  15 <H1>Chapter 4  Systems Architecture</H1>
  16 <P>
  17 Many of the architectural features of the 80386 are used only by systems
  18 programmers. This chapter presents an overview of these aspects of the
  19 architecture.
  20 <P>
  21 The systems-level features of the 80386 architecture include:
  22 <UL>
  23 <LI>Memory Management
  24 <LI>Protection
  25 <LI>Multitasking
  26 <LI>Input/Output
  27 <LI>Exceptions and Interrupts
  28 <LI>Initialization
  29 <LI>Coprocessing and Multiprocessing
  30 <LI>Debugging
  31 </UL>
  32 These features are implemented by registers and instructions, all of which
  33 are introduced in the following sections. The purpose of this chapter is not
  34 to explain each feature in detail, but rather to place the remaining
  35 chapters of Part II in perspective. Each mention in this chapter of a
  36 register or instruction is either accompanied by an explanation or a
  37 reference to a following chapter where detailed information can be obtained.
