After returning home with his father, Su Yuanshan accompanied his mother to watch the TV series "The Legend of Yiwei High Roller", and was inevitably muttered by his mother in the middle, and he was not liberated until his father took a bath.

Standing under the faucet of the water tank, Su Yuanshan's mind was full of chips.

The structure of the BB machine is not complicated, the signal is received through the RF antenna, and then transmitted to the decoding chip after filtering, and then transmitted to the register and finally to the output unit, such as the screen and speaker. The decoding chip is not complicated, just a highly customized CMOS chip. But now Su Yuanshan wants to set a Chinese character coding standard, which is a bit troublesome.

At this stage, the paging station is basically controlled by Motorola and Pioneer, and it uses a cassette microcomputer for encoding. It stands to reason that as long as you build a single-chip microcomputer - but it is obviously unrealistic to expect Lao Su to build a single-chip microcomputer in one or two months.

Since this is the first battle for Yuanxin to go out of the industry, it must have all independent intellectual property rights, otherwise what is the obligation?

"It seems that we have to find a time to go to the paging station to take a look at the scene, so that the blind man and the blind horse will get into trouble. ”

After taking a bath, Su Yuanshan returned to the living room to say hello to his parents and was about to enter the study, but was stopped by his mother Zhang Xiuyun.

"Xiaoshan, I just heard your dad say that the competition has been officially announced. How are you preparing to run to your dad's company every day?

"Huh?" Su Yuanshan glanced at his father, only to see that his father also looked helpless.

He had no choice but to smile and say, "It's okay, I'll just write a little software when the time comes." ”

Zhang Xiuyun was immediately unhappy when she saw his attitude: "What kind of attitude do you have! Ask your father to give you a semester off, just let you treat it casually?"

"Uh...... Mother. Su Yuanshan couldn't cry or laugh: "Then I'll take it seriously." ”

Zhang Xiuyun snorted and said: "You must be energetic, don't think that if you know a little bit about computers, your ass will be in the sky." This time your opponent is all the middle school students in the country, including technical secondary schools and vocational high schools!"

Su Yuanshan looked at his father in surprise, he knew that the game would definitely pass, so he didn't pay attention at all. I didn't expect secondary school students to come and intervene.

My father was a little helpless, and said with a smile: "The Ministry of Education and the superior mechanical and electrical department of our school feel that since it is the first time to do it, it must be done in a good way, and if it is limited to junior and senior high schools, there may not be many things on the table, so all secondary and full-time high-tech schools are added." ”

Su Yuanshan couldn't cry or laugh: "Isn't this cheating, how can high school students compare with secondary school students? ”

His mother continued to glance at him: "What do you think? ”

I won't say what the technical secondary school will be like in the future generations. But before the mid-90s, almost all of the students who could be admitted to the technical secondary school were excellent students - especially those top students from poor families in rural areas.

Now the state has pulled out this group of people, which is equivalent to the ratio of amateur players to professional athletes.

"No way, after all, it's the first time. However, the plan of the electrical department has not changed, and the secondary school students who can get the special prize from the whole country must not be ordinary people. ”

Then Su Xinghe briefly introduced the rules of the "First National Electronic Circuit and Programming Competition for Middle School Students".

The first session has both the inside and the face, and there can be no mistakes. Therefore, the method of national solicitation and two rounds of selection is adopted. The contestants of the final grand prize and the first prize call the department for their final statement, similar to the defense, to prevent gunmen and cheating.

An electronic circuit, a program design, these two special prizes will be directly qualified for admission to the electrical department, the first prize will be exempted from the examination or the extra points for the examination of the electrical department according to the situation, and the second and third prizes will only be awarded certificates.

The deadline for submission of works is September 1, subject to the postmark. The judging period is from September to November, and the final award ceremony is December 1.

"Anyway, you have to take it seriously!" Zhang Xiuyun once again sounded the alarm to Su Yuanshan.

"I know, I'm going to take it 100 percent! I'm going to type the code!"

Su Yuanshan glanced back at his helpless father, and returned to the study with a smile.

Opening the EDA that had been compiled yesterday, Su Yuanshan created a new project, and then set the specifications and described the circuit.

Su Yuanshan "retreated" at home for two days.

......

Su Yuanshan had lunch before riding his bicycle to Jiangdu Building. When he arrived at the company, the grouping had been completed, and the brothers who had joined the MCU team had also moved out of the company and returned to the laboratory of the electrical department.

Originally, this kind of land division of the younger brother would generally be debated for a long time, let alone an hour, even if it was a day, it might not be able to be done. However, there is no such thing as Yuanxin, because a team leader is the BOSS, and a team leader is the director with the highest education and the strongest ability......

The remaining Tian Yaoming, who is still studying for a doctorate, is no longer dissatisfied with him. But after learning that Su Yuanshan would "learn" from him, Tian Yaoming felt with his usual acumen that his group was the most important.

Tian Yaoming was the second batch to come to Yuanxin for "support". As Qin Weimin said, the people who were sent over to help were indeed proud disciples valued by their respective mentors, and they also came with the purpose of rubbing a car.

Who makes Yuanxin EDA so awesome?

However, after several professors in the electrical department who are engaged in integrated circuits, especially single-chip microcomputers, jointly set up a single-chip microcomputer research group, Tian Yaoming felt that he seemed to be unable to come out for a while.

"Senior Brother Tian is early. Su Yuanshan greeted Tian Yaoming as soon as he entered the door.

"Hill early. Tian Yaoming sat in a separate office, in a very happy mood - much cooler than at the workstation.

"Xiaoshan, how do we carry out our work?" Tian Yaoming straightened up, he knew that the guy in front of him, who had only turned seventeen, was a real demon, and he might be able to pull out anything in his mind and shock himself.

"Hmm...... We're mainly engaged in pagers. Senior brother should have studied it, right?"

Tian Yaoming nodded, calm and conceited: "I have studied it in the master's degree, which is quite simple." ”

Su Yuanshan smiled, and his fingertips popped up the rhythm on the floppy disk: "Okay, now our team is a total of 8 people, I am solely responsible for the design of the encoding and decoding chips, and I will give the pin definitions, specifications and functions of these two chips to the senior brother, and the senior brother will let them add them to the EDA component library by themselves." ”

"Well, okay!" Tian Yaoming replied casually, but he was immediately stunned, he frowned, blinked again, and finally stunned for three seconds before his eyes came out, and he stood up with a bang, pointed at Su Yuanshan and shouted: "Fuck! You said that you only took two days to design the encoding and decoding chips?"

"Be quiet!"

Su Yuanshan saw that there was no task assigned in the workstation area, and several senior brothers who were chatting turned around together, and were taken aback: "I just defined the pins, and I haven't written a single instruction yet." ”

Tian Yaoming wiped a cold sweat - he was really scared just now, he designed two special chips from scratch in two days, is this a person? I'm afraid it's not the devil.

"Then you mean we don't care about you?Design PCB directly?" Tian Yaoming looked at Su Yuanshan suspiciously, he knew that Su Yuanshan's programming was very strong, and he didn't know how the integrated circuit was—but no matter what the level was, was this what he should play as a high school student?

"Yes, to be precise, it is necessary to design a pager, but also to design a coding card based on the coding chip that can be compatible with the current paging station transmitter, which needs to be inspected and verified by the paging station on the spot. Senior brother can find a relationship, right?"

Tian Yaoming thought for a while: "No problem, our professional and the post and telecommunications bureau are the counterpart units, and you can find acquaintances by looking around." ”

"So, I went to the workstation to get chips, and the floppy disk had the specifications of the two chips written on it. ”

——This is also one of the innovative features of Yuanxin EDA, which allows any component to be customized into the component library at any time according to the description.

"Good...... Wait, what about the main control IC? And what about the LCD panel IC? Chinese display to change the driver IC. ”

Su Yuanshan stopped, he scratched his head, and he really forgot about these two things. After thinking about it, he asked, "Do you want to post two cow?"

Tian Yaoming couldn't cry or laugh: "You have done all the decoding chips, can you use cow to talk about these two?"

In the low-end circuit board, you can often see a black round chip the size of a fingernail, in fact, it is just a type of packaging that buries components and integrated circuits first and then drops a piece of glue, called bonding, which is cheap, but it is troublesome to repair and replace, and it cannot stand up. Because the shape is too much like a lump of cow poop, it is customary to call it cow.

"Okay then...... You sort out the requirements first, and then come back and tell me. ”

Walking into the office where the workstation is located, Su Yuanshan inserted a floppy disk and imported chip design engineering.

He was right, there was indeed not a single directive written.

Because only the instructions were not written.
