CPUMikroarchitekturkompatibilität
CPUMikroarchitektur, often shortened to CPU microarchitecture, refers to the specific implementation of an instruction set architecture (ISA) in a central processing unit (CPU). While the ISA defines the set of instructions a processor can understand and execute, the microarchitecture dictates how those instructions are physically processed. This includes the design of the internal components such as the arithmetic logic unit (ALU), control unit, registers, and the pipeline stages. Different microarchitectures can implement the same ISA but achieve varying levels of performance, power efficiency, and feature sets.
Key aspects of microarchitecture design involve optimizing instruction fetching, decoding, execution, and retirement. Techniques like pipelining,
Major CPU manufacturers like Intel and AMD continuously develop new microarchitectures for their processors. For example,
