1991 Starting from the core

The Spring Festival does not mean spring, nor does spring mean spring warmth, but compared to the all-day haze a few years ago, it will always make people happy to have a little more sunshine.

Every time I return from annual vacation, the hardest work is always the uncles and aunts in the logistics department. They take vacation last but are the first to receive it. Of course, the security department is also working hard. Even during the Spring Festival, there are people on patrol around the clock.

Su Yuanshan returned to Yuanxin two days early - because Ye Rudai came over.

Ye Rudai still likes the simple and elegant black and white combination. She wears jeans, sneakers, and a white down jacket that is extremely resistant to stains on her upper body.

Well, she always carries sleeves in her pants pocket.

"Last month's national preselection exposed a problem. Our teamwork skills are too poor." Ye Rudai and Su Yuanshan walked side by side to Yuanxin's apartment. They hadn't seen each other for less than a month, and it was another Spring Festival. She has lost some weight, but her eyes are much brighter.

The budget competition she was talking about was naturally the ACM-ICPC, the Asian qualifier of the International College Student Programming Competition sponsored by Yuexin.

As an outstanding contestant from the National Programming Competition for Middle School Students, Ye Rudai was mentored by Xi Xiaoding at Yuanxin. Of course, her team won second place without any danger and qualified for the finals.

The other two teams are from T University and Zhejiang University.

At the end of April, these three teams will go to Philadelphia to compete with more than 100 teams for medals and championships.

"So your teacher Gao lets you go solo?"

"Um?"

"Well, it means you fight alone."

Ye Rudai pursed her lips and sighed faintly: "Of course it's impossible to say it clearly, but he has high hopes. That's why I wanted to come here early and follow Professor Xi to improve further - won't it be too troublesome? "

Su Yuanshan chuckled and said: "How could it be? You will have to enter Yuanxin sooner or later. I won't suffer any disadvantages by training you now."

Ye Rudai smiled and opened her mouth but didn't know how to refute.

Indeed, her plan is to hang out with Xi Xiaoding from now on - she likes the atmosphere of Yuanxin so much. It is just like a university campus, or even better than a campus. Everyone can do what they like quietly.

After sending Ye Rudai's salute back to the dormitory, the two of them headed to the cafeteria.

Since the canteen staff just started cleaning and washing tableware and kitchen utensils yesterday, today's work meal was very simple.

"Hey, Mr. Shan."

Seeing Su Yuanshan enter the door, the canteen manager, who had also arrived early, hurriedly greeted him, rubbing his hands with an embarrassed look on his face: "Today's food is a bit casual, how about I ask someone to make two stir-fries right away?"

Su Yuanshan took a look at the vegetable pots and found that there were really only three big pots, with only one meat and two vegetables, plus a bucket of clear soup that was like pot water.

"Don't bother, it's cold..." Before Su Yuanshan could finish his words, he saw the canteen manager's gaze turned away. He subconsciously looked back and saw Xi Xiaoding and Qu Hui appearing at the door at the same time.

"Senior brother? Sister Qu Hui?" Su Yuanshan turned around, he was a little surprised.

The four people here are not very particular about food, especially Xi Xiaoding and Qu Hui, who are busy, so they just let the canteen cook tomato and egg soup.

As early as this summer, Xi Xiaoding bought a house in the provincial capital and brought his mother over, officially settling in the provincial capital.

Qu Hui himself is from the provincial capital.

During the chat, Su Yuanshan learned that Qu Hui pulled Xi Xiaoding over, not because he thought for a moment that "these two people are actually getting involved", but because there was something wrong with Qu Hui's mechanical CAD.

From the beginning, the earliest source code of Yuanxin EDA was used for mechanical CAD drawing tools, especially vector lines.

In graphic design, drawing a smooth and standard curve is the most basic function. Yuanxin’s initial curve tool used Bezier curves - this was enough when designing integrated circuits, but once it was transferred to CAD and started industrial modeling, Bezier curves could not be used. Continuity required for industrial modeling.

This caused Qu Hui's team to collapse at the time. Later, when Xi Xiaoding returned from the west, he brought back the latest international standard PHIGS (Programmer Hierarchy Interactive Graphics System) for interactive graphics programming interfaces formulated by the International Organization for Standardization. It provides curve standard functions required for industrial modeling.

——Non uniform rational B-spline, referred to as NURBS, the Chinese name is translated as non-uniform rational B-spline.

Now comes the problem - CAD will crash from time to time when using new functions to draw industrial curves.

"Then I'll leave the leaves to you two." Su Yuanshan immediately got dizzy when he heard this.

Qu Hui glanced at Ye Rudai who looked confused and said dissatisfied: "What about you?"

"I'm going to make a Hall device." Su Yuanshan chuckled.

…

As employees return one after another, the science and technology park has also returned to life and bustle.

The third day, Monday.

The first high-level meeting after the Spring Festival was successfully held under the chairmanship of Chen Jing.

Now Su Xinghe has completely separated from the daily affairs of the science and technology park. Even when he appears in the science and technology park, he and his eldest apprentice Qin Weimin discuss supercomputer design plans.

In the conference room, Chen Jing was sitting in the main seat. On the left and right sides were Wang Rui, Wan Yongliang, Liu Hongyan and others from the enterprise side. On the right are Xi Xiaoding, Su Yuanshan, Qin Weimin, Tian Yaoming, and Li Mingliu who finally arrived after the year.

Although Chen Jing was in charge of the overall situation, she was still mainly responsible for the corporate aspect. After making arrangements for this year's corporate goals, she signaled Su Yuanshan to start.

This is also a tacit understanding between several people. Xi Xiaoding is not good at and does not like specific management affairs. Although he has a high position and authority, he prefers to be a mascot. If anyone comes to him with something, he usually leaves it to his graduate students and secretaries to solve it.

"The R\u0026D center has three main tasks this year."

"The first one is the integration of YX architecture and baseband." Su Yuanshan said, looking at Qin Weimin and Tian Yaoming: "Two senior brothers, you have to work hard."

Qin Weimin and Tian Yaoming nodded.

"The second one is the processor team, Senior Brother Gao..." Su Yuanshan looked at Gao Xiaodi who was next to Li Mingliu: "The mask design will be completed before the end of this year."

Gao Xiaodi looked serious and said in a deep voice: "Okay!"

Su Yuanshan nodded and frowned without leaving any trace.

Last year he took Gao Xiao for the first year. This guy still has the ability, but he still lacks a little experience. Letting him lead the CPU group was Su Yuanshan's last resort.

Su Yuanshan has a lot of things going on this year, and it is unlikely that he will focus on the CPU again.

Moreover, Li Mingliu has already said that he will work hard on the second level cache and will not involve it in the architecture this year. And in charge of the CPU team, you still have to be an architect.

At present, the most outstanding architect of Yuanxin is naturally Su Yuanshan, followed by Qin Weimin, and then Gao Xiaodi.

"Third, Senior Brother Li, you can continue to work on your L2 cache, but you have to find a team for me over there."

Li Mingliu leaned forward a little and met Su Yuanshan's eyes: "What team?"

"NAND Flash Memory"

Su Yuanshan paused as he spoke: "You can call it NAND flash memory. You should be involved in related technologies."

As Su Yuanshan finished speaking, the technical people around him looked at him at the same time.

Li Mingliu's eyes flashed: "The one made by Hitachi? Is it a memory that can replace NOR?"

"Yes. Although NOR is fast, it is expensive. NAND can be made very cheap, and the related technology is relatively mature now. The only problem is that the capacity has not been increased yet."

"So I have a little immature suggestion."

Li Mingliu said in a deep voice: "What's your suggestion?"

"Fight NAND and create a new architecture."
