Chapter One:
System Organization
A gentle introduction to the components that make up a
typical PC.
Chapter Two:
Memory Access and Organization
A discussion of the 80x86 memory addressing modes
and how HLA organizes your data in memory.
Chapter Three: Introduction to Digital Design
A low-level description of how computer designers
build CPUs and other system components.
Chapter Four:
CPU Architecture
A look at the internal operation of the CPU.
Chapter Five:
Instruction Set Architecture
This chapter describes how Intel’s engineers designed
the 80x86 instruction set. It also explains many of their
design decisions, good and bad.
Chapter Six:
Memory Architecture
How memory is organized for high performance com-
puting systems.
Chapter Seven: The I/O Subsystem
Input and output are two of the most important functions
on a PC. This chapter describes how input and output
occurs on a typical 80x86 system.
