up, and the concepts of virtual memory and MMU are essential for this.

2⃣ Second, virtual memory and MMU are the foundational knowledge required to understand memory aborts, page faults, and demand paging operations. Without a solid understanding of how virtual addresses are managed in pages, it is impossible to properly grasp these operational principles.

3⃣ Third, virtual memory and MMU are foundational knowledge for understanding the internal operating principles of the Arm processor in detail.

4⃣ Fourth, you need to have a good understanding of the 'concepts of virtual memory and MMU' to perform well in technical interviews related to system software development. One of the most common questions in interviews for experienced developers is related to 'virtual memory and the MMU'.

Since most modern system software is executed in a virtual memory system environment, knowledge of this subject is essential.

The know-how of a system SW developer
is captured easily and in detail!

This course is a lecture by the author of 'Arm Architecture: Structure and Principles for System Software Development', and it covers in detail the Memory Management Unit (MMU) of the Arm architecture (Armv8-A), which is the core of the memory system.
This lecture is the one I have invested the most time in among all the author-led lectures I have produced so far.

⭐️ Key Differentiating Points of the Lecture ⭐️

If you master this course, you will be able to grow into a senior system software developer. I support you in upgrading your career with a higher salary and position.

What you will learn 📕

It explains the key functions and flows of memory management in detail.

It explains how to utilize content related to memory management from a practical development perspective.

Before explaining the main functions of the MMU, it is necessary to first understand the concept of virtual memory.
The key elements and structure that make up the virtual memory system are explained in detail.

We explain the structure and execution flow of the MMU, as well as its key components, in detail.
We also explain the detailed operating principles of converting virtual addresses to physical addresses and the structure of multi-level pages.

It explains the detailed operating principles of converting virtual addresses to physical addresses, along with the structure of multi-level pages.

We provide a detailed introduction to the assembly instructions executed when setting the virtual address range and configuring MMU functions.

While using the TRACE32 debugging program, we explain the major bit fields that constitute the TCR_EL1 register in detail. We also analyze and practice with various system registers that provide fault-related information using a debugging program called crash-utility.

Based on my experience writing books and lecturing,
deeper and more detailed than anyone else!

I am the author of the unprecedented books on 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel' in the domestic system software field. I am also an active developer who is well-versed in the latest system software trends (electric vehicles, system semiconductors - system software), and an educator who is most actively engaged in spreading knowledge within the system software field.

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

• 'Structure and Principles of the Linux Kernel Learned Through Debugging' (2021, National Academy of Sciences 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' Internal Instructor (Including domestic and overseas developers) - (2020~2024)

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