AMD-K6™-2E Processor Microarchitecture Overview
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 superior sixth-generation
performance for x86-based software. This chapter describes the
techniques used and the functional elements of the RISC86
microarchitecture.
When discussing processor design, it is important to understand
t h e t e r m s a r ch i t e c t u re , m i c r o a r ch i t e c t u re , a nd d e s 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.
