Ling Shizhe received a notice from the secretariat at noon that Professor Wang Haihua of the Department of Electronics of the University of Hong Kong, Dr. Xu, President of the University of Hong Kong, and Dr. Xu Hongbo, President of the Hong Kong Polytechnic University, were going to visit him at 14 o'clock this afternoon.

Hearing the secretary's notice, Ling Shizhe originally planned to think about Ling Zhigao's report on the real estate development plan of his eldest brother and others in the afternoon, but now he can only change the day. I don't know what they are doing this time, but I think there are ten new process design obstacles.

At 14 o'clock, the three of them arrived on time, and after the three shook hands with Ling Shizhe, Xu Hongbo, president of the Polytechnic University, said: "Ling Shao, we come to your company this time first of all to thank you for allowing us to participate in the upgrading and transformation of semiconductor chip factory equipment in Canada. ”

"Ah, there, the three professors are so angry, I don't need to thank you, on the contrary, I want to thank you, if it weren't for the help of the University of Hong Kong and the Hong Kong Polytechnic University, our company would not have been able to upgrade all the factories before the end of the year. I should be the one who wants to say thank you. Ling Shizhe responded with a smile.

Dr. said in English: "Mr. Ling, I really want to thank you this time, you must know that semiconductor technology is an emerging industry, and its future is extremely bright. The world's most advanced semiconductor technology is in Silicon Valley, especially in Sfortin University, where she has cultivated many outstanding computer talents for the United States. Hong Kong has always wanted to train outstanding computer talents for Hong Kong, but unfortunately, Hong Kong's industrial level is too low, which greatly restricts the development of Hong Kong's computer technology. As an absolute authority in the field of semiconductor chips, Mr. Ling invented the world's first CPU, which won glory for Hong Kong and changed the future of Hong Kong. ”

"Hmm...... I don't have the ability to change the future of Hong Kong, Robinson is serious. Ling Shizhe was taken aback, damn, inventing a CPU changed the future of Hong Kong, what kind of logic is this, it makes me too high, this is simply a killing, refuse, it seems that they prepared a big hole for me this time.

Wang Haihua has made friends with Ling Shizhe many times, and he knows Ling Shizhe very well, the more you praise him, he will think that you are killing him with bad intentions.

This is not to say that Ling Shizhe can't listen to praise, he is also a human being, how can he not like to listen to the words of praise, but too much experience in his previous life tells him that the more others praise you, the more it means that there is a conspiracy, in this regard, he suffered too much loss in his previous life, and in the back, such a murder conspiracy simply made him unguardable, and even once heard someone else's praise, he didn't say anything, there was no expression on his face and any expression, the boss said that he was proud and complacent because he thought he had made a little achievement, The enjoyment of these praises was comforting, and since then he has been thrown into the cold palace, and it didn't take long for him to be kicked out of the company.

Many years later, he learned that it was a trap given to him by the boss back then, thinking that he was useless and unnecessary, and it was a typical crossing the river and demolishing the bridge. Humbly refuse, they say that you are hypocritical, untrustworthy, and you have been beaten into the cold palace and kicked out again. In short, no matter how you deal with it, it's a set, all kinds of tricks are waiting for you, and you can't turn it over.

Looking at his expression, Wang Haihua knew that he was on guard, Wang Haihua didn't want him to misunderstand, so he interjected: "Ling Shao, what Professor Dr. said is true, we are sincerely grateful to you, especially when you handed over the new process production line of semiconductor chips to us to participate in the design, but for our Hong Kong universities in the past two years, we have cultivated many outstanding talents, we hope to continue to cooperate with you, or in-depth cooperation." ”

"The integration of production, education and research is a common phenomenon in western developed countries, but Hong Kong is still very weak in this regard, and there are few factories in Hong Kong that engage in industry-university-research cooperation with us, and those factories have no technical content at all. We have negotiated, our two schools plan to combine their respective advantages, cooperate to set up an electronic computer college, specializing in computer technology, semiconductor chip technology and software technology personnel training, yesterday has obtained the consent of the Hong Kong government, in the future Ling Shao does not need to worry about not being able to recruit suitable talents. Xu Hongbo added.

Ling Shizhe's eyes lit up and said, "This is a good thing, I originally planned to set up a semiconductor chip laboratory in Canada and Hong Kong. Canada is the RISC lab, Hong Kong is the CISC lab, but because there are not many talents in semiconductor chip technology in Hong Kong, the Hong Kong lab is still an empty shell since its establishment, and now the Hong Kong government has agreed to establish a computer school to relieve one of my worries. ”

"Oh, Ling Shao is a CISC laboratory in Hong Kong? Earlier, I read Ling Shao's article, Ling Shao divided the CPU into two types: RISC and CISC, RISC I know, the chips used in the computer cameras and scientific function calculators on the market are RISC, and what is the CISC used for? Dr. came from a background in economics and was not proficient in electronic semiconductors.

"Haha, Professor Robinson, this is simple, RISC refers to reduced instruction set computer, which is generally used in special professional fields, such as computer cameras, word processors of Wang An's company, scientific function calculators, etc., all of which belong to the RISC category; CISC refers to a complex instruction set computer, which is also known as a general-purpose computer, which is generally used on personal computers. Ling Shizhe said.

"Pcs? Ling Shao's computers are so expensive now, unless people are very rich and love computers like crazy, they will buy them, and now those computers are not used by enterprises and institutions. I can't imagine a personal computer, with my current income, I can't afford to buy one even if I don't eat or drink for ten years, forget about the personal computer, I don't know when it will be realized? I'm saying that people buy a computer for what they do, like my family, they can't use it at all, even if they use it for family finances, an ordinary calculator is enough, not even a function calculator, computer, I really don't know what use it will be for me. Xu Hongbo said with emotion.

Xu Hongbo's words attracted the approval of the other two.

Indeed, in terms of practical use alone, there is indeed no need for individuals to buy computers, and the lives of ordinary people are the household expenses of firewood, rice, oil, salt, sauce, and coarse tea, which can be solved with an ordinary calculator. But the market has become an indispensable part of people's lives like household appliances, the reason is that one is the network, the other is entertainment, the future computer is a tool for people's entertainment, and the price will become very cheap, as long as you don't have a harsh pursuit of the computer, it is even cheaper than some household appliances.

But how do you tell them that the biggest use of personal computers is for playing video games, watching movies, watching TV, surfing the Internet and other entertainment? If you say that, the three old gentlemen who have been teaching and educating people all their lives will definitely go berserk.

Using such expensive equipment as a computer to watch movies, television, and play games is purely a plaything in the eyes of these old pedants. Watching movies, don't you go to the cinema, watching TV, you don't use the TV at home to watch it, use the computer to watch it? You are a local tyrant, you have money, and no matter how local tyrant you are, there is no such tyrant law. Even if you have the money and you can afford it, many families can't afford it, so who will sell this person's computer to?

This kind of problem is no longer a simple problem of ideology and concepts, but a problem of the limitations of the times. No one in this era would have thought that 40 years later, computers would become one of the household appliances in people's daily life, just like televisions, refrigerators, and air conditioners.

Obviously, I can't explain to them in this aspect, I can only start from other aspects, and after thinking about it, Ling Shizhe decided to start from Moore's Law to explain this problem.

Ling Shizhe thought of his words and explained to them: "Dr. Xu, in fact, from the invention of the first generation of electronic computers to the present, we can find a law: and the size of computers is getting smaller and smaller, the performance is getting more and more powerful, and the price is getting lower and lower. Think about what he could do when the first tube computer came along, and what was the price? When IBM made the first mainframe, how much did it cost? What was the price of the world's first medium-sized machine when it appeared, and what was its price when DEC invented the world's first minicomputer? From here we can see that the price of computers is falling every year, the volume is gradually shrinking, I believe that it will not be long at most a few years, the computer will become small, the performance is powerful enough, and the price will be reduced to the range that every family can accept, and it will be cheaper and cheaper, it will definitely enter the family, I am full of confidence in this. ”

Wang Haihua thought for a while and said: "Ling Shao is right, the current computer is this development trend, the size is getting smaller and smaller, the price is getting cheaper and cheaper, and the performance is getting stronger and stronger. ”

"Okay, I admit that what Ling Shao said makes a lot of sense, but why can personal computers only use CISC complex instruction set processors, but not RISC reduced instruction set processors?" Xu Hongbo raised another question, he was born to be mechanical, and he didn't understand computers, and only Wang Haihua was an expert in semiconductors among the three, but he didn't understand why personal computers could only use complex instruction set processors and not reduced instruction set processors. He also wanted to hear what Ling Shizhe would say, and the three of them looked at him in unison.

Ling Shizhe looked at the three of them and saw that he couldn't explain it for a while, could it be said that this was proved by the history of later generations, and the personal computers in the history of later generations used CISC complex instruction set processors? In this way, the three of them will definitely treat him as a psychopath.

After thinking about it, I decided that it would be easier to understand them from the perspective of general-purpose computers.
