Preliminary Information

Internal Architecture

The AMD-K6-2E processor implements advanced design

techniques known as the RISC86 microarchitecture. The

RISC86 microarchitecture is a decoupled decode/execution

design approach that yields superi or sixth-generatio n

performance for x86-based software. This chapter describes the

techniques used and the functional elements of the RISC86

microarchitecture.

AMD-K6™-2E Processor Microarchitecture Overview

When discussing processor design, it is important to understand

the term s architectur e , m i croar chitectur e , an d des i g n

implementation.

Architecture refers to the instruction set and features of a

processor that are visible to software programs running on

the processor. The architecture determines which software

the processor can run. The architecture of the AMD-K6-2E

processor is the industry-standard x86 instruction set.

Microarchitecture refers to the design techniques used in the

processor to reach the target cost, performance, and

functionality goals. The AMD-K6-2E processor is based on a

sophisticated RISC core known as the Enhanced RISC86

microarchitecture. The Enhanced RISC86 microarchitecture

is an advanced, second-order decoupled decode/execution

design approach that enables industry-leading performance

for x86-based software.

Design implementation refers to the actual logic and circuit

designs from which the processor is created according to the

microarchitecture specifications.
