Chapter 17: FPGA electronic board

Views:

At 7:40 the next morning, Jiang Yubai walked into the office of his homeroom teacher, Mr. Wu, with a letter of apology.

Coincidentally, Wei Rongjie and Liu Xingjian also arrived.

Jiang Yubai, Wei Rongjie and Liu Xingjian lined up and stood obediently in front of the head teacher.

Teacher Wu accepted the three people's self-criticisms and read them on the spot. Her eyebrows were furrowed more and more, and her facial expression became solemn.

Jiang Yubai was a little nervous. Last night, he copied the self-criticism by hand. He kept Lin Zhixia's manuscript at home, and then gave his copy to Teacher Wu.

There is no doubt that Lin Zhixia's writing style is very obvious. Her vocabulary is very rich, and her ability to choose words and construct sentences is unique.

In comparison, Jiang Yubai's Chinese language level still has a lot of room for improvement. Jiang Yubai suspected that Teacher Wu would find out that the self-criticism was actually written by Lin Zhixia.

Teacher Wu has been teaching for many years and has a keen eye.

She is the head teacher of a key class in the provincial experimental primary school. She has taught many students and must be very familiar with the little tricks of primary school students.

Jiang Yubai began to think, if Teacher Wu saw through the truth, how should he explain himself so as not to implicate Lin Zhixia.

Before he could figure out what was going on, Teacher Wu suddenly said, "Liu Xingjian, Wei Rongjie, did you two write your self-criticism seriously yesterday? It was an 800-word self-criticism, but it was all the same words over and over again. What do you two mean by this? Your attitude is very improper."

Liu Xingjian looked pale and seemed to be hesitant to speak.

Wei Rongjie stammered, "Teacher Wu... I, I can't write it..."

He sniffed and sniffed quietly.

Jiang Yubai felt some sympathy for Wei Rongjie.

Yesterday morning, Jiang Yubai had to think hard and torment himself before he could come up with 13 words.

Without Lin Zhixia's help, Jiang Yubai would not be able to write an 800-word self-review even if he stayed up all night.

Why

It may be because Jiang Yubai subconsciously did not think that he had made a huge mistake. Drawing comics and playing games with his classmates was not an unforgivable thing. Lin Zhixia also let the whole class see the strangeness of the world, the beauty of physics, the mysterious charm of astronomy, and the importance of economic models.

Jiang Yubai nodded. Yes, his self-examination was only forced by the situation. He still had a desire to learn "Exploring the Universe".

"Jiang Yubai," Teacher Wu praised him at this time, "Your self-criticism is well written. Teacher Wu can feel that you are truly regretful, know your mistakes, and have corrected your attitude."

Teacher Wu handed Jiang Yubai's self-criticism to Liu Xingjian: "You should learn from Jiang Yubai's good quality of correcting mistakes. I criticize you for your own good. If I ignore you, that would harm you. Liu Xingjian, Wei Rongjie, hand me another 800-word self-criticism before 8 o'clock tomorrow morning. Correct your attitude, okay? Don't let me see repeated sentences, and don't write a sentence over and over again ten times. That's just perfunctory, and you don't correctly recognize your shortcomings."

Liu Xingjian and Wei Rongjie could only agree obediently.

After leaving the office, Wei Rongjie quickly caught up with Jiang Yubai and asked, "Jiang Yubai, why did you write such a good self-review? You didn't drag other students into the water, nor did you say bad things about others..."

Jiang Yubai replied: "The self-criticism is for myself, I won't involve others."

"Jiang Yubai," Liu Xingjian suddenly called him, "Stop right there!"

Jiang Yubai ran into the classroom. His sports coat was slightly open, and he ran like a knight. He threw a sentence to Liu Xingjian: "Why should I listen to you?"

Liu Xingjian was angered by him again.

Liu Xingjian originally wanted to condescend and personally ask for advice on how to write a good self-criticism - this was Jiang Yubai's only chance to please Liu Xingjian.

If Jiang Yubai tutors him patiently and behaves politely enough, Liu Xingjian will forgive Jiang Yubai and all the mistakes he has made before.

However, unfortunately, Jiang Yubai wasted this precious opportunity.

Liu Xingjian punched the main door of the classroom and said sinisterly, "Jiang Yubai! Just wait for me!"

As soon as these words were spoken, the whole class couldn't help but look at Jiang Yubai.

Jiang Yubai completely ignored Liu Xingjian. He could not wait to return to his seat and report the good news to Lin Zhixia: "Teacher Wu accepted the self-review. She did not ask me to rewrite it."

Lin Zhixia was calm: "That's great."

Jiang Yubai opened his schoolbag and took out a book called "Mathematics for Grade 4, Volume 1" which he would use for the next class.

He pretended to be reading a math book. He thought for a while, sitting upright, and said sincerely and formally: "Lin Zhixia, thank you for your help."

"What did you say?" Lin Zhixia put her hand next to her ear, "I didn't hear you."

Jiang Yubai sneered: "Forget it if you didn't hear it."

Lin Zhixia imitated him and sneered: "Hahahaha, Jiang Yubai, are you shy?"

Jiang Yubai was not shy at first, but when Lin Zhixia asked him this, he felt a little embarrassed. He changed his sitting position, facing the other direction, farther away from Lin Zhixia.

Lin Zhixia called him: "Jiang Jiang Jiang Jiang Yu Bai!"

Jiang Yubai immediately responded: "Linlinlinlinzhixia!"

Lin Zhixia said, "Eh?" "I thought you would say, lunatic."

Jiang Yubai insisted: "These three words are a bit offensive. If you want me to say it, I will not say it."

The two of them were bickering when the voice of the dean suddenly came over the school radio.

The dean asked the fourth-grade monitor and deputy monitor to go to the printing room immediately to pick up an important document. The head teachers of each class must also coordinate their recent work.

The dean announced on the radio: "Adhering to the principle of voluntariness, students in each class should inform their parents and make their own choice whether to get the hepatitis B vaccine."

Hepatitis B vaccine!

Hearing these four words, Lin Zhixia's face turned pale.

She is most afraid of injections!

As soon as she saw the needle, she would be terrified. The truth of the universe, Nietzsche's hypothesis, and the second string theory would all be thrown out of her mind. That sharp and sharp needle was the whole world she saw in her eyes - of course, that world was gloomy, dark and gloomy.

Where is Jiang Yubai

Is Jiang Yubai afraid of injections

Lin Zhixia suddenly turned her head and stared at Jiang Yubai without saying a word.

Jiang Yubai felt uneasy when she stared at him, and couldn't help asking, "What's wrong with you?"

Lin Zhixia blinked her eyelashes twice. How could she tell Jiang Yubai how much she hated injections

In the comic book series "Exploring the Universe", Jiang Yubai portrayed Lin Zhixia as "the God of Truth, the First Military Advisor, and the Space Navigator". These unusual titles brought a bit of idol baggage to Lin Zhixia. She was ashamed to admit that she would cry when she saw a needle.

As a space navigator, the first military strategist on Earth, and the God of Truth of the Orion Base, Lin Zhixia is not strong at all. A mere hepatitis B vaccine can make her feel dangerous.

But if Jiang Yubai was also afraid of injections, Lin Zhixia would be able to gain his empathy. Lin Zhixia asked in a roundabout way: "Jiang Yubai, did you hear the broadcast just now?"

Jiang Yubai said calmly: "I heard it."

"What do you think?" Lin Zhixia tested him cautiously.

"I don't have any feelings," Jiang Yubai took off the cap of his fountain pen and started writing a math homework assigned by his tutor. "I got the hepatitis B vaccine last year."

So, this time, Jiang Yubai doesn’t need to be vaccinated again

Lin Zhixia envied him so much.

She asked bluntly, "Do you cry when you get an injection?"

"Why are you crying?" Jiang Yubai was confused. "Just bear with it for a while and it will be over."

Lin Zhixia's questions ended here. She was sure that Jiang Yubai didn't care about the "injection" at all. She was like a downtrodden soldier who had lost his allies, and she spent the whole day in a daze.

But she still has a glimmer of hope - the hepatitis B vaccine is not free. Not only is it not free, it is also quite expensive.

The monitor and the deputy monitor went to the printing room to get the hepatitis B vaccine brochure. The monitor distributed this batch of brochures to every student. On the brochure, it was clearly written in black and white: Our school cooperates with the provincial tertiary hospitals to ensure the safety, reliability, effectiveness and stability of the hepatitis B vaccine. The hepatitis B vaccine costs 72 yuan per person, and 24 yuan per dose...

After reading this, Lin Zhixia had an idea.

Yes, she knew that the hepatitis B vaccine needed to be given at least three times.

24 yuan for one time, 72 yuan for three times.

Indeed, 3 times 24 equals 72.

However, last time when we had to pay 76 yuan for the autumn outing, my mother was reluctant to let us spend the money.

My mother will definitely not want to accept the hepatitis B vaccine which costs 72 yuan this time!

If mom doesn’t give her money, Lin Zhixia won’t have to get the injection!

That evening, the setting sun shone brightly on the earth, and the cold wind of late autumn was mixed with a chill.

Lin Zhixia rushed into the house carrying her schoolbag and confidently handed the "Hepatitis B Vaccine Brochure" to her mother.

She behaved very well and quietly, just waiting for her mother to say: "Xia Xia, there is no money at home. Can we not get this 72 yuan vaccine?"

She can happily answer: "Okay, Mom." Xia Xia doesn't want to get an injection.

However, however, the opposite happened.

Mom carefully read the "Hepatitis B Vaccine Brochure" and loudly called Lin Zhixia's father.

Dad and Mom discussed it for a while, and Dad suggested, "Xia Xia got a hepatitis B vaccine when she was born. She's 9 years old now, and the brochure says that the antibody titer will weaken year by year. Why don't we get her vaccinated again?"

Mom agreed readily: "Okay, let her go to school. We can trust the doctors at a tertiary hospital. We will take Xia Xia back to our hometown for the New Year next year. There are not many elderly people in the countryside who like to be particular. With so many people coming and going in the family, we need to make some preparations in advance."

"I haven't been back home for a year," Dad sighed, "My parents said on the phone that they want to see Qiuqiu and Xiaxia..."

My mother sneered, "Come on. Your mother has been partial to her for a long time. She only has her grandson in her eyes, not her granddaughter."

"Don't talk to me like that in front of the children," Dad pointed at Lin Zhixia.

The mother opened the money box, took out 72 yuan and gave it to Lin Zhixia. The mother also coaxed her: "Xia Xia, you are 9 years old this year, you are a little adult, you can't be afraid of injections anymore. Vaccination is a good thing, you must know more than mom, mom won't say more."

Lin Zhixia looked dumbfounded. She took the 72 yuan in silence and walked slowly towards her bedroom.

She recalled the experience of getting an injection when she was a child, as if she was experiencing the scene all over again. She wrapped the 72 yuan in a handkerchief, tied a knot, and then stuffed the handkerchief into her schoolbag.

The night sky is vast, the evening breeze is gentle, and the faint moonlight shines through the glass windows, but is completely blocked by the bright lights inside the room.

Lin Zhixia held her rice bowl, sat at a round table, and ate dinner quietly.

The TV was playing "Big Windmill". Tonight's program was the animated version of "Journey to the West". Sun Wukong held the golden hoop, leaped into the air, swung the stick, and chopped the White Bone Demon into ashes on the spot. How majestic!

Lin Zeqiu cheered: "Well done!"

He turned his head and looked at his sister: "Lin Zhixia, what's wrong with you? You're so listless while eating."

Mom picked up a chicken wing for Lin Zhixia: "Xia Xia, what are you thinking about?"

Lin Zhixia held the chicken wing in her mouth but didn't respond.

Tonight's chicken wings are braised chicken wings carefully cooked by my mother. The meat is tender and delicious, and the heat is just right. While eating, Lin Zhixia thought, how many good days like today can she have before she gets the hepatitis B vaccine

His sister's abnormal behavior caught Lin Zeqiu's attention.

Lin Zeqiu put down his bowl, leaned forward slightly, got close to Lin Zhixia's ear, and shouted, "Hey! Lin Zhixia!"

Lin Zhixia was frightened out of her wits by him.

My mother was so angry that she scolded, "Lin Zeqiu, what's wrong with you? Why are you scaring your sister like that? You are her brother, but you don't behave like a brother at all!"

Lin Zeqiu was eating his meal. After taking two bites, he said, "I see she is always in a daze..."

Lin Zhixia refused to admit it: "I wasn't in a daze!" She held the chopsticks and poke the rice in the bowl: "I was just thinking about the vaccination."

"You are nine years old, and you are still afraid of injections?" Her brother mocked her mercilessly, "Girls are just delicate. When I was seven years old, I got into a fight and my knee was cut, but I didn't make a sound."

Lin Zhixia sneered: "When you were seven years old, you wet the bed once."

She described the situation in detail: "When mom and dad took us back to our hometown, you didn't dare to use the toilet in the countryside. You were afraid of bugs in the dry toilet. Boys are really brave... My brother is so brave, but he would panic when he saw a bug."

Lin Zeqiu was hit in the sore spot and fought back fiercely: "When you were seven years old, how were you better than me? You were afraid of the dark, ghosts, and aliens, and you always asked your mother to go to your bedroom to coax you to sleep. I have never seen a girl more timid and cowardly than you!"

"So what!" Lin Zhixia's face suddenly turned blue and red, "Mom likes me, and she is willing to coax me! My brother always quarrels with me, and it is even more impossible for Mom to coax you!"

Lin Zeqiu slammed the bowl on the table: "Do you think everyone is like you? I don't care!"

Lin Zhixia stared at his expression and said, "No, I can see that you envy me."

Mom patted Lin Zhixia's shoulder and said, "Xia Xia, stop talking and eat quietly. The food is getting cold."

Then, the mother turned around and warned her brother: "Lin Zeqiu, don't make trouble at the dinner table. Let your sister finish her meal. She is only nine years old this year, and you are three years older than her. Can't you give in to her a little? You have to fight with her for everything! Your sister is so young and thin, how can she not eat well?"

Lin Zeqiu uttered a dull "hmm".

The indoor light shone on him, his short hair was a little messy, hiding the emotions in his eyes and eyebrows. He maintained a restrained silence and ate without making any sound.

Lin Zhixia stared at his profile. After a moment, she secretly picked up the largest chicken wing, put it in Lin Zeqiu's bowl, and poured some soup on him with a spoon.

He started making sarcastic remarks again: "Who wants your chicken wings?"

His mother glared at him, and he changed his words dryly: "It's delicious."

After dinner, Lin Zeqiu was washing dishes in the kitchen while Lin Zhixia was reading a book in the bedroom.

On Lin Zhixia's desk is a book called Puter System Architecture. She borrowed this book from the provincial library. It was published in 2003 and is very popular. Many people line up for it.

Lin Zhixia had been waiting, and it was finally her turn the day before yesterday. The librarian called the Lin family as a notification, and Lin Zhixia went to the provincial library that day and brought the book home.

Last night, she found time to read most of it, and this morning, she had basically finished the whole book.

This book mainly describes the computer system architecture. Lin Zhixia has been studying this topic recently. She really wants to make PCB components, design circuits, operate FPGA electronic boards, and make a computer CPU by herself.

Her idea was wonderful, but the reality was cruel. In order to fulfill this wish, first of all, she must have money. Secondly, she should have a workshop. The above two points were not easy to achieve at home.

Lin Zhixia temporarily forgot about the hepatitis B vaccine.

In the kitchen, Lin Zeqiu washed the last bowl and wiped the water droplets in the bowl with a clean towel. He tidied up the cupboards and cupboards and finally had time to finish today's homework.

When passing by Lin Zhixia's room, Lin Zeqiu saw that Lin Zhixia was sitting blankly at the desk, seemingly racking her brains over something important.

He knocked on her door and said, "Lin Zhixia."

Lin Zhixia replied unhappily: "What for?"

Lin Zeqiu walked into his sister's bedroom: "Are you still thinking about the vaccine?"

It would have been better if he didn't mention it. His mention immediately aroused Lin Zhixia's worry.

"I don't care..." Lin Zhixia tried hard to convince herself, "I don't care at all."

Halfway through her speech, she left her desk, found a stuffed penguin, and hugged the penguin tightly in her arms.

She buried her whole face in the penguin's gray fur, which reminded Lin Zeqiu of her mother's words—your sister is only nine years old this year, can't you be a little more accommodating to her

Yes.

Although Lin Zhixia has a good memory, strong comprehension, and high IQ, she is only nine years old after all. She is still afraid of the dark, ghosts, aliens, strangers, and going to the hospital for injections.

Lin Zeqiu sat on a chair and said to her, "Hey, Lin Zhixia."

Lin Zhixia looked up at him: "Do you want to scare me again?"

"What are you doing? You always think so bad of me," Lin Zeqiu said impatiently, "I'm telling you, when you get an injection, don't stare at the needle like a goose. Can you just close your eyes?"

Lin Zeqiu recalled the past: "Two years ago, when you were seven years old, your parents took you to the hospital for an injection, and I was there. The nurse held your hand, and you kept looking at the needle, and you kept crying. Who would stare at the nurse like you did when getting an injection?"

Lin Zhixia felt very aggrieved: "I..."

She couldn't utter a complete sentence.

"Take a deep breath," Lin Zeqiu reminded her, "Before the injection, take a deep breath, close your eyes, and trust the nurse. Is it worth worrying about something that will be over in less than a minute? Don't waste your precious time on such meaningless things."

Lin Zhixia held the two wings of the little penguin doll and said, "Brother."

The elder brother spoke in a gentle tone but with rude words: “If you have something to say, please speak up.”

Lin Zhixia asked him: "Brother, are you comforting me? Thank you, brother! When you are scared, I will also help you. For example... next time you see a bug, I will help you kill it."

Lin Zeqiu neither admitted nor refuted. He stood up and left Lin Zhixia's room.

"You ignored me again." Lin Zhixia accused.

Lin Zeqiu stood at her door and said, "Please, I have to do my homework. I have a math test and an English test tonight. I'm not like you. I can't finish a question in a second. You stay here and don't bother me. Don't bother me."

"I don't want to pay attention to you." Lin Zhixia declared.

"That's great," Lin Zeqiu replied, "I have nothing to say to you."

After saying this, Lin Zeqiu walked back to his own bedroom. He turned on the desk lamp, took out his homework from his schoolbag, and placed it one by one on the table.

The desk lamp was on, casting a light yellow halo, creating a warm mood.

Lin Zeqiu drew aside the curtains, and the night blurred the lights of thousands of houses, and a few lonely stars were vaguely visible in the night sky. He pulled out a chair, sat down casually, picked up a black pen, and concentrated on his math homework.

Today's math homework is a test paper.

Lin Zeqiu spent forty minutes writing the last question, but his thinking suddenly became blocked.

The last question was an additional question with a very flexible type. Lin Zeqiu suspected that this question went beyond the junior high school mathematics syllabus.

He pondered for twenty minutes before remembering that he still had English homework to finish. If he spent too much time on math, he would have to go to bed very late tonight.

But he is the math representative in the class.

Tomorrow morning, the head teacher, who is also their math teacher, will ask the whole class to exchange test papers and grade each other. While correcting the test papers, the head teacher will introduce the solution methods.

It is feasible to give up the additional questions. However, as the math class representative, Lin Zeqiu would lose face.

He sighed softly.

Outside the bedroom door, Lin Zhixia's voice floated: "Brother."

Lin Zeqiu turned around suddenly: "What are you going to do?"

Lin Zhixia ran into his room and said, "Twenty minutes ago, I came out to get some water and saw you in a daze. Twenty minutes later, you're still in a daze... Why? Brother?"

"No reason," Lin Zeqiu covered his test paper, "Stop talking nonsense and take care of yourself."

Lin Zhixia brought a chair and placed it next to his seat. She sat down at the table without hesitation, trying to peek at Lin Zeqiu's math test paper.

Lin Zeqiu was very determined and refused to let go. Lin Zhixia grabbed his fingers and read the questions through their gaps.

She guessed the intention of the questioner without even reading the entire question.

She reminded me seriously, "This problem can be proved by mathematical induction. After all, the difficulty of junior high school mathematics is not high, and induction is enough. You transform this proposition into... For each element in the positive integer set n in the question, there is a corresponding ordered real number array a. When n is less than 2, the condition is obviously established. When n is greater than or equal to 2, the newly added array data c should be..."

Lin Zhixia wrote a concise and easy-to-understand equation.

Lin Zeqiu caught the flash of inspiration in his mind. With the help of his sister, he successfully completed the additional question in four minutes.
