All high-level languages are ultimately translated into machine instructions that control a computer's hardware. Introduction to Computer Organization: ARM reveals exactly how that hardware works 'under the hood.' Written for anyone familiar with basic programming concepts, the reader is taken through the machine's architecture from the bottom up and the software on down - with a special focus on the ARM instruction set commonly found in smartphones, laptops, and tablets. Beginning with an exploration of modern computing's mathematical foundations - including the binary system and Boolean algebra - the book introduces hardware components such as circuits, CPU, and memory. Later chapters discuss how software controls hardware, providing an in-depth look at the basic programming constructs in low-level languages like C and C++. Finally, readers are shown how the computer's compiler translates code into assembly language that can directly access the instruction set architecture.
