The architecture of the AMD-K6-2 processor is the industry-standard x86 instruction set.
The term microarchitecture refers to the design techniques used in the processor to reach the target cost, performance, and functionality goals. The AMD-K6 family of processors are 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.
The term design implementation refers to the actual logic and circuit designs from which the processor is created according to the microarchitecture specifications.
