Arithmetic Blocks
Arithmetic circuits are an essential part of many digital circuits and thus deserve a particular treatment. In this chapter implementations of the basic arithmetic operations are presented. Only operations with naturals (nonnegative integers) are consider

Preface
Digital electronic components are present in almost all our private and professional activities: • Our personal computers, our smartphones, or our tablets are made up of digital components such as microprocessors, memories, interface circuits, and so on. • Digital components are also present within our cars, our TV sets, or even in our household appliances. • They are essential components of practically any industrial production line. • They are also essential components of public transport systems, of secure access control systems, and many others. We could say that any activity involving: • The acquisition of data from human interfaces or from different types of sensors • The storage of data • The transmission of data • The processing of data • The use of data to control human interfaces or to control different types of actuators (e.g., mechanical actuators), can be performed in a safe and fast way by means of Digital Systems. Thus, nowadays digital systems constitute a basic technical discipline, essential to any engineer. That’s the reason why the Engineering School of the Autonomous University of Barcelona (UAB) has designed an introdu
