Chapter 329: Let Them Fight

Guo Zhuocheng continued in the disgruntled eyes of the experts: "Let's imagine now, if the state does not give us salaries, if the scientific research results we have researched cannot win glory for the motherland, and if we cannot win honor for the university and our collective, will we study here for a long time?"

No! I believe that even if we love it, we will starve to death, and we will be scolded to death. Why scold? Because if we want to research, we have to consume a lot of financial and material resources of the country, and we will not be honored for such a big waste, who will starve if we don't starve? ”

After listening to Guo Shucheng's words, all the experts looked at each other: "fame and fortune" really disgusted them, but "honor and profit" made them not abandon.

Guo Shucheng's words made them shake their heads, and nodding their heads.

Wu Ying took a while before saying, "But we have no personal interests. It's not for personal honor......" However, she didn't have enough confidence to speak, and in the end, her gaze became wandering.

Guo Zhuocheng did not refute Wu Ying's words to embarrass her, but said: "The purpose of our computer development this time is to make profits, that is, to earn valuable foreign exchange so as to better serve the country." Since it is to make profits, since it is to make foreign exchange from abroad, what we are thinking about now is how to make more profits, how to make us earn profits for a longer time. Therefore, when we design a computer, we must always pay attention to a problem in our minds, that is, how to save costs, how to balance product performance and cost, and how to make a compromise between selecting components and keeping the product stable.

At the same time, we also have to consider the technical level and technical reserves of products in the future. An excellent enterprise, an enterprise that can earn huge profits for a long time, is not how much technology will be used in the product, but according to the needs and technical level of the current product users to select technology, will not be necessary to use the high technology reserves, to adopt the way of technological upgrading, upgrading and upgrading to gradually use.

In addition to making profits for a long time, this benefit can also keep pressure on competitors for a long time, so that they can always run behind us. If we foolishly use all the technology, our competitors will probably be defeated by our competitors as soon as they figure out our technology. ……”

As he spoke, Guo Zhuocheng firmly clung to the theme of earning profits for the country, and did a good job of eliminating everyone's rebellious mentality. As he spoke, Guo Zhuocheng himself felt that he was off topic, and he became a teacher teaching elementary school students, a teacher who was popularizing science to a group of people who didn't know anything, and even forgot about the computer standards he was going to discuss.

However, when it came to their eager and relish eyes, Guo Zhuocheng did not interrupt his lecture, and simply did not do anything, and said some of the commonplace and rotten competitive methods used by enterprises in his previous life:

For example, using overwhelming advertisements to promote products, such as applying for patents to protect their own technology, such as authorizing other manufacturers to produce in order to occupy the market as much as possible, such as recruiting agents from all over the world, such as entering the stock market in order to raise funds, and allowing others to buy company shares to obtain production and development funds...... What he said has nothing to do with technology at all, and is completely about the business operation of enterprises.

These things, which were known to almost everyone in the previous life, are a wonderful and colorful world in the eyes of these experts, in which they are like an ignorant child. They feel that every qiē is novel, and every qiē is incredible. Things in this world are completely different from what they used to think and think.

In the past, they never considered these in the development of products, they only pursued how to improve the energy of xing, only pursued high quality and high energy, only considered whether they could find high-standard accessories and components, and did not consider the cost, or would not spend too much effort to balance the relationship between energy and cost...... Fortunately, they are intellectuals, and they have a natural ability to accept new technologies, new ideas, and new ideas, and as long as they can be convinced, they can automatically adjust themselves, quickly identify with new knowledge and deepen it, and be able to draw inferences from others. Of course, Guo Zhuocheng's image in their minds has become even better.

After popularizing the science about the business behavior of enterprises, under Zhang Yunong's advice, Guo Zhuocheng's topic returned to technology. He led them to discuss the three aspects of computer architecture, cāo system, and main functions.

For the first aspect, that is, the architecture of the microprocessor, the first thing we encounter is the architecture of the microprocessor. Guo Zhuocheng said that he has followed the world's computer technology and believes that the current microprocessor architecture is mainly divided into two types: complex architecture and simplified architecture.

In the first computers, computers were basically complex architectures. A mathematical function, an access action, can all be classified as a single instruction; In order to meet the needs of users in different fields, various microprocessor companies simplify some actions, and then solidify them into instructions and write them into the internal circuitry of the processor. When the user writes the program, he can directly call the special instructions in the processor and combine them to realize the execution of the program.

With the development of technology, the needs of users are more and more complex, and the instructions superimposed on the processor are more and more and larger. Companies, domains, and users are trying to incorporate their own instructions into their processors to make them easier to use.

The expansion of the scope of computer application has accelerated the rapid proliferation of this behavior. Each new instruction has to be designed with a dedicated circuit, and the processor gradually begins to become overwhelmed by the rapid accumulation of new instructions.

On the one hand, the microprocessor can't withstand too much instruction accumulation, and the running speed is greatly deteriorated, and on the other hand, many of the instructions in it are not used by users at all, and each user can only use a small part of them. In many cases, 0% of the microprocessor's operations are actually done by 20% of the circuitry. This also means that 0% of the circuitry in a processor is idle most of the time and is only called in rare cases.

A large number of idle circuits are always in a charging state, and the consumption of energy, the heat emitted by the circuit, and the interference to adjacent circuits reduce the computing efficiency of the processor.

As a result, some people began to drastically cut down the already bloated instructions, and only a dozen of the core instructions were enough to complete the basic operations, and the rest of the instructions were implemented through guò software, so that the computer could use it to the highest efficiency. Because of the waste of resources caused by ineffective commands, many people have come to identify with this microprocessor architecture, but some people are obsessed with microprocessors with complex architectures.

Guo Shucheng, who tasted the sweetness of the controversy, continued to lead the debate: "Now please express the method, which microprocessor architecture should be adopted in the computer we developed? ”

Sure enough, as he expected, when it came to determining the microprocessor that would be developed for the computer, the microprocessors of both architectures had their own supporters, and they began to quarrel as soon as they had just listened carefully to Guo Zhuocheng's analysis.

Wang Mulang said clearly: "I advocate the use of the previous microprocessor. The so-called simplified and complex types are artificially defined by you, and you impose a derogatory word on the original microprocessor - complex. I think the original microprocessor should be defined in terms of comprehensive, stable, mature, and so on.

Now the international common is what you call the complex architecture type, the technology is very mature, and many instructions can be called, why do you have to use software to implement it? If there are too many instructions, we can use very little, which will inevitably cause hardware waste, which is a shortcoming that cannot be concealed, but compared with software to solve these problems, it is easier to call, more reliable to operate, and more stable. Coupled with the fact that we are developing a home computer, the waste of some of the hardware of the microprocessor is not a big problem. Think about it, how much xing energy can a family use? How is it possible to use all microprocessors?

On the contrary, if we are to be different, we must use the simplified architecture that has just begun to appear, and it remains to be seen whether it will be recognized by the market. Complex architectures have matured, and there is no mature standard for how simple to reduce instructions, and long-term research is needed to draw conclusions. If we lose the first battle, not only will our own faith be dealt a heavy blow, but it will also leave a bad impression in the minds of the world. ”

Zhang Yunong said: "I agree with Professor Wang's opinion. We are developing a brand new computer, a qiē should be safe, first make the product, run for a period of time, find the advantages and disadvantages of the adjustment, accumulate experience and then step by step. I think that most of the complex structures in the world are now adopted, and this must have its own reasons for existence, and it is certainly not out of thin air, let alone a visitor from outside the world. ”

This time, Wu Ying raised an objection, saying: "I have adopted a simplified structure, which is in line with the cháo flow of technological development. We can't solidify an instruction in it just by adding a function, especially with the large-scale popularization of computers, the relevant solidification instructions must increase exponentially, and the hardware of the microprocessor simply cannot keep up with this growth.

In addition, there are many different industries, and instructions in one industry may not be useful in another, which will inevitably lead to more wasted instructions, and hardware will always lag behind the needs of fixed instructions. On the one hand, the waste of circuits in microprocessors is increasing, and on the other hand, there is more and more demand for circuits in microprocessors, which will inevitably cause the price ratio of microprocessors to be lower and lower.

However, with a simplified architecture, there is no such contradiction, and the microprocessor can meet the requirements with little or no forced change. As for the use of home computers in the home, it is impossible to make full use of the microprocessor's xing energy, which is of course the reason for the microprocessor to adopt a complex architecture, and it is also a reason to adopt a simplified architecture, precisely because the home computer needs not many instructions and few functions to call, which means that the software is easy to solve these problems. ”
