Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1]
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
The 8088 version, with an 8-bit bus, was used in the original IBM Personal Computer. 186 included a DMA controller, interrupt controller, timers, and chip select logic. A small number of additional instructions. The 80188 was a version with an 8-bit bus. 286 first x86 processor with protected mode including segmentation based virtual memory ...
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.
A modern consumer CPU made by Intel: An Intel Core i9-14900KF Inside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006. A central processing unit (CPU), also called a central processor, main processor, or just processor, is the most important processor in a given computer.
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]

Processor design is a subfield of computer science and computer engineering (fabrication) that deals with creating a processor, a key component of computer hardware.. The design process involves choosing an instruction set and a certain execution paradigm (e.g. VLIW or RISC) and results in a microarchitecture, which might be described in e.g. VHDL or Verilog.
