The Kunpeng 920 series chip designed by Huawei Hisilicon is a high-performance processor System on Chip (SoC) compatible with the ARMv8-A architecture. It is the core product of the Kunpeng chip family, which is part of Huawei’s five-product series of “computing, storage, transmission, management, and intelligence.” The book first introduces the technical background of high-performance processors and servers and then summarizes the architecture of ARMv8-A processors. On this basis, it focuses on discussing the architecture of Kunpeng 920 SoC, its software ecosystem, and its structure. To help readers understand the application scenarios of the Kunpeng 920 SoC, the book provides installation, configuration, development, and application cases of server software based on the Kunpeng 920 SoC at the end.This book can serve as a reference for readers to understand and apply the Kunpeng 920 SoC. It is especially suitable for software architects and software engineers who are interested in using the Kunpeng 920 SoC, as well as application engineers and optimization engineers who have to develop and optimize applications on the Kunpeng 920 SoC. The book can also be used as a textbook for undergraduate and graduate students in computer science and technology, big data, artificial intelligence, and other related majors in general colleges and universities. Readers interested in computer organization and design can also use this book to learn about the architecture of modern high-performance processors.
