SYSTEM ARCHITECTURE OVERVIEW
2.1 OVERVIEW OF THE SYSTEM-LEVEL ARCHITECTURE
IA-32 system-level architecture consists of a set of registers, data structures, and instructions
designed to support basic system-level operations such as memory management, interrupt and
exception handling, task management, and control of multiple processors.
Figure 2-1 provides a summary of system registers and data structures that applies to 32-bit
modes. System registers and data structures that apply to IA-32e mode are shown in Figure 2-2.
