Software Environment
Registers
This chapter provides a general overview of the AMD-K6-2E
processor’s x86 software environment and briefly describes the
data types, registers, operating modes, interrupts, and
instructions supported by the AMD-K6-2E architecture and
design implementation.
The s tepping of the Model 8 versi on of the proces sor
determines the implementation and format of ten Model-
Specific Registers (MSRs).
The AMD-K6-2E processor supports Model 8 steppings [F:8] in
any of eight possible model/steppings—Models 8/8, 8/9, 8/A, 8/B,
8/C, 8/D, 8/E, or 8/F.
Note that the name AMD-K6-2E processor by itself refers to all
steppings of the Model 8/[F:8] version.
The AMD-K6-2E processor contains all the registers defined by
the x86 architecture, including general-purpose, segment,
floating-point, MMX/3DNow!, EFLAGS, control, task, debug,
test, and descriptor/memory-management registers.
In addition to information about these registers, this chapter
provides information on the AMD-K6-2E processor MSRs.
Note: Areas of the register designated as Reserved should not be
modified by software.
