There are three main reasons for writing this book. While several assembly language books are on the market, almost all of them cover only the 8086 processor-a 16-bit processor Intel introduced in 1979. A modem computer organization or assembly language course requires treatment of a more recent processor like the Pentium, which is a 32-bit processor in the Intel family. This is one of the main motivations for writing this book. There are two other equally valid reasons. The book approaches assembly language programming from the high-level language viewpoint. As a result, it focuses on the assembly language features that are required to efficiently implement high-level language constructs. Performance is another reason why people program in assembly language. This is particularly true with real-time application programming. Our treatment of assembly language programming is oriented toward performance optimiza­ tion. Every chapter ends with a performance section that discusses the impact of specific sets of assembly language statements on the performance of the whole program. Put another way, this book focuses on performance-oriented assembly language programming. Intended Use This book is intended as an introduction to assembly language programming using the Intel 80X86 family of processors. We have selected the assembly language of the Intel 80X86 processors (including the Pentium processor) be­ cause of the widespread availability of PCs and assemblers. Both Microsoft and Borland provide assemblers for the PCs.

A crystal-clear and practical blueprint to software disassembly

The long-awaited x64 edition of the bestselling introduction to Intel assembly language

The vast majority of computers in use today are encapsulated within other systems. In contrast to general-purpose computers that run an endless selection of software, these embedded computers are often programmed for a very specific, low-level and often mundane purpose. Low-end microcontrollers, costing as little as one dollar, are often employed by engineers in designs that utilize only a small fraction of the processing capability of the device because it is either more cost-effective than selecting an application-specific part or because programmability offers custom functionality not otherwise available. Embedded Systems Interfacing for Engineers using the Freescale HCS08 Microcontroller is a two-part book intended to provide an introduction to hardware and software interfacing for engineers.

This hands-on tutorial is a broad examination of how a modern computer works. Classroom tested for over a decade, it gives readers a firm understanding of how computers do what they do, covering essentials like data storage, logic gates and transistors, data types, the CPU, assembly, and machine code.
