Early Stored Program Computers
Stored Program Computers Thomas J. Bergin Computing History Museum American University 7/9/2012 1 Early Thoughts about Stored Programming • January 1944 Moore School team thinks of better ways to do things; leverages delay line memories from War research • September 1944 John von Neumann visits project – Goldstine’s meeting at Aberdeen Train Station • October 1944 Army extends the ENIAC contract research on EDVAC stored-program concept • Spring 1945 ENIAC working well • June 1945 First Draft of a Report on the EDVAC 7/9/2012 2 First Draft Report (June 1945) • John von Neumann prepares (?) a report on the EDVAC which identifies how the machine could be programmed (unfinished very rough draft) – academic: publish for the good of science – engineers: patents, patents, patents • von Neumann never repudiates the myth that he wrote it; most members of the ENIAC team contribute ideas; Goldstine note about “bashing” summer7/9/2012 letters together 3 • 1.0 Definitions – The considerations which follow deal with the structure of a very high speed automatic digital computing system, and in particular with its logical control…. – The instructions which govern this operation must be given to the device in absolutely exhaustive detail. They include all numerical information which is required to solve the problem…. – Once these instructions are given to the device, it must be be able to carry them out completely and without any need for further intelligent human intervention…. • 2.0 Main Subdivision of the System – First: since the device is a computor, it will have to perform the elementary operations of arithmetics…. – Second: the logical control of the device is the proper sequencing of its operations (by…a control organ. -
Computer Organization & Architecture Eie
COMPUTER ORGANIZATION & ARCHITECTURE EIE 411 Course Lecturer: Engr Banji Adedayo. Reg COREN. The characteristics of different computers vary considerably from category to category. Computers for data processing activities have different features than those with scientific features. Even computers configured within the same application area have variations in design. Computer architecture is the science of integrating those components to achieve a level of functionality and performance. It is logical organization or designs of the hardware that make up the computer system. The internal organization of a digital system is defined by the sequence of micro operations it performs on the data stored in its registers. The internal structure of a MICRO-PROCESSOR is called its architecture and includes the number lay out and functionality of registers, memory cell, decoders, controllers and clocks. HISTORY OF COMPUTER HARDWARE The first use of the word ‘Computer’ was recorded in 1613, referring to a person who carried out calculation or computation. A brief History: Computer as we all know 2day had its beginning with 19th century English Mathematics Professor named Chales Babage. He designed the analytical engine and it was this design that the basic frame work of the computer of today are based on. 1st Generation 1937-1946 The first electronic digital computer was built by Dr John V. Atanasoff & Berry Cliford (ABC). In 1943 an electronic computer named colossus was built for military. 1946 – The first general purpose digital computer- the Electronic Numerical Integrator and computer (ENIAC) was built. This computer weighed 30 tons and had 18,000 vacuum tubes which were used for processing. -

1 The Function of Computation As in music theory, we cannot discuss the microprocessor without positioning it in the context of the history of the computer, since this component is the integrated version of the central unit. Its internal mechanisms are the same as those of supercomputers, mainframe computers and minicomputers. Thanks to advances in microelectronics, additional functionality has been integrated with each generation in order to speed up internal operations. A computer1 is a hardware and software system responsible for the automatic processing of information, managed by a stored program. To accomplish this task, the computer’s essential function is the transformation of data using computation, but two other functions are also essential. Namely, these are storing and transferring information (i.e. communication). In some industrial fields, control is a fourth function. This chapter focuses on the requirements that led to the invention of tools and calculating machines to arrive at the modern version of the computer that we know today. The technological aspect is then addressed. Some chronological references are given. Then several classification criteria are proposed. The analog computer, which is then described, was an alternative to the digital version. Finally, the relationship between hardware and software and the evolution of integration and its limits are addressed. NOTE.– This chapter does not attempt to replace a historical study. It gives only a few key dates and technical benchmarks to understand the technological evolution of the field. COPYRIGHTED MATERIAL 1 The French word ordinateur (computer) was suggested by Jacques Perret, professor at the Faculté des Lettres de Paris, in his letter dated April 16, 1955, in response to a question from IBM to name these machines; the English name was the Electronic Data Processing Machine. -
