Computer Arithmetic in Practice: Exercises and Programming is a simple, brief introductory volume for undergraduate and graduate students at university courses interested in understanding the foundation of computers. It is focused on numeric data formats and capabilities of computers to perform basic arithmetic operations. It discusses mainly such topics as:
Basic concepts of computer architecture
Assembly language programming skills
Data formats used to express integer and real numbers
Algorithms of basic arithmetic operations
Short overview of nonlinear functions evaluation
Discussion on limited number representation and computer arithmetic
Exercises and programming tasks
This book provides an accessible overview of common data formats used to write numbers in programming languages and how the computer performs four basic arithmetic operations from the point of view of the processor instruction set. The book is primarily didactic in nature, therefore the theoretical information is enriched with many numerical examples and exercises to be solved using a ‘sheet of paper and a pencil’. Answers are provided for most of the tasks.
To prepare and run program, we need some tools like: assembler, linker (optionally) and loader. The assembly language is a low-level programming language but assembler is a software responsible just for translating source code directly to the machine code or sometimes indirectly to the object code aimed to reuse in another program. A linker is a program merging one or more files generated earlier by a compiler or an assembler and combines them into a single executable file, library file or another ‘object’ file. Typically, one or more commonly used libraries are usually linked in by default. The linker also takes care of arranging the objects in a program’s address space.
The theoretical discussed issues are illustrated by listings of algorithms presenting the way to implement arithmetic operations in low-level language. It allows development of the skills of optimal programming, taking into consideration the computer architecture and limitations. Creating software using low-level language programming, despite the initial difficulties, gives the ability to control the code and create efficient applications. This allows for effective consolidation of knowledge and acquisition of practical skills required at this stage of education, mainly a specialist in the field of information technology, electronics, telecommunications, other related disciplines, or at the level of general education with introduction to information technology. It may be also useful for engineers interested in their own professional development and teachers as well.
