1991 Starting from the core

Su Yuanshan was once responsible for logic design, and he knew that Gao Xiaodi was one of the few "tall men among men" in China.

Engineers who engage in logic design generally have solid mathematical skills. As we all know, people who are good at mathematics are always a little proud.

When the IC design team was first formed to develop decoding chips, most of Su Yuanshan's group also selected people with better mathematical foundations. Thanks to Su Yuanshan personally taking charge and the team leader being Li Mingliu, a top student from T University who refused to accept anyone except Xi and Su, they were able to control the situation. Otherwise, Xiao Shouping and Gao Xiaodi would have to fight each other.

But now, Gao Xiaodi was extremely excited - the arrogance of being a novice instructor for half a year was gone.

Now that Li Mingliu is sent by Su Yuanshan to Shanghai to work on cache, it means that the CPU team here will be directly led by Su Yuanshan - since completing EDA, Su Yuanshan has not personally led the team to do any project again...

Then who else is the actual person in charge of the CPU team here besides Gao Xiaodi?

Su Yuanshan instantly saw through Gao Xiaodi's little thoughts. He chuckled and said, "Senior Brother Gao, you can't lead the X86 team."

Gao Xiao was startled for the first time and immediately became unconvinced: "Why can't you lead me?"

Su Yuanshan appreciated this "why", but he still shook his head: "X86 is a complex instruction set with many addressing methods, which will inevitably lead to a complex structure... and now it is mainly in the architecture and module design stage."

"We will use joint development with Cyrix to advance progress. They have accumulated a lot of experience in the reverse engineering process, so we have to listen to their opinions in the early stage and fully understand the experience they have gained. Then we will choose what we are good at. field."

Gao Xiaodi was startled again.

He is proud, but he is not so arrogant that he thinks he is the best in the world. Although Yuanxin and Xinghai are sisters in name, they are still foreigners on the other side. For cooperative development, if Yuanxin wants to take the initiative, it must send a big boss to lead the team.

And to suppress the Cyrix gang who are already "experienced" on the other side and have even built a CPU, only the big guys can do it.

There are only two such big bosses in Yuanxin.

Xi Xiaoding and Su Yuanshan.

But Gao Xiaodi still wanted to confirm: "You mean you will lead the group yourself?"

Su Yuanshan smiled and nodded: "Well, I will lead the team and be responsible for the MMX instruction set and overall architecture."

Although the core codename is named "Thor", it is actually the P55C core, which is the Pentium MMX core.

Su Yuanshan originally wanted to go directly to what he is best at, which is the Klamath core used in Pentium II, but after careful consideration, he found that it would not be possible to fly with these people, and it would take four or five years to complete it - by then day lilies would be useless. It's cold. So I had to settle for the next best thing and start with MMX first.

As a "commercial spy" who once worked at Intel, Su Yuanshan couldn't copy too obviously. He had to wait until Cyrix's technical files came over and then adjust the architecture based on the level of technology they mastered.

When Gao Xiaodi heard that Su Yuanshan personally led the group, he was completely convinced.

The three chatted for a while, and Su Yuanshan returned to his office.

Before he entered the door, he saw Tian Yaoming walking around in front of his desk.

"Senior Brother Tian, ​​are you looking for Cricket?"

Su Yuanshan opened the door with his shoulder and smiled at Tian Yaoming.

But obviously, Tian Yaoming had no intention of joking with him today. When he saw Su Yuanshan entering, he strode forward to greet him: "I received news that Nokia's GSM mobile terminal is ready for mass production."

Su Yuanshan was startled for a moment, then immediately smiled and said: "What does that matter? The GSM standard we use was originally developed in Europe. It is only normal that they produce mass production machines first. It's okay, you can just do it slowly."

"It's a big deal! Now we are two teams with nearly 300 people! There are also about 100 Silicon Valley elites! There are less than 200 people working on GSM in Nokia." Tian Yaoming stamped his feet anxiously: "The main thing is Whoever produces a mass-produced machine first will be able to participate in the promotion of the GSM standard."

"It's still early. We haven't considered what network to use in China yet, so don't worry." Su Yuanshan chuckled and said, "Senior Brother Tian, ​​you wouldn't just talk to me about this, would you?"

"Hey, you're the boss." Tian Yaoming was exasperated: "Of course that's not what I'm talking about. In fact, the baseband here is almost the same. We only need digital signal processing and two algorithms that have not yet been completed - Mr. Xi is not coming back. Are you ready? Can you ask Mr. Xi to help?"

"No." Su Yuanshan immediately refused.

"..."

Su Yuanshan sighed: "Brother, Brother Xi's algorithm is powerful, but it will take time for him to become familiar with your project. And he is not omnipotent. He cannot solve it as easily as solving equations. Right?"

Tian Yaoming was silent for a few seconds and sighed.

"Furthermore, Senior Brother Xi is currently compiling books and teaching new students. He has always wanted to develop mathematics software. It is always not good to drag him in halfway. If you really only lack algorithms, we can go to mathematics Let’s look for it in the academy.”

"Besides, I'm really not in a hurry about GSM. You guys should work steadily and practice the basic skills well. Our breakthrough period will be in the follow-up with faster and more stable 3G and 4G networks."

Su Yuanshan thought for a while and said: "If you are really anxious to produce results, I have an idea - do you have an engineering prototype?"

Tian Yaoming said: "Over in Silicon Valley, the GSM Standards Committee has set up a base station, so Howard is going to stream a video to test and see if the early efforts have been in vain. But according to Howard and I's estimation, the BUG should appear in the call quality. above."

After saying this, Tian Yaoming sighed again: "I only know that this matter is about to be tapered out - this sentence is true or not."

Su Yuanshan Yile: "Yes, so building a SOC costs money..."

"What's your idea?"

"Well... GSM is a digital signal, so in theory it can transmit text. Since all you have left is the algorithm, don't let everyone fight to the death and change your mind. Go to Brother Jiang upstairs to cooperate. Let's see Can you build a system for GSM that can forward text messages, something like..."

"Holy shit! Got it!"

Tian Yaoming just sat down and immediately jumped up after hearing the text message!

He started by developing Chinese digital pagers, and of course he knew that digital signals could transmit text. And the GSM standard goes beyond that, it can also connect to the Internet...

Tian Yaoming's eyes flashed, he took a few rapid breaths, and then clenched his fists: "Mobile communication terminal equipment is no better than paging. It has the ability to send and receive, and it also has encoding capabilities. We can indeed achieve point-to-point text communication! It's similar to send email!"

"Well, that's right. It's similar to sending emails. Each mobile communication terminal - it will be easier to call it a mobile phone in the future. Each mobile phone has a fixed number, which is equivalent to a mailbox, and the base station is similar to a mail server... There is no one yet Put forward this standard?”

Su Yuanshan looked at Tian Yaoming with a smile.

Tian Yaoming chuckled: "No, Howard stares at ETSI (European Telecommunications Standards Institute) every day and is very sure that there is no such standard."

"Then do it quickly. This should be easy for you. By the way...this text message is called a text message."

"Mobile phone... text message." Tian Yaoming repeated, nodded and said: "It sounds pretty smooth, that's it."

Of course Su Yuanshan's thoughts were smooth... Later generations called him thirty years.
