Von Neuman
NEUMANN, JOHN VON, is one of the most outstanding mathematicians in the 20th century. In 1945, the design idea of "program memory" computer was proposed in 1945. This superior idea lays the foundation for the logical structure design of the electronic computer, has become the basic principles of computer design. He was known as "the father of computer" because of his great contribution to computer logical structure.
Novamman was born in Budapest in Hungary in 1903. He is a digital godman, which has shown mathematical talent at the age of 11. The 12-year-old Novan has a general public in the field of the aggregation, the analysis of the pragmatic analysis. In the youth, Nobeman from the famous mathematician Hilbert, since then, he is like a fish, and swim in the ocean in the ocean. After getting a doctors, he became the first former professor at the University of Princeton, that, then he was less than 30 years old.
Nobmann is not only a mathematical genius, but also build a tree in other fields. He is proficient in seven languages, and has a considerable accomplishment in chemistry, and has been a degree from the Department of Chemistry, China University of Higher Education. It is even more rare that he is not limited to pure mathematics research, but applies mathematics to other disciplines. He has conducted a deep study of classic, quantum mechanics, and fluid mechanics, and gains major achievements. These all have the foundation of Novan has a solid-mathematical basis, and the knowledge of Guangbo, which is later engaged in computer logic design. Strong backing.
In 1944, Novan participated in the development of the original bullet, which involved extremely difficult calculations. In the study of the atomic nuclear reaction process, "Yes" or "NO" answer to a reaction is propagated. Solving this problem typically requires a few billion mathematical operations and logic instructions, although the final data is not required to be very accurate, all intermediate arithmetic processes are indispensable, and they must be as accurate as possible. His Lozis Alamos laboratory hired more than 100 female calculations, using desktop computers from early late to late, or far could not meet the needs. Endless numbers and logic instructions like the deserts like the desert.
Novanman who was bothered by the computer in an extremely accidental opportunity, and since then he got into the computer to develop this magnificent career, establish a biggest great achievement in his life.
On the summer of 1944, Novan, who was waiting at the train station, Qiao Gordan, and a short conversation with him. At that time, Gordan was the military person in charge of the US Ballistic Lab, which is involved in the development of ENIAC computers. In the conversation, Gordan told NuMan to develop the ening. Novanman with vision is attracted to this development plan, and he realizes the far-reaching meaning of this work.
A few days later, Nobieman came to the Moer College, visited this huge machine that has not yet completed, and grabbed the computer's soul - logical structure problem with its keen vision - logical structure problem, making young Eniac The developments have admired.
For the strong desire to calculate in actual work and the strong desire to apply mathematics to other scientific issues, Novaman quickly decided to get into the ranks of computer developers. Novanman, who has been named, this is a great courage, because this is a new journey of success or failure. Once failed, it will affect his reputation and status. Novann made a first step in the way to the future of the new things, and decided to take the first step in June 1944, joined the Moore Computer Development Team to open a brilliant page for the computer.
Nobiman has made a series of excellent design ideas with its long-term analysis, comprehensive ability and strong mathematics, and raised a series of excellent design ideas. Under the joint efforts of other members of the Moore group, only shortcomings. Ten months, human beings accumulated scientific and technological civilization in thousands of years, finally gave birth to the most exciting wisdom of wisdom - a new storage program General Electronic Computer Program (EDVAC Program) was born. Nobeman drafted the summary report of up to 101 pages with the draft report of Edvac. The report has been widely introduced to the new idea of manufacturing electronic computers and programming. The report clearly stipulates that the EDVAC computer consists of most of the calculator, logic control, memory, input, and outputs, and expounds these five major functions and interrelationships. This report is a discipline literature in the history of computer development, which announced to the world: the era of electronic computer began.
In June 1954, Novan went to the US Princeton Institute of Princedon, served as the director of the ISA computer development group. At that time, he proposed a more complete design report "a research on the logic structure of electronic computing device." In the report, Novan made a further demonstration of two major design ideas in Edvac, and set a milestone for the design of the computer.
One of the design thoughts is binary, and he is recommended to use binary in the electronic computer according to the characteristics of the two stable work of electronic components. The report refers to the advantages of binary, and prophesies that binary uses to simplify the logic lines of machines.
Practice has proved the correctness of Neuman prophecy. Today, the application of logical algebra has become an important means of designing electronic computers, and the main logic lines used in Edvac have been used, but improved the analysis and logic circuit of logic lines.
The program memory is another Jie, another master of Neuman. Through the inspection of Eniac, Neuman has grasped its maximum weakness - there is no real memory. ENIAC is only 20 telecommunications, and its program is an external plug, and the instruction is stored in other circuits of the computer. In this way, before the problem, the full instructions needed to be preceded, and the corresponding circuit Unicom is handled by manual. This preparation will take hours or even a few days, while calculating itself takes a few minutes. The calculated high-speed and procedures have a big contradiction.
In response to this problem, Neuman puts forward the idea of program memory: in the memory of the machine, the program designer only needs to find the operation instruction in the cloud memory, which will calculate itself, so that you don't have to re-every problem. Programming, greatly accelerating the process of operation. This idea marks the implementation of the automatic operation, marking the maturity of the electronic computer, has become the basic principle of electronic computer design.
Von Novan turned a road in the road of development. Despite the long-term, the power of the inventive inventory of binary and program memory has always been controversial, but the excellent contribution made by Neuman's overall configuration and logic design set off a computer boom. Proven the development of the electronic computer. He is worthy of the "father of computer".
