Diagram of the Intel Core 2 microarchitecture. In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. [1]
reengineered P6-based microarchitecture used in Intel Core 2 and Xeon microprocessors, built on a 65 nm process, supporting x86-64 level SSE instruction and macro-op fusion and enhanced micro-op fusion with a wider front end and decoder, larger out-of-order core and renamed register, support loop stream detector and large shadow register file.
AMD Zen+ Family 17h – revised Zen architecture (optimisation and die shrink to 12 nm). AMD Zen 2 Family 17h – second generation Zen architecture based on 7 nm process, first architecture designed around chiplet technology. [3] AMD Zen 3 Family 19h – third generation Zen architecture in the optimised 7 nm process with major core redesigns. [4]
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
The micro-architecture is a step closer to the hardware. It implements the architecture and defines specific mechanisms and structures for achieving that implementation. The result of the micro-architecture phase is a micro-architecture specification which describes the methods used to implement the architecture.

Microarchitecture simulation is an important technique in computer architecture research and computer science education. It is a tool for modeling the design and behavior of a microprocessor and its components, such as the ALU, cache memory, control unit, and data path, among others. The simulation allows researchers to explore the design space ...
