Description

Gaining a solid understanding of Assembly instructions, registers, processor modes, and exception levels in Arm(Armv7-A and Armv8-A) architecture. Effectively learn Arm architecture using TRACE32 and gain sufficient insight into the inner workings of Armv7-A, Armv8-A, and Linux kernel internalsWhy should we learn the Arm architecture?Arm processors are used in smartphones, AI-based SoCs (System on Chips), electric vehicles (for autonomous driving and infotainment), as well as in cloud servers and MacBooks. These processors are all based on Armv8-A 64-bit Cortex-A processors (like Cortex-A53, Cortex-A57, Cortex-A72, etc.). In the system software industry today, understanding the Armv8-A architecture is one of the most important and required skills. But do you find Armv8-A and Armv7-A architectures difficult to understand?The challenges of learning the Arm architectureMany people who want to be Linux embedded developers learn computer architecture and operating systems. They also study CS (computer science) theory to some extent. Nowadays, BSP engineers in chipset company and system software engineer in Automotive sector analyze Linux device drivers, RTOS, or bootloaders. But still, something seems to be missing. They know that to become a professional system software developer, they must understand the Arm architecture. Yet, when they open the Arm spec documents, they realize that learning it alone can be very hard.By the end of this course:You will learn the basics of Arm architecture, including registers, assembly instructions, operation modes, and exception levels.You will understand key parts of Arm architecture by analyzing code examples.You will become familiar with practical features of Arm architecture that help you develop stable and high-performance system software, like drivers and bootloaders.You will be able to use TRACE32 to work directly with assembly instructions, applying key concepts to real-world examples.Final message for system software developers!To become a competitive system software engineer, understanding ARM architecture is essential. This course breaks down the difficult and complex features of modern ARM architectures (Armv8-A, Armv7-A) into easy-to-understand content. It explains how the architecture is actually used with real project examples and sample code analysis. This course will be a key step in helping you become a highly skilled system software developer.
