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]
An example block diagram, showing the Microsoft Windows 2000 operating system architecture. A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1]
English: Block diagram of a hypothetical simple CPU, showing instruction fetch, decode, data registers, ALU, and memory interface, and major relationships. Español: Diagrama de una hipotética y simple "Unidad Central de Proceso" (CPU), mostrando la captura de una instrucción y su decodificación, así como los registros de datos, la "Unidad ...
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.
Block diagram of a basic uniprocessor-CPU computer. Black lines indicate data flow, whereas red lines indicate control flow; arrows indicate flow directions. Hardwired into a CPU's circuitry is a set of basic operations it can perform, called an instruction set. Such operations may involve, for example, adding or subtracting two numbers ...
Block diagram of an example CPU showing data paths for ALU operand sources and result destinations. The sources of ALU operands and destinations of ALU results depend on the architecture of the encapsulating processor and the operation being performed.
Hack Computer Block Diagram. The Hack computer hardware consists of three basic elements as shown in the block diagram. There are two separate 16-bit memory units and a central processing unit (CPU). Because data is moved and processed by the computer in 16-bit words, the Hack computer is classified as a 16-bit architecture.
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
