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.
Von Neumann describes a detailed design of a "very high speed automatic digital computing system." He divides it into six major subdivisions: a central arithmetic part, CA; a central control part, CC; memory, M; input, I; output, O; and (slow) external memory, R, such as punched cards, Teletype tape, or magnetic wire or steel tape.
Neumann, John von: Formulated the von Neumann architecture upon which most modern computers are based. 1956 Newell, Allen: Together with J. C. Shaw [43] and Herbert Simon, the three co-wrote the Logic Theorist, the first true AI program, in the first list-processing language, which influenced LISP. 1943 Newman, Max
Little Man Computer simulator. The Little Man Computer (LMC) is an instructional model of a computer, created by Dr. Stuart Madnick in 1965. [1] The LMC is generally used to teach students, because it models a simple von Neumann architecture computer—which has all of the basic features of a modern computer.
It is an example of the so-called von Neumann architecture and is closest to the common notion of a computer. Together with the Turing machine and counter-machine models, the RA-machine and RASP-machine models are used for computational complexity analysis.
The model describes how units of computations, memories, and communications are organized. [3] The computational complexity of an algorithm can be measured given a model of computation. Using a model allows studying the performance of algorithms independently of the variations that are specific to particular implementations and specific technology.
The immutable capability keys, exclusive to six Church instructions, navigate the computational context of a Turing machine through the separately programmed structure of the object-capability model. Immutable capability keys represent named lambda calculus variables. This Church side is a lambda calculus meta-machine. The other side is an ...
Starting with an examination of the learning process in organisms, Wiener expands the discussion to John von Neumann's theory of games, and the application to military situations. He then speculates about the manner in which a chess-playing computer could be programmed to analyse its past performances and improve its performance.
