1991 Starting from the core

Watching Bresman leave with a smile, Su Yuanshan suddenly stopped smiling and asked softly: "Why do you think he asked me that last question?"

Xi Xiaoding's eyes flashed, and then he smiled arrogantly: "Even if they set up an EDA development alliance, as long as we don't go astray, they can't catch up with us. Their advantage is that they can integrate with advanced production lines, but this It’s just a service advantage, not a technology development advantage.”

Su Yuanshan nodded. He knew that Xi Xiaoding had one more thing he didn't say, and that was the algorithm. The algorithm of Yuanxin EDA comes from the early patents of Su Yuanshan and the self-owned patents added by Xi Xiaoding later. During the development, the two of them continued to expand the patents. It would be fine if peers don’t decompile, but if they decompile and want to imitate others, as long as they encounter the algorithm, it will be a bit unlucky...

As an industry software, Yuanxin EDA's legal statement of course prohibits decompilation - of course you can't catch someone doing it secretly. As long as the source code is not disclosed or copied for personal use, most people will turn a blind eye.

The problem is that the core reason why Yuanxin is convenient, fast and intelligent is based on the algorithms of Su Yuanshan and Xi Xiaoding - once peers decompile and understand the algorithm, it will inevitably interfere with peers' development of similar algorithms. Unless you are determined to bypass patents and copycat.

But that's easier said than done? Su Yuanshan, who knew the various operations of building patent barriers in later generations, spent a lot of money to ask Yang Yiwen to find an agent to supplement and expand their patents when Yuanxin was still poor. This was not for the sake of copycats.

At this time, three white guys came behind and sat down. Su Yuanshan looked back and said softly: "Having said that, we still have to pay attention. Currently, the only ones with technical strength among the peers are Synopsys, Cadence and Mentor. It doesn’t matter if other small companies collapse. We must pay attention to the changes in these three companies, especially mergers.”

Xi Xiaoding nodded. He knew that EDA was the core and foundation of Yuanxin. It was so important that the branches here only had sales and debugging rights - Xi Xiaoding himself did not dare to carry out subsequent development here.

Now that the coffee was bought, everyone sat and chatted casually about where the house would be rented, and gave Su Yuanshan suggestions on what to buy to take back home - Su Yuanshan had to bring a large bag of gifts back home.

The three boys next door took out their change from their pockets and gathered together to let one of them buy coffee, while the remaining two chatted quietly with newspapers. Su Yuanshan was closest to them, so he could hear the two of them complaining that they would go hungry if they didn't find a job.

Not long after, the guy who bought the coffee came back and started excitedly chatting about technical issues with his two companions. It could be seen that his two partners were very perfunctory, their eyes constantly wandering over the recruitment advertisements in the newspapers.

"Hey! Buddy! Don't be like this, you two, we will solve the baseband problem soon!" The guy buying coffee was a little annoyed: "Isn't it just that MOTO is blind?"

The companion was helpless: "Howard, we have no living expenses."

Su Yuanshan turned his head and saw that the man named Howard was probably in his early twenties, with fluffy curly hair that was a bit greasy. He was wearing a long-sleeved autumn coat and a short-sleeved T-shirt.

"I agree with the statement that MOTO is blind." Su Yuanshan said in fluent English. He looked at the guy buying coffee with a smile: "What did you just say about wearing a gay belt?"

"Yes, we have a very cool idea! It can bring..." Howard immediately became excited when he saw someone chatting with him, but immediately realized something was wrong. He shook his head and smiled: "You don't seem to be a rich man, so you won't say anything. ”

Pfft...Su Yuanshan coughed: "If I heard you right just now, MOTO should have rejected your request for sponsorship, so you said MOTO is blind. But you didn't even ask me and you thought I was not a rich person, then you What does this mean to me?"

Howard smiled and scratched his head: "I'm afraid you don't understand. We have developed a very cool short-distance full-duplex radio communication protocol."

Su Yuanshan raised his eyebrows, and a flash of surprise flashed in his eyes.

A short-distance full-duplex wireless communication station. To put it bluntly, this thing is similar to a walkie-talkie or a walkie-talkie - but these two are half-duplex. They can only have a sentence-by-sentence conversation, and after speaking, they will shout OVER. Full duplex is the phone mode, which can send and receive data at the same time.

Put it this way, this thing can be understood as a dysfunctional big brother in a sense. It is no wonder that MOTO ignores them.

But Su Yuanshan knows that this thing is not useless, but has great uses! He was even leading a certain group of Tian Yaoming's team responsible for communication protocols to this direction intentionally or unintentionally.

Connect it to local calls, and it will be the famous advertisement "Hey, Xiaoli" - a cordless phone.

"Say, continue." Su Yuanshan motioned to Howard to continue.

"Forget it, you haven't realized what changes it can bring after hearing this, so there's no need to tell you." Howard shrugged and showed his hands to Su Yuanshan: "Although we have reached a consensus on MOTO's blindness. , which makes me appreciate you very much.”

The people behind Su Yuanshan were extremely happy, but after laughing, Xi Xiaoding and Chen Haoming started to think about it. As for Su Yuanshan, he smiled slightly and said slowly while Howard turned around: "Connected to the local telephone system, this wireless full-duplex radio can turn the local telephone communication terminal into a short-distance mobile terminal."

"Oh! F**K!" Howard turned around and stared at Su Yuanshan like a ghost, showing an exaggerated expression: "You...can you understand?"

"You can probably understand, how many protocol layers do you have? Is it five layers?"

Howard's eyes flickered, and finally he gritted his teeth and nodded: "Damn it! Are you a little bad guy from Xia Guozhong University of Science and Technology?"

Xi Xiaoding moved his eyebrows and finally smiled.

Su Yuanshan coughed twice: "Then if I guess correctly, to realize your idea, the baseband should require two ICs, one digital-analog hybrid circuit, and one main IC to complete the signal source, channel encoding, modulation, and encryption. At the same time, a radio frequency IC is needed to complete frequency modulation and demodulation. Do you have the design capabilities for these chips?"

"We... have completed the coding of the baseband and will be able to complete the design of other chips soon." Howard's eyes were frightened. He did not expect that Su Yuanshan could even report what chips he needed: "You... don't tell me that you also Doing this.”

Su Yuanshan smiled and shook his head.

Howard breathed a sigh of relief. At this time, his companion had already turned over the pages of the newspaper, looking at a piece of news about yesterday's exhibition, and looked up suddenly when he saw a picture.

"Howard..." The companion touched Howard gently.

"Damn it, don't interrupt." Howard ignored his companion and stared at Su Yuanshan with stern eyes: "Man, since you understand and have guessed the future of this technology. Now it depends on whether you are rich and whether you are related to Su Yuanshan. MOTO is just as blind."

Su Yuanshan coughed.

He remembered that the first cordless phone was made by Siemens - did this guy sell himself to Siemens out of desperation?
