Chapter 1089： The first computer (2/2)
In history, Eniac occupies an area of 150 square meters. Compared with this kind of electronic tube computer, the volume of the transistor is much smaller.
”Our first-generation computer uses 17,000 transistors, 600 tubes, 6,000 switches, 7,000 resistors, 10,000 capacitors, 500,000 wires, and consumes 14 kilowatts of power, which can perform 5,000 additions per second. ”Dr. Ferrols said to Cyric.
Although a large number of transistors are used, in some circuits, electron tubes are indispensably needed. Such circuits are still relatively large, but they can perform 5,000 operations per second, which is quite an amazing result. He is very satisfied.
Cyric nodded and watched the behemoth humming. The fan in the cabinet was dissipating heat. Cyric looked at the paper tape on one side and was spitting it out continuously, printing the results.
Today's computers are different from later generations. They have no keyboard, no display, and input and output. They all rely on punched paper tape. Of course, this efficiency is low.
Cyrek, who was born in engineering, still knows something about it. Now that electronic computers have just come out, they can use paper to bring input and output, but it is quite inconvenient.
Although various fool-like program tools of later generations are still impossible to achieve, the initial stage should be considered.
”We can invent an assembly language.” Cyric said: ”In a computer, first design a compiler that uses mnemonics to replace the opcodes of machine instructions, and address symbols or labels to replace instructions or operand addresses. In this way, we can speed up the data input by a hundred times.”
The paper tape records zeros and ones, which is quite cumbersome. If you use one language to describe it, it would be much more convenient! Cyric had studied PLC in his previous life~~ and was familiar with this kind of assembly language, so I told it now: ”For example, we use SHL to represent the logical shift left instruction, followed by The number represents a few bits shifted to the left, and you can directly perform calculations.”
Cyric said only this point, and Dr. Filaus had already understood it. Before his eyes, it seemed that something like a keyboard for a typewriter had appeared, and a conversion circuit was installed between the keyboard and the computer. It can be achieved!
This will greatly improve efficiency and reduce the chance of error. The input and output are all perforated paper tapes, which is quite cumbersome.
”Head of Cyric, your wisdom really makes us admire.” Dr. Ferrols' eyes gleamed and said to Cyric.
This is where the advantage of the traverser lies. For Cyric, as long as the most obvious ones of later generations are taken out, it is a new idea one by one, and it is absolutely correct, the survival of the fittest, and the wrong ones have long since disappeared in the long river of history.
”I hope you guard against arrogance and rashness, continue to develop new computers, simplify input and output, and your contribution to the empire will be written in history.”
These few people will definitely enter the history book. Cyric knows very well that the appearance of electronic computers has completely changed the entire world. At least for now, it is not only the ballistic calculation of ballistic missiles. If it is improved, it can be installed on warships for fire control calculations. When the size is reduced again, it can be installed on airplanes or even tanks.
”Head of Führer Cyric, a new situation has emerged in the Balkans. The Greeks have already reached Albania.” After the inspection at the University of Munich and returned to his car, an adjutant came to report to Cyric. ()
