Chapter 325 Programmable Computer
Institute of Computer Science.
Fairy Mingcen's research room.
Ever since Wang Xiaoya submitted the method that "you can write formulas and functions by yourself", Xu Mingcen and the others have been busy.
However, unlike before, this time they did not mechanically input the formula into the formation, but wanted to come up with a set of lower-level things, and wanted to solve the problem of formula diversification once and for all.
Think about it, fixed formulas can only be used for special purposes, and if a lower-level set of things is designed to support the above set, isn't this the general-purpose computer they want?
With the direction in hand, all the formation-related weapon refiners in the institute united together and planned to implement it according to Chen Qingxuan's instructions.
After all, no matter what, the feasibility of Qingxuan's "store the formula and then read and execute it" is quite high.
The trouble now is, how to store, how to read, and how to execute?
Storage and reading are easy to solve. These two are mutually exclusive. As long as certain storage and reading rules are set, it can basically be solved quickly.
During the period, a refiner named Wang Jiahe said that the entire Yin-Yang rune piece can be divided into several regular data units.
Each unit can be represented by 64 continuous small squares.
(horizontal) In this case, as long as 64 are read each time, there will be no confusion.
Moreover, 64 small squares can theoretically have two to the power of 64 possibilities, which is enough to theoretically include all symbols, numbers, words, languages, etc., so it is enough for a short time.
(Mainly numbers, because of the need for deduction, the accuracy here must be very high, otherwise sixteen digits, or even eight digits, may be enough) With this idea in mind, they joined forces with the Institute of Arithmetic to unify the rules for various numbers, characters, and symbols.
It has become a standard, and it is planned that all future computers will be implemented on this.
In this way, even if the computer is upgraded in the future, these data will not be lost.
There will be no compatibility issues.
Of course, because the early computers could only read sequentially, they also invented positioning reading technology for higher reading efficiency.
That is to say, it could only read from the first row and column before, but now you can specify which row and column.
In this way, the computer has more possibilities to branch and loop.
Without exception, these have laid a firm foundation for the subsequent execution part.
It is still the previous 64 symbol part.
They specially designed hundreds of special symbols to mark the program, that is, which step has the computer executed? Should the calculation continue in the next step, or should the calculation result be stored directly?
Is it reading the program, or is it displaying the results directly? Should the two digits be added directly, or should they be cleared directly? All in all, it's all very low-level stuff.
As for the four arithmetic operations, there are square roots, exponent calculations, trigonometric functions, etc., but they made another set of programs to realize it by calling the previous basic instructions.
In Qingxuan's words: the calculation methods of various calculations are not necessarily optimal now, in case there is a more convenient method in the future, if the four arithmetic operations and basic instructions are separated, it can be directly updated on the old machine Replacement without having to return the machine to redo it again.
save resources.
Regarding this, Xu Mingcen thought about it carefully and found that there was indeed some truth.
Anyway, they have to come up with a formula that can change at any time, so it's better to try this first.
After experimenting, they found that this really works.
Moreover, the yield rate of computers has been greatly improved, reaching almost [-]%.
I believe that after a while, when you become proficient, even if it is [-]%, it will not be a problem.
After the four arithmetic operations are done, the last part is left, which is the problem of function formulas.
On this day, Xu Mingcen directly invited Wang Xiaoya and others to the laboratory, and then handed each of them a manual to let them program by themselves.
That's right, it's programming.
Xu Mingcen and the others have completely figured out the bottom-level method, and even the four arithmetic operations and exponent extraction have been designed. As for what kind of calculation process the other party will use it to achieve next, then they can't care about it.
Anyway, write it, write it, and break it down to the bottom layer, which is just a few algorithms.
In this way, Xiuxian version computer ushered in the first batch of programmers.
In the laboratory, Wang Xiaoya and others were studying and testing at the same time.
It didn’t take long for them to learn all the dos and don’ts of programming.
After they learned it, they started to write programs by themselves, and wrote all the previous calculation formulas.
And this writing, they discovered the advantages of this computer.
Don't be afraid to make mistakes! That's right, this kind of computer is not afraid of mistakes in the process of inputting formulas at all.
Even if something is really wrong, just delete it and start over.
Unlike before, as long as there is the slightest mistake, the entire formation has to be scrapped.
As for the second advantage, it can be modified continuously.
That's right, mathematical formulas, it's impossible to figure out the simplest and most efficient method at needs to be iterated step by step.
The original computer completely obliterated this possibility.
Now, just modify it directly in the program, which is simple and convenient.
As for the third day, the operation process was greatly simplified.
The current program is that as long as it is written, it can be placed there forever, and when you want to use it, you can directly input the relevant data.
And if you want to change the data, you can modify it directly on the program and re-execute it after you are done. It is indeed much more convenient than before.
The most important thing is that in order to facilitate the spread of the well-written level and avoid repeated writing, Xu Mingcen and the others also modified the jade slip and turned it into a mobile hard disk.
Whenever you need to copy, just plug it in, copy the program in it, and then "follow the gourd" to copy it to another computer.
In this way, the waste of manpower is further avoided.
Only a few people who are proficient in programming are needed to write the program, and with a few operators responsible for inputting data, all the work that previously required hundreds of people can be done.
As for the rest, they can save their energy and invest it in algorithm simplification, formula improvement, and other arithmetic research.
For a time, the new computer was warmly welcomed by all monks.
The same treatment is given to researchers who have learned programming.
Calculation program for alchemy, testing program for refining equipment, program for analyzing spells, program for standardizing spells...
All in all, each department wants to develop their own special programs as soon as possible to assist research.
At the same time, the Institute of Arithmetic is also quickly analyzing all known spell models at the rate of one spell every three days.
[Spiritual Shield Technique] [Heavenly Eye Technique] [Grass and Tree Jue] [Gengjin Jue] [Royal Sword Art] [Li Huo Art]...
These are all quickly analyzed and resolved without exception.
Affected by this, many monks who had not learned the relevant spells quickly imprinted these spells into the sea of consciousness.
It's just that for some reason, there has never been a perfect state spell born.
In this regard, everyone no longer struggled with it, but divided a group of candidates to study this matter specifically.
As for the others, they shifted their focus to alchemy formulas, weapon refining formulas, and even kung fu formulas.
Before, they realized that these formulas and spells have some commonality in the runes. Now that they have the opportunity to solve it, the monks on the island will naturally not let it go.
At the same time, in order to cultivate more qualified programmers, the family also began to teach related courses in various colleges.
Jingnancheng First College.
A group of students surrounded the new machine on the podium with eager eyes.
"This is a computer, it really is not ordinary!"
"Of course! Look at this keyboard, look at this water curtain, look at this fuselage, it's just made of spiritual stones, how can it be average!"
"I heard that this machine alone can outperform several arithmetic masters. Is it true?"
"Of course it is true! My mother is at the Institute of Arithmetic. I heard from her that a difficult problem that used to require hundreds of researchers to calculate for dozens of days can now be solved in just one or two days. And only one professional programmer is needed ."
"so smart?"
"That's not true! I heard that this computer can calculate millions of breaths per breath. It's amazing! My mother also said that she didn't even have one. I didn't expect our school to have one. We really are the future of the family. !"
"The future of the family? Then let me take a good look at this future!"
For a time, all the students were looking around and around the podium.
After a long time, a class bell rang, and everyone returned to their seats reluctantly.
Just then, a rather young teacher walked into the classroom.
"Students, starting today, we will open a new course - computer programming."
"Everyone should have heard of the usefulness of computers, but you may not understand it very deeply. Here, I will repeat a sentence from the vice president of the research institute:
Computing power can do anything. If you can't do it, it only means that your computing power is not enough. "
“And our computer is the representative of computing power.
Now, it can operate millions of times per breath, which greatly exceeds human power, but we all believe that in the near future, we will be able to break through again and increase it to tens of millions, [-] million, or even trillion times.
At that time, maybe we will be able to deduce what is a spiritual root?
Why can only spiritual roots be cultivated? Why can you increase your lifespan and even ascend to immortality as long as you break through? Therefore, whether it is for the sake of the family or for yourself, you must study hard and strive to make our computing industry advance by leaps and bounds and rise strongly.
Tell me, okay? "
"it is good!"
All the students spoke in unison.
The answer was passionate! Cultivating immortals and spiritual roots, this is indeed what they desire most, and it is very possible to achieve all of this through computers and the unimaginable computing power.
What's more, even if it can't be realized or popularized, it is a good result to make a lot of contributions in this process and enter a "sleep state" to wait for the right time.
I didn't see that the master named "Wang Xiaoya" got a lot of rewards through this computer, and even made up enough for Shen Mian's expenses!
If they are also so lucky and capable, then naturally they can do it too.
Thinking of this, everyone was even more excited.
Not only themselves, but also their parents, sisters, brothers, and even teachers and friends are qualified to cultivate immortals, so that they can be happy forever.
Seeing their enthusiasm, the teacher on the stage smiled with satisfaction and said loudly: "If you want to learn computer programming well, you must first understand the principles of computers.
So our first lesson is: the composition and design of computers! Please watch the big screen! "
At this point, I saw the teacher lightly touching the water screen. Suddenly, the entire computer screen quickly enlarged and was faithfully projected onto the blackboard in front of me.
In the center of the blackboard, there are several large characters "Computer Composition".
The major components of the computer are listed below.
Keyboards, screens, computing cores, controllers...
Next to the text, there are also related pictures.
Even, relying on the power of finger sliding, the entire screen can be moved at will, and can be zoomed in and out.
Seeing this, the students below all widened their eyes.
When had they ever seen such a magical scene? Even though they had heard about the magic of computers from the people around them, they were still inexplicably shocked when they saw such a scene.
This, even if it is compared with the legendary spell, it is not much different, right? For a while, everyone's curiosity was mobilized again.
They listened more attentively and attentively.
……
Contrary to them, at this moment, Chen Qingxuan was idle, and came to the theater with his daughter in his arms, and began to watch the play.
At this time, the opera was reaching its first climax.
I saw a beautiful woman teaching her naughty son a lesson.
"Son, you are young and ignorant. Don't you know that youth is the best time to make progress? You must not delay it. Today, I will spank you once. I hope you will remember the lesson and stop playing around."
As she spoke, she picked up the bamboo board and was about to teach her son a , the son grabbed her hand and contradicted: "You are not my own mother, why beat me!"
For a moment, the woman was so angry that she cried.
Next is the scene where the old housekeeper returns, comforts Sanniang and touches the playful son.
On the stage, everyone was engaged in the performance, and off the stage, the audience was also fascinated.
But at this moment, a childish voice came from behind the stands.
"Hit him, beat him! Beat this disobedient brat to death!"
Everyone took a closer look and saw a pretty little girl waving her fists with angry eyes, as if she wanted to go up and teach her disobedient son a lesson.
Seeing this, Qingxuan quickly apologized, pulled his daughter into his arms and sat down.
This little girl, who is disobedient herself, is really a top two when she teaches others a lesson!
When the people on the side saw this, they laughed even more.
Whose little girl is so sensible!
so cute!
