ARM Assembly Language: Fundamentals and Techniques, Third Edition explains in clear terms how ARM processors are programmed at the most fundamental level. While earlier editions covered much older architectures, the Third Edition moves entirely into the Cortex-M space, using the Armv8-M instruction set to illustrate how assembly code for the most modern Arm processors is written. Even if you are writing in JavaScript, Python, C++, C#, or Rust, these high-level programming languages require a compiler or interpreter to transform the code into machine-executable instructions, so software and hardware engineers will gain valuable insight into how their code is executing from knowing how the underlying processor functions. Featuring chapters updated to Armv8-M throughout this book, this edition:Moves all examples into the Keil MDK environment, which uses armclang and a GNU-like syntax that is very popular in the industryIncludes an appendix that helps students set up the Keil tools for use throughout this bookDescribes the IEEE 754 floating-point arithmetic supported by the Armv8-M processors implementing the optional Floating-Point Unit (FPU)Features an updated chapter on mixing C and assembly code togetherDiscusses features and concepts found in the most advanced Arm processors, such as the Cortex-A and Cortex-X families using Armv9 architecturesWritten by authors who each have more than 35 years of experience in the semiconductor industry, ARM Assembly Language: Fundamentals and Techniques, Third Edition makes an ideal textbook for students wanting to learn about microprocessors but who may possess only a basic knowledge of programming and logic.
