Overview of this book

ARM embedded assembly programming supports many of the devices that you use daily and if you want to go a step ahead and explore how to write flawless programs, develop algorithms, and build machines in assembly, here's something you need to consider. Before you write error-free assembly programs for a processor, understanding the architecture of the processor is crucial. This video course will guide you through ARM architecture and help you develop flawless algorithms and machines in ARM assembly. The course begins with an introduction to the ARM assembly language, enabling you to understand assembly tools and syntax. Next, you'll become familiar with the ARM design philosophy and RISC architecture and gain a detailed understanding of the ARM instruction set, the Thumb instruction set, and the Thumb-2 instruction set. Moving ahead, you'll create data structures such as FIFOs and LIFOs and design complex algorithms for performing binary search in assembly. You'll also solve advanced mathematical problems such as the Taylor series and the Bisection algorithm. Toward the end, you'll develop Finite state machines such as the Moore and Mealy machines and get an overview of Keil uVision 5 - the software development solution for ARM-based controllers. By the end of this course, you'll have developed the skills you need to start your career as an ARM embedded developer. The code bundle for this course is available at https://github.com/PacktPublishing/ARM-Assembly-Language-from-Ground-Up-1
