This chapter introduces the MOV, ADD, and SUB instructions, first by gradually providing a foundation for understanding the functionality of the commands, particularly in how parameters (operands) are handled. In subsequent chapters, the rest of the ARM instruction set is covered at a faster pace. Before delving into the specifics of MOV, ADD, and SUB instructions, topics such as the representation of negative numbers, as well as the concepts of shifting and rotating bits, will be addressed.

摘要

This chapter introduces the MOV, ADD, and SUB instructions, first by gradually providing a foundation for understanding the functionality of the commands, particularly in how parameters (operands) are handled. In subsequent chapters, the rest of the ARM instruction set is covered at a faster pace. Before delving into the specifics of MOV, ADD, and SUB instructions, topics such as the representation of negative numbers, as well as the concepts of shifting and rotating bits, will be addressed.
