Preliminary Information
AMD-K6™-2E Processor Data Sheet
About this Data Sheet
The AMD-K6™-2E Processor Data Sheet is the complete specification of the
AMD-K6-2E embedded processor.
Overview
This data sheet is organized into the following sections:
Chapter 1, “AMD-K6™-2E Processor” on page 1, provides a list of the AMD-K6-2E
processor’s distinguishing characteristics, a description of the key features, and a
discussion about the Super7™ platform initiative.
Chapter 2, “Internal Architecture” on page 7, describes the functional elements of the
advanced design techniques, known as the RISC86^® microarchitecture, implemented
by the AMD-K6-2E processor.
Chapter 3, “Software Environment” on page 23, 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 processor’s architecture and design implementation.
Chapter 4, “Logic Symbol Diagram” on page 83, contains the AMD-K6-2E processor
logic symbol diagram.
Chapter 5, “Signal Descriptions” on page 85, lists the signals and their descriptions
alphabetically and by function.
Chapter 6, “Bus Cycles” on page 133, describes and illustrates the timing and
relationship of bus signals during various types of bus cycles.
Chapter 7, “Power-On Configuration and Initialization” on page 179, describes how
the system logic resets the AMD-K6-2E processor using the RESET signal.
Chapter 8, “Cache Organization” on page 185, describes the basic architecture and
resources of the AMD-K6-2E processor’s internal caches.
Chapter 9, “Write Merge Buffer” on page 205, describes the 8-byte write merge buffer
and how merging multiple write cycles into a single write cycle ultimately increases
overall system performance.
Chapter 10, “Floating-Point and Multimedia Execution Units” on page 213, describes
the AMD-K6-2E processor’s IEEE 754-compatible and 854-compatible floating point
