"What happened? Did the old thing stink?" Cao Changjiu was looking forward to a happy ending.

"Of course it stinks, but the old thing stinks and doesn't fall, it becomes more and more shameless, and finally it is treated coldly in the academic world, and it is over. As soon as this matter was discovered, all the professors were in danger, regarded me as a heretic, and made it difficult for me to defend my dissertation. ”

"Then you're not very dangerous, it's not easy to find a leak for this kind of thing?

"That's natural, I offended them, can I have good fruit to eat? Later, it ended up like this, but fortunately, Lao Tzu is officially compiled, and they can't squeeze me away if it's right. Now the bonus benefits don't have my share, how easy is it for me to go, Lao Tzu prefers to spend with them, to see who dies first. Although he said it ruthlessly, the lonely look on Kaohsiung's face was nothing to hide.

"I'll tell you the truth, high-achieving students, do you really want to study Dream of Red Mansions for the rest of your life?" Cao Changjiu felt that it was necessary to enlighten and enlighten him, so as to save another problem character in the future, "You are all seniors in this field, and you can't get ahead if you are less than seventy or eighty." Although red science is also an art, it feeds a large number of old things. But don't you feel bored? Don't you think it makes more sense to do something else with a copy of the Red Mansion in your hand and digging out your mind to find some conjectures that you don't know?"

"I want to, too, but I just can't swallow it, and I want to prove that I can do better than them in this field. Kaohsiung's defense was a little weak, and he was also asking himself if it was worth it?

"I admit that you can definitely make a difference, I am an engineer, and I don't know much about your academic research, but the spirit of science is universal, bold assumptions, careful argumentation, this is the famous words of the leader. Now we assume that you have achieved results, not small, the first in the world, no one can surpass you, the first person in the past. ”

"But what can be done, the leader of Red Studies? If you can't escape the word bookworm, what is the benefit of the country and the people, and what is the benefit of yourself? Studying these classics is the patent of those old men to eat, and if you rob them of their jobs, can they not be anxious with you? You just let them go, don't fight with them, not to mention the pseudo-classics of the Red Mansion, but it's just a novel, and it's a bit crazy to artificially raise it to the point of discussing the past and the present, let alone being a eunuch?"

"What eunuch?" Kaohsiung was a little puzzled by the long-standing neologism.

Chang Chang had no choice but to explain: "What is under the eunuch?"

"There is no eunuch below!" this Kaohsiung understood as soon as he heard it, fully exposing his ** nature.

"That's it, why did my Cao family come up with such a thing, I didn't finish writing the book, it seems normal, but it's missing, it's not a eunuch. ”

"That's it, haha. As soon as Kaohsiung said this, his emotions were obviously high.

Cao Changjiu struck while the iron was hot: "You said that such a worthless thing is nothing to study, take advantage of the good time of your youth, or do some promising work." ”

Kaohsiung hesitated: "But I'm a student of Chinese, what else can I do if I don't do this." ”

"Stupid, writing novels, writing scripts, engaging in literary criticism, and being an editor, what kind of thing can not make money to support your family and go down in history? If you have greater ambitions, you can also do a study on the development and future of Chinese society, and you can also gain fame and fortune, wouldn't it be happy? Cao Chang agitated like a spring's tongue, slamming into Kaohsiung's stagnant heart.

"Novels and scripts are okay, and you let me do state studies in the Chinese department is too seasome." "Kaohsiung is a little overwhelmed by the breadth of Cao Changchang's thinking.

"The insight of the world is all knowledge, and the practice of human feelings is the article. Who said that those who study Chinese cannot participate in the formulation of national policies? The world will be ruled in chaos for a long time, and now is the time when the new leading body has come to power, and in the era of stability after the turmoil, the national strength will inevitably grow by leaps and bounds. Studying the trend of the country is the most promising work, which is beneficial to the healthy and rapid development of the country and contributes to its own strength. Second, they can recognize the situation clearly, conform to the general trend of the world, and individuals can live a better life, whether it is spiritual or material. Besides, can you bear to let China advance under the guidance of a bunch of foreign experts and foreign theories? If in the future, everyone learns English, Chinese declines, the national policy is controlled by compradors, and the land of China becomes a colony of the great powers, how can I have the face to meet the leader under the nine springs?" Cao Changjiu also drank a lot of wine, and he was a little leaky under his impassionedness, and hurriedly observed Kaohsiung's reaction.

Fortunately, Kaohsiung, who was drunk and brainy, was gritting his teeth with enthusiasm and indignation, as if he had not heard the flaws in his long-term words, "We must not do this to defeat imperialism!"

"Well, well, the country and the people will remember you, think about how you should go. Now the country and the people need you to go back, wash and sleep!"

After Cao Changjiu woke up the next day, he felt a splitting headache, and he was lazy and didn't want to move, so he lay in bed for a day before he felt a little better. By the time he arrived at the computing office, it was already the third day.

After two days of not seeing each other, the 757 prototype had been inspected and various tests began.

The new compiler has undergone prototype tests, and the compiled program gives full play to the characteristics of the vector machine, and the measured results are several times faster than the old one, and the performance indicators of the machine have been improved by several grades.

As for why the results of the two tests of the long-term compiler are so different, it has to start with the technical school of computers.

In the early days, computers were not out of the category of calculators due to their weak computing power and few functions. The pioneers did everything possible to improve the hardware and add a variety of instruction enhancement functions, so that the computer became more and more powerful, and the number of instructions also proliferated.

Originally, this was nothing, and the increase in instructions did improve the performance of the machine, and it also made it easier to write software. It wasn't until the birth of IBM 360 computing that the concept of compatibility broke the equilibrium.

Under the pressure of compatibility, companies have to keep the instructions of the previous generation of computers when designing the new generation of computers, and add new instructions on top of them.

Passed down from generation to generation, the instruction sets of computers became bloated and complex, forming a genre called Complex Instruction Set Computers (CISC).

CISC has many instructions, up to more than 800 instructions, which originated from the early idea of people wanting to make hardware software.

At that time, hardware was cheap to manufacture, and software was becoming more and more expensive, which eventually led to the software crisis. People dream of building a machine that can recognize and run high-level languages without barriers.

Therefore, people continue to add instructions to the computer, and the benefits are obvious, the software compilation becomes simpler, and the whole 60s and 70s are the world of CISC.

CISC solves the software crisis, but it doesn't expect it to become another monster.

The existence of a large number of instructions greatly increases the hardware complexity of the system, and it is necessary to know that one more instruction requires one more pair of control logic.

The hardware overhead was too high, and eventually it exceeded the limits of technology at the time, and the hardware cost was unattainable.

When you are poor, you think about change, and people of insight begin to reflect on whether this path is wrong.

Just as the concept of compatibility was proposed, it was IBM that led the way, proposing the famous 80/20 rule, that is, 20% of instructions are used more than 80%, while the other 80% of instructions are only 20% used.

Based on this principle, the Grandmasters came up with the concept of Reduced Instruction Set Computer (RISC).
