2. Roadmap Guide 🎯

This lecture is a roadmap 'Arm - advanced 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.

The first step to becoming an advanced system SW developer!
Understanding Memory Management 🙋‍♂

However, in order to become an advanced system software developer, you must have a good understanding of how to manage memory, which is one of the main functions that make up the Arm architecture. The core of how to manage memory is ' Memory Management (MMU) ', 'Cache Operation Principles', and ' Memory Model and Barrier ' .
One of the most important features that a system software developer should know is the 'Memory Management Unit (MMU)' related to the virtual memory system .

Why should we learn ' Memory Management Unit (MMU) '?

1⃣ First, when bringing up or developing a device driver in an RTOS or Linux kernel-based system, you cannot properly proceed with development if you do not understand the concept of virtual memory. When bringing up a board, there may be a situation where you need to set the properties or permissions of a virtual address, and the concepts needed for this are the concepts of virtual memory and MMU.

2⃣ Second, the basic knowledge that can help you understand memory aborts, page faults, and how dimension paging works is virtual memory and MMU. If you don’t know how to manage virtual addresses as pages, you won’t be able to properly understand these operating principles.

3⃣ Third, virtual memory and MMU are basic knowledge that can help you understand the operating principles inside the Arm processor in detail.

4⃣ Fourth, in order to do well in a technical interview related to system software development, you need to understand the concept of ‘virtual memory and MMU’. One of the questions that comes up frequently in interviews for experienced developers is related to ‘virtual memory and MMU’.

Most system software developed recently runs in a virtual memory system environment, so knowledge related to this is essential.

Know-how of system SW developers
It's easy and detailed!

This lecture is a direct lecture by the author of 'Structure and Principles of Arm Architecture for System Software Development' , and covers in detail the memory management (MMU) of the Arm architecture (Armv8-A), which is the core of the memory system.
This lecture took the most time to produce among all the author-directed lectures I have produced so far.

⭐ ️ Differentiating Points of the Lecture ⭐ ️

If you successfully complete this course, you will be able to grow into an advanced system software developer. I hope you will upgrade your career with a higher salary and position.

Learn about these things 📕

Describes in detail the main functions and flow that make up memory management.

Explains how to leverage the content related to memory management from a practical development perspective.

Before explaining the main functions of the MMU, we first need to understand the concept of virtual memory.
Describes in detail the major elements and structures that make up the virtual memory system.

It explains in detail the structure and execution flow of the MMU and the main functions that make up the MMU.

It explains the detailed operation principles of converting virtual addresses to physical addresses and the structure of multi-level pages.

Provides detailed information about the assembly instructions that are executed when setting the range of virtual addresses and the functionality of the MMU.

We will explain in detail the main bit fields that make up the TCR_EL1 register using the TRACE32 debugging program. We will analyze and practice various system registers that can provide information related to faults using the debugging program called crash-utility.

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

The author of the unprecedented 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel' books in the domestic system software field. He is also a working developer who knows the latest system software trends (electric vehicles, system semiconductors - system software) the best, and an educator who is most active in spreading knowledge in the system software field.

• 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.
