  When discussing processor design, it is important to understand the terms architecture, microarchitecture, and design implementation.

  The architecture consists of the instruction set and those features of a processor that are visible to software programs running on the processor. The architecture determines what software the processor can run. The AMD64 architecture of the AMD Athlon™ 64 and AMD Opteron™ processors is compatible with the industry-standard x86 instruction set.

  The term microarchitecture refers to the design features used to reach the target cost, performance, and functionality goals of the processor. The AMD64 architecture employs a decoupled decode/execution design approach. In other words, decoders and execution units essentially operate independently; the execution core uses a small number of instructions and simplified circuit design for fast single-cycle execution and fast operating frequencies.

  The design implementation refers to a particular combination of physical logic and circuit elements that comprise a processor that meets the microarchitecture specifications.
