1991 Starting from the core

Su Yuanshan took Qin Weimin to discuss the microcode all afternoon. He didn't care how much Qin Weimin understood it - according to his understanding of Qin Weimin, if Qin Weimin really didn't understand it, he would definitely ask himself in three days - these three days are Qin Weimin's Rules you set for yourself.

When picking up his bicycle after get off work, Zhu Jianting, who was passing by, saw Su Yuanshan's rare happy face and couldn't help joking: "Are you going to meet that girl with me?"

"What?" Su Yuanshan was stunned for a moment before he remembered what Zhu Jianting was talking about. He laughed, got on the bicycle and pedaled hard: "How can a girl be as caring as CPU?"

"Is it Qin Weimin who has achieved results?" Zhu Jianting was riding a bicycle and walking side by side with Su Yuanshan. He was from Tian Yaoming's group and was currently working on the baseband.

"It's not a result, it's just some progress." Su Yuanshan replied with a smile. He and Qin Weimin had discussed it and the matter would not be made public for the time being to avoid irritating Tian Yaoming.

"..."

The two chatted casually. When passing by Taiping Street, Su Yuanshan raised his head and glanced at the huge signboard of the Computer Training Department. Zhu Jianting stopped the car under the sign and raised his head at him: "Why don't you go up and take a look? There are several young girls learning programming inside, and they are all quite beautiful."

"Senior Brother Zhu, as a grown man, you shouldn't imitate other people's love affairs. I can't tolerate your little girls." Su Yuanshan smiled, pedaled, and quickly merged into the flow of bicycles.

Su Yuanshan knew very well how Zhu Jianting, a man from the electrical science and engineering field, looked at things. He could regard five points as ten points. The so-called beauty could only mean that the facial features were not crooked.

…

Zhu Jianting turned into the alley, locked his bicycle, put his bag on his back and walked to the training department on the second floor.

Thanks to Yuanxin's commuting time, Zhu Jianting was able to catch the first class in the evening, which started at 6:15. During the break, he had a packed lunch, and then went back to the rental house after another class. It was exactly nine o'clock, and he still had time to read a book.

The Oriental Computer Training Department rents a two-unit private house. The owner is Sun Xihui’s cousin, a buddy who dropped out of the Provincial University. He had been selling assembled computers before. This year, he sensed business opportunities from the electronic circuit and programming competition. So I spent all my money to set up such a training department.

There is a large class in the living room, which teaches basic languages ​​such as Basic and basic operations such as typing. Most of the people who come to learn are junior high school students, and occasionally high school students. There is a small class in the master bedroom. To be precise, it is a professional class specially designed for this competition. All classes are taught in C/C++.

Zhu Jianting entered another office that had been converted into a bedroom, greeted his boss first, and then opened the door to the small class room.

A girl who was combing her hair in a ponytail in front of the computer immediately raised her head and looked towards the door. She was wearing a long black skirt, a white short-sleeved shirt, and a ponytail. She was clean and fresh, and her facial features were delicate and attractive, especially her eyebrows. Her eyebrows seemed to have been specially trimmed, with a moderate density and greenness, and her eyes were large and energetic.

When she saw Zhu Jianting, the girl unconsciously clenched the cap of her pen.

Zhu Jianting smiled slightly: "Xiao Dai, come out."

The girl immediately pulled up the stool and strode to the door. Zhu Jianting closed the door smoothly, glanced at the hall again, pulled out the floppy disk, and said in a low voice: "Is this your entry for the competition?"

The girl pursed her lips and nodded, looking at Zhu Jianting expectantly.

Zhu Jianting smiled: "I didn't modify it for you."

The girl was startled and frowned slightly, but she soon recovered from her disappointment and whispered softly: "Thank you, Teacher Zhu."

"But I pointed out the location of the bug to you, and you can fix it yourself - by the way, don't thank me, it was a help from a great programmer."

"ah?"

Zhu Jianting opened the door and blinked: "You can find out by opening the source code yourself."

…

When the girl returned to the machine, she suddenly became a little nervous when she thought about what Teacher Zhu said about Daniel's help, but she immediately laughed silently. Daniel helps, does he have to burn incense to read the source code?

Insert the floppy disk, open C++, load the project, and the girl starts checking the code line by line. When I checked the middle position, I saw several lines of comments that were obviously not my own.

/*Hello, the cause of the BUG is the pointer in line 279 of the code. The pointer there will cause a logical error, making the memory redundant, and thus reporting an error.

Your code is very readable and has a certain logic, but it lacks standardization in variable settings, and the code can also be streamlined. Since this may be your entry, it is just a reminder. Don’t forget to delete this comment, above. */

The girl bit her lip, her eyes flickered, and she suddenly laughed.

A girl next to her turned her head curiously: "Diel, what's wrong with you?"

"Looking at Daniel's comments."

"Wow? Let's take a look!" The girl left her seat, lay on the girl's shoulder, and praised after reading the annotation: "It's really the tone of a great guy - but is what he said useful?"

"I don't know, let me check."

The girl named Daier started checking along the prompts. Five minutes later, she found the error and made corrections. Then she debugged and the bug disappeared.

"Yes!" The girl clenched her hands into fists, her face flushed.

"Done?" Zhu Jianting looked at her with a smile from behind.

"It's done! Thank you, Teacher Zhu, thank you...that Mr. Daniel! Is he your instructor?"

"Haha!" Zhu Jianting laughed, shook his head and said: "He is about the same age as you, but he is a real genius in programming."

"Huh?" The poor girl was a little dumbfounded.

Zhu Jianting smiled: "Stop, delete the comment, you are very likely to win the prize."

The girl came back to her senses, nodded, read the note one last time, and then pressed the delete key.

Seeing Zhu Jianting walking away, the girl took a few deep breaths, thought about it, took out her notebook, and wrote a short thank you letter.

When writing the signature, she hesitated for a moment and decided to write down her pseudonym - Dai Peiye.

Although I completed the whole process independently, I didn’t ask for help until the end when I really couldn’t figure out the bug. But this is an entry after all, and it would be meaningless if she encountered some malicious people who reported her for spending money to attend training classes and find teachers. So she used a pseudonym at her father's suggestion when she signed up for the training class.

It is now approaching the end of August, and she will soon leave the provincial capital and return to Penang to continue her sophomore year of high school.

I hope I can win an award. The girl thought to herself, tore off the pages of the notebook, and folded them briefly, but unknowingly, they folded into a small boat.

After returning home, Su Yuanshan couldn't wait to tell his father the news that Qin Weimin had developed an obstacle patent. Su Xinghe was very happy after hearing this, and quickly called Qin Weimin and left a message, asking him to keep working hard.

During the meal, the father and son inevitably chatted about their respective progress. The microcontroller team led by Su Xinghe benefited from the fact that the architecture was finalized by Qin Weimin, so the progress was pushed forward very quickly, and it has now entered the stage of microcode debugging. According to this efficiency, it is estimated that the microcontroller will be able to tape out pictures in less than two or three months.

During this period, Su Xinghe laughed and talked about Qin Weimin's bet with him, but was blocked by Su Yuanshan. Both the master and the apprentice were engaged in chips, and the master led a group of professors and graduate students, and No. 34 people worked together to tackle the problem. On the apprentice's side, there are about twenty graduate students and undergraduates... who are still working on a CPU architecture that is more difficult than a microcontroller. It would be really shameful for this master to lose.

Su Xinghe knocked on his son, and then sighed: "But after the microcontroller comes out, it must be accompanied by an application program. Several of our professors discussed it. If the tape-out is successful, an urgently needed application must be developed. . And the supporting teaching materials are also a problem - the teaching materials for microcontrollers are not as good as EDA. There are too many knowledge points involved, and it is a bit troublesome to compile."

"Dad, I don't know if you have heard this sentence. First-rate companies make standards, second-rate companies make brands, third-rate companies make products - we are at the forefront, and setting standards is our goal. For example, let all relevant Professional college students all use the microcontrollers you developed and the textbooks you compiled. This is because you have set the standard. So don’t find it troublesome."

Su Xinghe nodded. He agreed with his son's point of view: "Yes, now all the standards for computers, communications, and the Internet are set by foreigners, and we must cooperate with them. In the long run, our innovation ability will disappear."

"So let's work hard and innovate." Su Yuanshan picked up a chopstick and chewed the vegetable.

"I see you're working hard to prepare for the new semester." - The mother who was standing by as if listening to a book from heaven finally seized the opportunity and stared at Su Yuanshan.

"ah?"

"Ah, what, you don't want to ask for leave, do you? Lao Su, are you sure your son can really win the special prize? Aren't you afraid that others will report that you are using public money for personal gain?" Zhang Xiuyun put down his chopsticks and glared at her husband and son.

Su Xinghe was startled for a moment - even though the whistle-blowing trend has passed, who can guarantee that no one will be jealous? But he immediately smiled proudly.

"Whoever is his son knows that Xiaoshan's programming is strong. Let alone his peers, if I have one-tenth of his ability, I will lose!"

Su Yuanshan coughed and remembered the code he saw at noon today.
