Chapter 6 MMX Instruction Set

The paper, entitled "A New Way of Using Computer Counting Manuscript Word Counts", was held in Hu Yiting's hand and looked at it carefully, only to see that it read:

“…… In order to help writers, editors, and other people in society who have word processing needs to improve the efficiency of word processing, accurately count the number of Chinese words and punctuation marks contained in the article, better grasp the quality of the manuscript, and improve the productivity of the socialist motherland, I have found a simple and fast way to use computers to count the number of words in the manuscript......

First of all, we enter the word or wps software under DOS, use the alt+F key combination, create a new wps or word text under the text jiàn menu, and then enter the document accurately, and then use the alt+T key combination, select the text tool menu, select the word count under the menu, we can find that the computer accurately counts the number of Chinese words and punctuation marks of the document for us......

…… The future of China is a China of science and technology, science and technology is the primary productive force, we junior high school students should study the great scientific and technological invention of the computer well, conscientiously grasp the various kinds of knowledge contained in it, be good at discovering the ingenious functions therein, and will certainly be able to make their due contributions to the four modernizations. ”

Hu Yiting patiently read it, restrained the ** who smacked a hundred feet, and said patiently: "Idiot, this is the computer paper you wrote?"

Zhang Baiqi saw that Hu Yiting's tone was not good, and asked a little nervously: "What's the matter? Can you pass Teacher Xie's level?"

"If he lacks a string in his head, Mr. Xie can let you pass. ”

"Did you say he was lacking?"

"I see you're lacking. ”

Zhang Baiqi was depressed when he heard this, scratched his head and complained: "Damn!

Sneering, Hu Yiting said: "Your thesis is like telling others that the back seat of a bicycle can be used to carry people and put things, isn't this pure nonsense?"

Zhang Baiqi shrugged his shoulders awkwardly and spread his hands: "It's no rut, I really don't have time to toss, it's horizontal and vertical." Tell me, this is about to take the high school entrance examination, how can I have time to do this?"

For students, the high school entrance examination is about the future. Hu Yiting nodded heavily when he heard this, and he didn't want his friends to delay their work for irrelevant things.

Zhang Baiqi suddenly had a whim, and said: "Slut, are you drawing this circuit diagram similar to a computer?" I said, you can even draw this thing, and you are quite familiar with computers?"

Hu Yiting prevaricated: "My dad and their newspaper have a computer, which is dedicated to text and picture processing and typesetting, I see that they have used it, so I know a little." ”

Zhang Baiqi slammed the table: "Then don't you know very well! Newspaper typesetting is a professional-level computer technology!"

"Tap!

Hu Yiting was startled by Zhang Baiqi's startle, looked up at the physics teacher, and saw that he was talking about a big question, and didn't notice that the two were talking.

Hu Yiting breathed a sigh of relief and pouted at Zhang Baichi, "Better than you." ”

"How much stronger than me?"

Hu Yiting was impatient: "Ten thousand times." ”

Hu Yiting is a serious doctor of microelectronics science and engineering, and computer science and technology, and when it comes to computer knowledge, it is really not bragging to say that he is 10,000 times more proficient than Zhang Baiqi, a three-legged cat.

Zhang Baiqi smiled, smiling like a thief.

He nodded heavily and said, "Okay, buddy, I'm in trouble!"

Hu Yiting's scalp was numb, and when he heard this, he felt that it must be no good thing.

"Slut, this paper is handed over to you, you write it, sign your name. When I went back, I went to explain to Mr. Xie of the Youth League Committee, and said that your father's unit has a computer, so your computer level is much better than mine!"

"How can I have such spare time? You have to prepare for the high school entrance examination, but I also have to take the high school entrance examination. ”

In fact, he was busy drawing, but he felt that there was not enough time, so he planned to refuse.

"Don't! brother is in trouble, you can't sit idly by!" Zhang Baiqi whispered urgently, and put his face up again.

"Brother Hu, Master Hu, Uncle Hu! I'll beg you, okay? Brother, you can't make me hand over such a nonsense thing and get scolded, right? Besides, if you have time to draw this ghost circuit diagram, can't you take the time to do me a favor?"

Hu Yiting smiled dumbly, he didn't expect that his own drawing would be regarded by Zhang Baiqi as evidence of leisure. said: "I can try, but I can declare first, write a paper that Mr. Xie can't understand, and you can fool around and pass the test, and there is absolutely no guarantee of winning the award." ”

Zhang Baiqi finally got rid of his troubles, and suddenly became happy: "It's none of my business to win the award or anything, it's your signature anyway." ”

Hu Yiting thought about it, if this is signed, it will be a shame for himself.

Zhang Baiqi took Hu Yiting's hand and said, "Slut, you are my own brother, as long as you can pass the level of Teacher Xie, let's find a food stall to celebrate." ”

Hu Yiting's goosebumps rose, and he quickly withdrew his hand and agreed with a wry smile.

Now that he was in a hurry to draw and prepare to review his junior high school textbooks, he thought that he would have to deal with the errand of this thesis.

didn't have time to think about it, just recalled the development of computer science around 95 in his mind, and Hu Yiting started writing.

He scribbled on the manuscript paper the title of the paper - "On the method of adding multimedia instruction set and floating point registers and corresponding functional components to the computer central processing unit (CPU) to enhance the multimedia processing power of the CPU".

Hu Yiting thought:

"INTEl didn't announce the MMX multimedia instruction set technology until March '96, and the Pentium MMX processor with the MMX instruction set was officially launched in January '97. At present, MMX technology is still in the verification stage in Haifa, Israel. ”

"Well, if I submit this paper, it's normal if I don't win the award, which means that the judges don't have this forward-looking vision and level. But at least, it's no problem to fool Teacher Xie of the Youth League Committee, you must not be able to understand it!"

As a full-stack siege lion of IC design, Hu Yiting always couldn't bypass the study of various instruction sets when he grew up, so his proficient program of MMX instruction set was no less than that of intel's engineers back then. As for knowledge such as algorithms, he is also familiar with it.

In order to be in a hurry, Hu Yiting hastily talked about the urgency of future computer multimedia applications at the beginning of the paper, and then went straight to the point, giving a complete introduction to the MMX instruction set that he claimed to have written himself, and then expounding the microelectronic components that need to be added to the CPU in order to support the MMX instruction set, and listing in detail the corresponding cup improvement design required to integrate microelectronic components with various functions, and expounding the mathematical logic of how to coordinate between the floating-point register and the processor segment address register, and explaining the working mode of assembly language calling the MMX instruction set。 Finally, the various technologies were explained in detail and in detail.

Good guy, this paper can't be put away when you move your pen.

Hu Yiting wrote until the end of school, and wrote ten sheets of A4 letterhead, but he didn't finish it.

"Damn! How did I come up with the idea to write about this topic? This is simply a large-scale systems engineering that involves too many things!"

"If it weren't for the fact that I have a super memory now, I wouldn't have been able to write all the sources of the citations and notes in this paper without looking up the information. ”

"If it weren't for this rebirth, with my memory in 2015, I wouldn't have been able to remember all the massive books and papers I had read in those years, let alone write so easily. ”

"But after all, this is too long, is it necessary to make such a long science and technology paper for middle school students? Who can read it?"

Hu Yiting wanted to give up and change the topic, but as soon as this thought moved, he secretly scolded himself in his heart.

"Isn't it just an MMX! Once reborn, I don't even dare to use this technology from 20 years ago, and I will talk about any ambitions in the future. ”

Thinking of this, he was ruthless, and decided to write this paper to the end, not for the award, not for anything else, just to fight for himself!

A paper was written before school was finished in the afternoon, and after school, Hu Yiting quickly packed his schoolbag, went out of the school gate with Zhang Baiqi and a few other good classmates, and immediately ran home.

As soon as Hu Yiting entered the house, he went into his bedroom and continued to write this paper about his own rivalry.

Papers should always cite from many books, technical materials, and papers of others, and should be noted.

If it weren't for his perverted memory, where would Hu Yiting remember the source of his views.

In this way, while rejoicing in his self-satisfaction, Hu Yiting felt that his rebirth this time seemed to have a power that he had not yet realized and could change the world.

When it was time for dinner, her mother Bai Ping knocked lightly on the door and pushed the door open: "Hu Yiting has eaten." ”

Hu Yiting hurriedly put away the paper, but fortunately, Bai Ping didn't pay attention, she thought her son was doing his homework.

Due to the busy work of dual-income families, the lunch at home is often relatively improvised, and the newspaper office is close to home. But in order to supplement Hu Yiting's nutrition, dinner is always done by his mother Bai Ping.

Stir-fried chicken gizzard with green peppers, roasted plum vegetables with pork belly, stir-fried chrysanthemum, and egg soup with tomatoes, each dish is delicate and delicious.

Hu Yiting almost burst into tears as he watched the sumptuous dinner.

"Mom, thank you. ”

Bai Ping was a little overwhelmed by her son's thanks.

Before that, her son had never said thank you to her for food, which is probably the common practice for all Chinese. Children feel that everything is natural, and few have said the word "thank you" to their parents, and most parents also feel that it is too obvious for the family to say thank you to each other.

"What do you say?" a smile appeared on Bai Ping's face.

"Mom, you're so tired from work every day, and you have to give me a table of delicious food, you've worked hard. ”

Hu Yiting felt that it must be a bit out of sight for the family to say thank you every day, but if they didn't say these two words over the years, they would be insensitive.

When Bai Ping heard this, she was already smiling from ear to ear, and she happily pulled her husband's sleeve.

"Yan'an, look, our son is sensible, and he knows that he feels sorry for his mother. ”

Hu Yanan was also a little surprised by his son's abnormality, he nodded to his wife and son with a soft face, and a smile appeared on his unsmiling face.

Hu Yiting remembered while picking up his meal that the last time the family ate together was in the second half of his sophomore year of high school, which was a casual meal, and his parents had parted ways legally since then, and he had become a lonely ghost.

Therefore, when faced with this rare reunion dinner, Hu Yiting almost shed tears. He forcibly held back his hot and churning heart, and took the bowl and picked up the rice vigorously.

"In this life, I must not follow the crowd like in my previous life, I can't let this family break up, I want to toss hard, and create a happier future for the family than in the previous life. If nothing else, just for these people who love me. ”
