Chapter 21 Hardware Smart Probe Technology

As for the income of 2.15 million, 150,000 was used as my personal income, and most of the remaining 2 million was used to continue making tapes and registering the company.

In this way, the actual personal income is only 150,000 yuan, which can save a lot of personal income tax. Now that he is seriously short of money, he can only do this.

It just so happened that it was almost the end of the month, so he added the 150,000 yuan to the 8,000 yuan royalties he had obtained before, and paid a tax together. In the end, he only had more than 80,000 yuan left in his hands.

With the rest of the money, I went to Lenovo to buy a desktop computer of the foreign brand IBM that it represented. It cost 17,000 yuan, and I only had 70,000 yuan left in my hand.

I originally planned to buy a printer, but after thinking about it, I decided to forget it. A printer costs several thousand, so I might as well take it outside to print.

Although the unit price is a bit high, he has no plans to print other things besides printing books, which is not very cost-effective overall.

Moving the computer to the dormitory immediately caused a huge commotion. No one had seen a computer before, and he was the only one in the dormitory who had a computer.

So the news of his purchase of a computer spread like wildfire, causing a large number of students to come to see the surprise. Fortunately, he had already expected such a situation.

He clearly remembers that when he was young, a cadre family in the village bought a TV, and almost all the people in the village went to watch it. It was no different from this one.

Computers in this era are really too heavy. The total weight of the mainframe alone is as high as 27 kilograms, and the big butt monitor also weighs nearly 20 kilograms.

After the machine was installed, it started up immediately, and there was no accident in the middle, which made him relieved, at least it avoided a lot of trouble.

The semiconductor technology of this era, due to the backwardness of the packaging technology, is easy to break, and the protection of the computer is also very high, not like the later generations, where you just put it and don't care.

The operating system installed on the machine is Microsoft's DOS system. I saw him quickly operate on the DOS system and install the wps software for writing documents.

Then he started to use this document software, and found that there was a big gap compared with later generations, and he was even a little unaccustomed to using it, which gave him an urge to write one himself.

He also had to install a C language editor and related compilers, which took him a lot of time, and it took him an afternoon to get it done with just a few software.

In this era, not only the operating system needs the command line to operate, but even these application software cannot be separated from the command line. Even for him, it is too troublesome to operate.

As for the classmate who stood behind him and watched him operate, there were only two thoughts in his heart at this moment, the first was that the computer was so difficult, and the second was that Ye Zishu was so powerful.

After everything was done, he didn't know what to do for a while, whether to continue writing the book, or put it aside and write an operating system by himself.

In order to increase the popularity of computers in China, in addition to reducing the price of computers, it is also necessary to lower the threshold for using computers. This is imperative.

At present, from the operating system to the application software, they are basically foreign, and the interface is in English. For this reason, Lenovo has also developed a Chinese card, which is to Sinicize the operating system.

Just this is not enough, only some menus are Sinicized, but the command line actually used cannot be Sinicized, and the threshold of use cannot be lowered much.

But developing an operating system is not easy. In addition to the large amount of code, there is also a need to have a full understanding of the underlying technology, and even hardware manufacturers to provide relevant support.

The amount of code may not be a problem for him, because in this era, an operating system with a few million lines is enough. Except for the key parts, most of them are actually not very technical.

The hardest part is the support of hardware manufacturers.

With his current situation, it is basically impossible to obtain the support of the manufacturer.

If there is no support from the hardware manufacturer, even if it is barely written, the compatibility will be much worse, and the performance of the hardware will not even be fully utilized.

This is only for other people, but for him, there is a way to solve this problem. He even thought about this problem a long time ago.

Because if we want to develop our country's software technology and Internet technology, the operating system will be an unavoidable problem, and it will also be a problem that may be restricted in the future.

However, computer hardware is basically in the hands of foreign companies. Even if he has the technology in his hands, he cannot enter this industry with his current strength.

So how to develop our computer operating system has been a problem he has often thought about in the past 10 years, and he has also found a solution.

The first thing to solve is the problem of software and hardware adaptation. He has prepared the hardware smart probe technology, which can detect the hardware interface through the smart probe without harming the hardware.

The second is to solve the problem of writing language. Most operating systems are written directly for hardware, using C language and assembly language.

Finally, there is the problem of application software development language, which is basically C language, but C language is not only difficult to learn, but also not easy to use well.

Given the number of highly educated people in our country, if C language is used to develop, there are not many people who are competent. This not only increases the cost of software development, but also further narrows the scope of talents.

So before developing the operating system, he planned to develop a language, similar to the cross-platform language of the previous life, but it could directly target the underlying applications, and the efficiency was not lower than the C language.

The basis of this cross-platform language is the intelligent probe technology mentioned above, which solves the communication between hardware and software well, and is intelligent. It is much less difficult to develop on this basis.

I saw him open the notepad and start typing 0101 and other numerical codes on it, making the students who watched the excitement feel like they were reading a bible.

It is precisely because these are byte codes that he is not afraid of others seeing them, because he can't see why they see them. After a while, the entire notepad is filled with such codes.

"Ye Shu, what do these mean?" One of his roommates couldn't help asking.

"Machine code, all operations of the computer are performed by these machine codes composed of 0 and 1, but these things are blocked, and what you don't see are these English characters." Leaf Book explained.

Since the entire hardware smart probe software is in his mind, it is just a copy of the code in his mind, so writing these 0s and 1s is not too difficult for him.

The students who were watching the scene lost interest immediately when they saw that he was just writing 0 and 1 non-stop. Even a few students who were still interested left because they didn't understand.

Immediately, the dormitory became quiet. All the roommates knew his habits. As long as he was working, they would not make too much noise. They would either read quietly, sleep well, or go out for a night.

According to his current input speed, it will take 10 days to copy the smart probe code, and the amount of code is not too high.

Because its function is not complicated, it can be said to be a kind of hacking technology, but it is only aimed at the hardware, and it is not enough to rely on it alone.

After the smart probe is completed, he still needs to build a set of interfaces on this basis. Below the interface are the hardware parameters and commands obtained by the probe to detect the hardware.

These interfaces are provided for upper-layer calls. Relying on this interface set, the operating system kernel can be formally developed.

And he plans to rely on this interface set to build a virtual layer, or a virtual machine, so that the language he writes can be used by relying on this virtual machine.

Then use this development language to write the operating system, which is very different from the cross-platform language of the previous life. Undoubtedly, his method makes the language more powerful and more efficient.
