The technique of microprogramming as first described by Maurice Wilkes in terms of a second diode matrix added to a diode matrix control store. [2] Later computers used a variety of alternative implementations of the control store, but eventually returned to a diode matrix or transistor matrix.
Sir Maurice Vincent Wilkes (26 June 1913 – 29 November 2010 [11]) was an English computer scientist who designed and helped build the Electronic Delay Storage Automatic Calculator (EDSAC), one of the earliest stored program computers, and who invented microprogramming, a method for using stored-program logic to operate the control unit of a central processing unit's circuits.
In 1951, Maurice Wilkes [15] enhanced this concept by adding conditional execution, a concept akin to a conditional in computer software. His initial implementation consisted of a pair of matrices: the first one generated signals in the manner of the Whirlwind control store, while the second matrix selected which row of signals (the ...
Maurice Fernand Cary Wilks (19 August 1904 – 8 September 1963) was an English automotive and aeronautical engineer, and by the time of his death in 1963, was the chairman of the Rover Company. He was the founder of the Land Rover marque and responsible for the inspiration and concept work that led to the development of the first Land Rover ...
Under the advice of Maurice Wilkes (1913–2010), LEO was designed by John Pinkerton (1919–1997) and David Caminer (1915–2008). 1951: Concept of microprogramming developed by Maurice Wilkes (1913–2010) from the realisation that the central processing unit (CPU) of a computer could be controlled by a miniature, highly specialised computer ...
[citation needed] Maurice Wilkes and a team at Cambridge University executed the first stored program on the EDSAC computer, which used paper tape input–output. Based on ideas from John von Neumann about stored program computers, the EDSAC was the first complete, fully functional von Neumann architecture computer.
Published in 1951, it was written by Maurice Wilkes, David Wheeler, and Stanley Gill of Cambridge University. The book was based on the authors' experiences constructing and using EDSAC, one of the first practical computers in the world.
First, the report was later ruled a public disclosure that occurred more than a year before the EDVAC patent application was filed, thereby rendering the eventual patent unenforceable; second, some on the EDVAC design team contended that the stored-program concept had evolved out of meetings at the University of Pennsylvania's Moore School of ...
