AMD-K5 Processor Technical Reference Manual
Preface
This manual describes the technical features of the AMD-K5™ processor, and its dif-
ferences from the Pentium processor, at a level of detail suitable for a hardware
designer or system-software developer to implement system boards, core system
logic, and system software. Specifically, the manual describes the following aspects
of the processor
■
Internal architecture
■
Software differences from the 486 and Pentium processors
■
Performance parameters
■
Bus signals functions
■
Bus cycle timing
■
Design issues for system-board designs
■
Test and debugging features
A full description of the x86 programming environment is beyond the scope of this
manual. Instead, the software sections describe differences from the 486 processor’s
programming environment. A list of commercial books that describe the x86 pro-
gramming environment and other subjects of potential interest appears at the end of
this preface.
In addition to descriptions of the AMD-K5 processor’s unique internal architecture,
the manual incorporates details about the behavior of bus signals and bus cycles that
are standard to the x86 processors but that are not fully documented in other x86
manuals.
