Assembly language continues to hold a core position in the programming world because of its similar structure to machine language and its very close links to underlying computer-processor architecture and design. These features allow for high processing speed, low memory demands, and the capacity to act directly on the system's hardware.
This completely revised second edition of the highly successful Introduction to Assembly Language Programming introduces readers to assembly language programming and its role in computer programming and design. It focuses on providing a firm grasp of the main features of assembly programming, and how it can be used to improve a computer's performance. The revised edition covers a broad scope of subjects and adds valuable material on protected-mode Pentium programming, MIPS assembly language programming, and use of the NASM and SPIM assemblers for a Linux orientation. All of the language's main features are covered in depth. The bookrequires only some basic experience with a structured, high-level language.
Topics and Features:
*Introduces assembly language so that readers can benefit from learning its utility with both CISC and RISC processors [ NEW ]
*Employs the freely available NASM assembler, which works with both Microsoft Windows and Linux operating systems [ NEW ]
*Contains a revised chapter on "Basic Computer Organization" [ NEW]
*Uses numerous examples, hands-on exercises, programming code analyses and challenges, and chapter summaries
*Incorporates full new chapters on recursion, protected-mode interrupt processing, and floating-point instructions [ NEW ]
*Supplies up-to-date details, examples, and software via the author's website
*Provides excellent appendixes and a comprehensive index
Assembly language programming is part of several undergraduate curricula in computer science, computer engineering, and electrical engineering. In addition, this newly revised text/reference can be used as an ideal companion resource in a computer organization course or as a resource for professional courses or self-study.
The Pentium Processor (p. 47)
Objectives
To describe the basic organization of the Pentium processor
To introduce the Pentium protected-mode memory architecture
To discuss the real-mode memory organization
We discussed processor design space in the last chapter. Now we look at the Pentium processor details. We present details of its registers and memory architecture. Other Pentium details are discussed in later chapters.
We start our discussion with a brief history of the Intel architecture. This architecture encompasses the X86 family of processors. All these processors, including the Pentium, belong to the CISC category. Section 3.2 presents the internal register details of the Pentium processor. Even though the Pentium is a 32-bit processor, it maintains backward compatibility to the earlier 16-bit processors. The next two sections describe the protected- and real-mode memory architectures. Protected-mode architecture is the native mode for the Pentium processor. The real mode is provided to mimic the 16-bit 8086 memory architecture. In both modes, the Pentium supports segmented memory architecture. In the protected mode, it also supports paging to facilitate implementation of virtual memory. It is important for an assembly language programmer to understand the segmented memory organization supported by the Pentium. We conclude the chapter with a summary.
3.1 The Pentium Processor Family
Intel introduced microprocessors way back in 1969. Their first 4-bit microprocessor was the 4004. This was followed by the 8080 and 8085 microprocessors. The work on these early microprocessors led to the development of the Intel architecture (IA). The first processor in the IA family was the 8086 processor, introduced in 1979. It has a 20-bit address bus and a 16-bit data bus.
The 8088 is a less expensive version of the 8086 processor. The cost reduction is obtained by using an
These processors can address up to four segments of 64 KB each. This IA segmentation is referred to as the real-mode segmentation and is discussed later in this chapter. The 80186 is a faster version of the 8086. It also has a 20-bit address bus and 16-bit data bus, but has an improved instruction set. The 80186 was never widely used in computer systems. The real successor to the 8086 is the 80286, which was introduced in 1982. It has a 24-bit address bus, which implies 16 MB of memory address space. The data bus is still 16 bits wide, but the 80286 has some memory protection capabilities.
It introduced the protection mode into the IA architecture. Segmentation in this new mode is different from the real-mode segmentation. We present details on this new segmentation later. The 80286 is backward compatible in that it can run the 8086-based software.
Intel introduced its first 32-bit processor - the 80386 - in 1985. It has a 32-bit data bus and 32-bit address bus. The memory address space has grown substantially (from 16 MB address space to 4 GB). This processor introduced paging into the IA architecture. It also allowed de.nition of segments as large as 4 GB. This effectively allowed for a ".at" model (i.e., effectively turning off segmentation). Later sections present details on this. Like the 80286, it can run all the programs written for 8086 and 8088 processors.
