    School of Physical Electronics, School of Optoelectronic Information, School of Computer Science and Engineering, School of Information and Software Engineering, School of Automation Engineering, School of Life Science and Technology.  Zhang Donglai silently watched the school settings at the campus entrance, and had a general understanding of the focus of the University of Electronic Science and Technology of China.  Among the six colleges, only the School of Physics and Electronics is considered a purely theoretical college, while the others are practical subjects.  This cannot be said that the founding purpose of the University of Electronic Science and Technology does not pay attention to theoretical research, but pays more attention to the practical application of electronic technology, but the focus can also be seen.  The sheer number and variety of laboratories on display made him tremble slightly.  &{;Communication Anti-Interference Technology Laboratory, Microwave Electric Vacuum Device Laboratory, Electronic Thin Film and Integrated Device Laboratory, Electromagnetic Radiation Control Material Research Laboratory, Neural Information Research Laboratory, Optical Fiber Sensing Communication Laboratory, Optoelectronic Sensing and  Optoelectronic Integration Technology Laboratory There are no less than twenty laboratories and centers, and the research direction is so advanced that it is the only one among other domestic scientific research institutions except the National Academy of Sciences!  Guan Fei¡¯s ambitions are lofty. What he wants to solve is not the shortage of successor technology R&D personnel in the northern theater, but to cultivate scientific research pioneers that surpass European and American technology!  Some of its subjects are only heard of abroad, and are the first of its kind in China, and the teaching materials are completely blank.  If UESTC can solve the teaching material problem, provide teachers and students with sufficient experimental opportunities, and keep the research direction on track, everyone who graduates in the future can be said to be a top talent that even the country will covet!  "Let's go! Let's go to the laboratory and have a look!" After reading the introduction board at the school entrance, he felt like a fire was lit in his heart. The burning fire made him unable to remain reserved anymore. He pulled Ge Hao and was about to go to the experimental building marked on the map.  Run.  "Professor Zhang, don't worry, we'd better go meet the school leaders first and say hello to them, otherwise you won't be able to enter the experimental building!" Ge Hao saw that he just looked at the introduction board and scanned the previous  He was graceful and calm, rushing like a young boy, and smiled unconsciously.  "Okay! Hurry up, hurry up!" Zhang Donglai also thought that what he said was reasonable, but he was anxious in his heart and couldn't help but urge him repeatedly. He pulled Ge Hao's sleeves, walked and ran at his feet, turned around and ran towards the office building.  The University of Electronic Science and Technology of China received the notice in advance, and the principal and secretary were already waiting. When they saw Zhang Donglai in military uniform, they warmly greeted him.  However, Zhang Donglai was obviously absent-minded. He barely said a few polite words to them and then asked to visit the experimental building.  "Of course there is no problem.  The two school leaders personally took him to the experimental building. Looking at the beautiful and stylish experimental building with glass exterior walls, Zhang Donglai felt uncontrollably excited again.  Guan Fei is really willing to spend money on scientific research and teaching!  It¡¯s just an experimental building. In China, we must be as frugal as possible, as long as it can be used roughly.  However, the luxury of the experimental building of the University of Electronic Science and Technology of China is simply better than that of a high-end hotel. Looking at the clear and transparent glass exterior wall and spiral staircase, it is a kind of enjoyment just to look at it from the outside.  Heartfelt envy.  Although such luxurious decoration is not helpful for scientific research itself, it is a kind of physical and mental satisfaction and pride for the scientific research and teaching staff involved.  No wonder those scientific researchers, technicians, and master craftsmen rarely go back after arriving here.  Even those who left mentioned the military division, Guan Fei and other high-level officials, and they praised him more than he criticized him. Guan Fei was really good at grabbing people's hearts.  Not only does he provide high wages, but more importantly, these people get the respect and sense of accomplishment they want here, allowing them to experience the dignity and pride of successful people in society, so they voluntarily stay here to shine and contribute to the care of people.  Fei's career further contributed to his contribution.  To be honest, even Zhang Donglai himself hopes to work in this beautiful experimental building. The prerequisite is that the experimental equipment here must be good enough and not be much worse than the top domestic laboratories Uh!  After he visited the laboratory building, Zhang Donglai¡¯s expression was dull.  Before entering, he also said that as long as the experimental equipment here is not too bad, more talents can be attracted to join.  But in fact, the advanced level of the equipment here almost astonished him: everything that is available in China is available here, with higher precision, more accurate measurement, and easier to use; there is also something here that is not available in China, and some of the instruments are even used for foreign electronic research.  Zhang Donglai, who was very familiar with the equipment, didn¡¯t even know what to do!  This is simply unbelievable.  This is just a university, not the best scientific research institution in Guan Fei's hands.  Do some homework before visitingZhang Donglai knew that there are three levels of scientific research institutions in the war zone. The top one is naturally Guan Fei's own laboratory, also known as the "Command Building"; the second is several research institutes; and the last is various universities.  This is too outrageous!  The equipment used in Guan Fei¡¯s worst experimental building is actually a fully digital precision instrument!  Although these are general-purpose scientific research equipment, it is still difficult for Zhang Donglai to accept. The psychological gap is really too big!  He is one of the top authoritative scientists in electronics in the country, but the scientific research equipment he uses is not as good as that of other universities. This is really shocking.  He knew that Guan Fei had accumulated a lot of wealth in the past few years, but he still found it unbelievable that his family's wealth was so rich.  In recent years, technology in China, Europe and the United States has been expanding, and now even the little brothers next door can¡¯t keep up.  As long as the experimental equipment is good, and the experimental regulations are normal, there is another aspect that hits him particularly hard.  That¡¯s why you can use experimental materials without restriction as needed!  Everyone knows that a laboratory is used for experiments. If you don¡¯t do experiments, why would you put so many instruments in there?  But who knows how much it costs to do an experiment!  Electricity bills, instrument depreciation, disposable consumables such as gloves, masks, catalysts, experimental materials everything costs money.  Some may seem small, but after doing dozens or dozens of experiments every day, a small amount adds up to a lot, and it is quite a lot over the years.  What costs more is precious materials. They can only be prepared in small quantities domestically and are extremely expensive to import. Each gram can be counted in hundreds, thousands, or even tens of thousands. An experiment costs thousands of dollars.  It¡¯s just a drizzle, and it¡¯s normal to spend tens of thousands.  Even foreign scientists who are used to spending a lot of money have only a few experiments on certain scarce materials.  But here, he saw that every laboratory inside was in use, and all the materials that he was reluctant to use were being used by people doing experiments.  The key is that these experiments are too low-level in his opinion! ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Many of the students are led by teachers to familiarize themselves with the equipment and understand the experimental procedures. Why can¡¯t you just pick cheaper materials? Why waste materials like this?  Through the visiting glass window, I watched the clumsy students in the laboratory, wasting precious experimental materials again and again, while the instructor stood aside and watched, only reminding the students when they made mistakes. Several times he  I almost couldn't help but want to rush in and teach the other person step by step how to do the experiment in the most economical, correct and least wasteful way.  Seeing his blushing face and angry expression, the principal and secretary of the University of Electronic Science and Technology of China laughed.  After their explanation, Zhang Donglai learned that they were not worried about money at all: most of the materials that seemed to be wasted casually were mass-produced by the war zone, and the cost was greatly reduced, so it didn't matter if it was wasted.  However, the war zone has not yet achieved self-production and requires the use of truly precious materials for experiments. The University of Electronic Science and Technology of China is usually very cautious and needs to apply in advance every time. Only a small amount will be allocated if the review deems it really necessary.  The secretary quoted Guan Fei as saying: "If these students only learn some knowledge from books in a few years, except for the words in the books, they are not familiar with the experimental equipment and do not understand the experimental procedures, they will not be able to do any practical work after graduation.  We have to cultivate it from scratch; we have never personally tried under what circumstances the knowledge in books is correct and under what circumstances it is wrong. What do nerds do with it when they completely regard book knowledge as a guideline and think it is sacred and inviolable truth?  Have you learned in vain these past few years? Don¡¯t be afraid of wasting a little or having the experimental equipment damaged. The key is that you have to train me people who can use it. If you can¡¯t do this, you are derelict in your duties as an educator!¡± The principal showed his hands!  , said with embarrassment and showoff: "There is a fixed amount of material fees and experimental equipment damage subsidies every month. If we don't use them up, we will be criticized, thinking that we are not doing our job well. So in order not to suffer  "Excuse me, we can only let the students do more seemingly useless experiments." Seeing his big, white and fat face smiling like a flower, Zhang Donglai could only twitch the corners of his mouth and watch in silence bitterly. He would never look at it again!  Too much talk.  The brother's unit next door is developing rapidly. It can be said that it is making great progress with each passing day.  Domestic scientific research funding has been repeatedly reduced. Comparing the two, he really feels like he is miserable.  He agrees that everything should make way for economic construction, but the price is not too high.  He is unknown.  After coming out of the experimental building, he originally planned to walk around the teaching building and leave in a hurry, but here, he heard something surprising again.  ¡°The inside of a computer processor is a bunch of circuits, and different circuits are designed for different purposes.The function of ?? is to realize scientific operations such as addition, subtraction, multiplication and division, square root and so on.  It itself is the on and off of the circuit, that is, 1 and 0. If we talk about the lowest level of computer language, it is 1 and 0. There is no so-called distinction between English and Chinese" When passing by the first-year freshman's classroom, he accidentally listened  In a certain classroom, it was heard that the teacher was teaching, and after listening, he nodded slightly. Everyone who studies computers knows this basic knowledge, and it is not advanced. It seems that these freshmen have just completed the public courses and have just started the professional courses.  The sound came from the classroom, and he picked up a few words casually. He didn't pay attention to it, and he was about to leave. But the teacher's words made him stop, and at the same time he raised his ears to listen carefully to the teaching content.  , the expression gradually became very strange, some were surprised, some were shocked, and some were happy, all kinds of expressions were intertwined, and there were mixed feelings. "It must be very troublesome for us to operate such a circuit, so we use some easy to remember.  The debit symbol standardizes some functional circuits and collections of functional circuits to facilitate our calling.  This is an instruction. When many instructions are put together, it is an instruction set.  Since computers were first developed by Westerners, in order to facilitate their research, memory, and use, of course, the debit symbol uses Western characters, that is, English as the command text.  At present, most of the instructions and instruction sets use English as the expression text.  The reason why we say it is the vast majority is because we have developed a processor that uses Chinese purely as instructions, called ¡®Actuarial Type 1¡¯!  This is the world's first processor completely developed for us Chinese, a pure Chinese environment processor with all intellectual property rights and patented technologies!  With this processor, we have for the first time got rid of the disadvantageous situation of relying on foreign processors as the computing core of computers, scientific instruments, automatic machine tools, vehicles, ships and aircraft. We are not afraid of being left with a secret door on the processor, and can safely and boldly  When used in the national economy, scientific research, entertainment, and military, you don¡¯t have to worry about being blocked or sanctioned by the enemy when you conflict with the enemy!  So, the invention of this processor is of great significance to us!  "The teacher is obviously very excited. His voice is getting louder, his speed is getting faster, and his tone is getting higher and higher. Even if he doesn't see it, Zhang Donglai can still imagine his high-spirited look. "The students are obviously too.  I was so excited when I heard the teacher's words. There was a burst of cheers in the classroom and excited conversations with his classmates. Zhang Donglai smiled and did not leave. He stopped outside the window and listened quietly.  Although this Chinese processor was not developed in China, at this moment, he was as proud and excited as the teachers and students inside. The teacher did not interfere with the excitement of the students!  , was quiet for a while, and then continued: "Let's talk about how to express Chinese instructions.  We said before that the words that drive the processor are only 1 and 0. When it is a single digit, it can only show two states: 0 and 1, that is, the upper limit is 2.  From this we can deduce that the upper limit of two-digit records is 2 raised to the power twice, which is four states.  When the digits are expanded to eight digits, which is 2 to the eighth power, the upper limit of the states that can be expressed is 256, and one state can determine an instruction.  In order to standardize character sets, early processors determined the ASCII character set based on Western cultural habits, so that all processors include this character set to accurately call English letters and other characters.  ??Here, Westerners have not considered the needs of users other than themselves. This is not difficult to understand. Western civilization is in its heyday. Strength and domineering are inevitable characteristics. It is natural to only consider themselves, regardless of the requirements of other races and civilizations.  Therefore, if you want to have a Chinese processor that meets the needs of our civilization, you can't get it by asking. This is why we need to independently develop a pure Chinese processor.  For the international standardization of text input, we also inherited the ASCII character set.  The Chinese instructions we have solidified in the processor are actually based on the modifications made to this character set. We use one hundred basic Chinese characters that constitute the instruction and replace the characters that we do not commonly use in order to achieve the one hundred basic Chinese characters.  Instruction call.  For example, to move a certain data, we use 'move' as the debit symbol for this instruction, but it still appears as a complete 'move xx to xx' when storing.  Okay, above we have a preliminary understanding of the implementation of Chinese instructions. Let¡¯s talk about how to call these Chinese instructions to meet our requirements.Control application of the processor.  Students have just learned how computers represent corresponding characters through different states. We can vividly think of this state, which is an eight-digit value, as the house number of a character, and one character corresponds to a house number.  When we call out a house number, we are calling this character.  A complete instruction is formed through different characters, and the processor is mobilized to work according to the instruction.  The same is true for Chinese processors.  We use a specific keyboard and only need to correspond to different instructions when entering the program, and the corresponding instructions can be called with one tap.  Let's use moving a certain data to illustrate. When we tap the corresponding key on the keyboard, 'Move xx to xx' will appear on the screen. The cursor will automatically stay on the previous xx. Directly enter the value or string and then press  The space bar or the Enter key will automatically jump to the next xx, so we enter the corresponding address code again to complete the data transfer.  ??You may feel uncomfortable at first, but it is just like practicing typing. Practice makes perfect, and you can master it with a little practice.  And because each time you only need to tap the keyboard to determine a command, it is easier and faster to say it than using a combination of English characters.  When changing from command to text input, we only need to click the switch key to use it as a normal text input tool.  "In the classroom, the students began to discuss excitedly again, and there were bursts of commotion inside. Zhang Donglai looked up at the ceiling, but he was thinking quickly based on what the teacher said, and quickly confirmed that this could indeed achieve Chinese  The command can be called quickly, and it is more convenient than the combined call of the English command! He couldn't help but feel depressed. Why didn't I think of such a simple idea? Jump to the next xx, so we entered the corresponding one again.  Address encoding completes the data transfer. You may feel uncomfortable at first, but it is just like practicing typing. Practice makes perfect, and you can master it with a little practice. And because you can confirm a command with just one keystroke each time.  It is simpler and faster than using English character combinations. When changing from instructions to text input, we only need to click the switch key to use it as a normal text input tool. ¡± In the classroom, the students started again.  As they discussed excitedly, there was a commotion inside.  Zhang Donglai looked up at the ceiling, but he was thinking quickly based on what the teacher said. He quickly confirmed that this could indeed realize the quick call of Chinese instructions, and it was more convenient than the combined call of English instructions!  He couldn't help but feel depressed.  Such a simple idea, why didn¡¯t I think of it?
