Armv8-A Architecture Overview for New Developers (Direct Lecture by the Author)

<Notice>

Arm Architecture Full Author Direct Lecture Roadmap

This lecture <Armv8-A Architecture for New Developers (Author Direct 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.

System software developer
Essential Knowledge, Arm Architecture

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

Finished in 9 hours
Introduction to the Core Armv8-A Architecture

I have written a book explaining the Armv8-A architecture and have also produced over 60 hours of lectures for Inflearn.

• Structure and Principles of Arm Architecture for System Software Development - Part 1 Author's Lecture (22 hours)

• Structure and Principles of Arm Architecture for System Software Development - Part 2 Author Lecture (20 hours)

• Roadmap: Arm for System Software Developers - Advanced Course (21 hours)

  
  

However, it takes more than 3 months for someone who is learning Arm architecture for the first time to digest a lecture of more than 60 hours. Of course, the best way is to take the lectures step by step and learn Arm architecture systematically. However, in reality, job seekers and junior developers often have to prepare for technical interviews within 1-2 weeks . Reflecting the needs of these students, we launched a compact but essential introduction to the Armv8-A architecture .

Learn about these things 📕

This course introduces the Arm processor while explaining the process of developing system semiconductors. It also introduces the basic functions that make up the Armv8-A architecture.

Describes the structure of registers and provides various examples of how registers are used.

Describes special registers and covers the execution flow in which they are modified.

We introduce the boot process and explain how assembly instructions are used in real-world projects. We then analyze the basic format and command routines of assembly instructions.

It analyzes assembly instructions in detail in various ways and explains the syntax of the instructions in an easy-to-understand manner.

Debug assembly instructions using TRACE32, a practical debugging program. Analyze assembly instructions and learn in detail how registers are used.

Explains the concepts of exception level and privilege level in an easy-to-understand manner.

Explains how software executes at different exception levels with various examples.

This section details how the exception level is set during booting. It explains how to check the exception level using assembly instructions.

It details the exception vector table and the execution flow through which exceptions are handled.

Interrupts are handled as a type of exception in the Armv8-A architecture. Here is a simple explanation of how IRQ interrupt exceptions are handled through various execution flows.

Describes the process by which an exception is triggered during the execution of a system call. It also describes the execution flow of an exception along with the exception vector table.

TRACE32 debugging practice details how the Arm core branches to the exception vector address when an exception is triggered.

Describes the basic core concepts and execution flow for AAPCS, which specifies how to branch to subroutines such as functions.

We'll explain how the stack is used from a software perspective and provide optimizations that can be applied directly to real-world projects.

An easy-to-understand explanation of the core concepts (non-secure world, secure world) and execution flow of TrustZone.

This explains the operating principle of Secure monitor call with TRACE32 debugging practice. It explains in detail the operation of entering EL3 when executing SMC instruction in EL1 and also analyzes in detail the operation method of exception caused in this process.

This explains the structure and virtualization functions of hypervisors, which are widely used in electric vehicle (Automotive) development.

This explains the process of entering the hypervisor from the guest OS through the hypervisor call, which is the core of the virtualization technique. It also explains the execution flow of receiving and processing an exception from the hypervisor.

This tutorial explains in detail how to enter EL2 (hypervisor) by executing HVC instructions in EL1 (guest OS) using TRACE32 debugging practice. It also explains in simple terms how exceptions that occur during this process work.

Explains the basic concepts of cache and provides an easy-to-understand explanation of the basic structure and policies of multi-level cache.

An easy-to-understand explanation of the memory model and memory barriers.

Describes the components that make up the virtual memory system and the execution flow through which virtual addresses are processed.

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 (1st and 2nd sessions)

• 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 Armv8-A architecture better than anyone else in Korea.
