Chapter 92: Starting with MMX

Feedback from Silicon Valley Xinghai came quickly.

As Su Yuanshan judged, after Carly and Xi Xiaoding came into contact with Cyrix, Klaus, one of the founders, was in a hurry. Although the CX486DLC series of low-end CPUs that have just been launched can allow Intel's 386 users to upgrade in situ and enjoy the speed of 486, the foundation is still based on the 386 magic change, and there is no floating-point operation. It can only be done by plugging in an external 80387DX floating-point computing chip, so even if it is cheap, the market prospects are still unknown, and at least it has not received a large number of orders from the local market - don't forget that there is a copycat big brother AMD standing in the way.

Historically, Cyrix really managed to break into the low-end market and become known until 95 years later, when 6X86 and MII were born. When it became famous, Cyrix did not hesitate to sell it to National Semiconductor.

So when Carly tentatively proposed a takeover, Klaus didn't explicitly object to it, he was just surprised, because it defied common sense - there must be a demon when things go wrong, and this sentence is standard everywhere. So Klaus said he and his team needed to think about it.

As the acquisition plan has been advanced, Yang Yiwen, who originally planned to stay in China for a month, had to end her vacation early and return to Xinghai to preside over legal and patent transfer affairs. At the same time, the investment department in charge of Qin Si will also be independent and become an independent subsidiary of Offshore Xinghai, and its main business in the future will be angel investment and patent management.

And there is another reason for going independent, that is, Chen Haoming has graduated with a doctorate and is about to officially join Xinghai and become Xi Xiaoding's successor - for ordinary office romances, Yuanxin's rules are very relaxed, as long as it is not a subordinate or subordinate in the same department. As for the executives, the organizational structure is separated.

After all, Yuanxin is a high-tech enterprise, and it can't be as nervous as a business-oriented enterprise.

......

Seeing off Tang Wenjie and Yang Yiwen, Su Yuanshan went to the construction site again when he returned, and found that he was worthy of the construction supervisor sent by the Ni Guoren, who had been engaged in it for a month, and the dust-free workshop was still laying the foundation. But Su Yuanshan is not in a hurry, Chen Jing has just purchased a batch of motors through Meijie on the island, and is preparing to enter the customs on the Xiangjiang River - Chen Jing told Su Yuanshan that if he can't get out of the island under normal circumstances, then it is estimated that he can only take the waterway.

In his previous life, Su Yuanshan had never played this kind of sassy operation? He could only say, I don't worry about you doing things......

However, Su Yuanshan knows a lot about similar operations, for example, the tile girl who is now lying on the Black Sea and slowly rusting will come to China all the way across Haiti in a few years - everyone thought that she would become the casino licensing lady on Ao Island, but she didn't expect that in the end she would become the first big man in the navy, Sister Liao.

......

Back in the office, Su Yuanshan opened the document and began to recall the MMX instruction set.

The instruction set is not mysterious, and can even be simply understood as a collection of program-specific instruction optimizations. For example, the MMX instruction set is the support for multimedia video - before the MMX instruction set, it required a lot of calculations to play the video, but with the instruction set, the execution efficiency can be greatly improved.

As a former Intel engineer, Su Yuanshan was first exposed to the MMX instruction set, so he knew that this thing was actually the product of compromise. In order to take care of Win95, which has been released for a year, the MMX instruction set adopts a compatible mode and can be executed without any changes made by the operating system.

As a result, not only is it bloated, but it only supports 2D video, with little to no improvement over 3D.

So much so that when AMD launched 3DNow!, Intel hurriedly launched SSE, and then with the continuous improvement of SSE and the continuous enhancement of CPU performance, there was no more MMX to do.

But in this day and age, it's an out-and-out killer. You know, it was only proposed in '96.

Su Yuanshan frowned, staring at the monitor and constantly turning the pen.

Since there was no design engineering for the Pentium processor, he could not simulate and design, so he could only write down the instruction format and some functions of the instruction set from memory, and when the time came to take over Cyirx, he would not hesitate to redesign the core architecture and add MMX.

In fact, now Su Yuanshan can design the new core in advance, but now he is the only one who is good at the X86 architecture, even if he is from the future, he has been a top business spy in Intel for three years, and it is a fool's dream to want to do the core architecture alone.

After thinking about it, Su Yuanshan grabbed the phone and dialed the number of Lin Yonggu's office.

The phone was connected, and after greetings, Su Yuanshan asked, "Mr. Lin, how is the progress over there?"

On the phone, Lin Yonggu's voice couldn't hear the emotion: "It's okay, it's been steadily advancing." ”

"Well, that's a success. Su Yuanshan paused as he said and said with a smile: "Hehe, that ...... Mr. Lin, when will my people come back?"

When Lin Yonggu heard Su Yuanshan ask the question, he was stunned for a moment, and immediately became anxious: "They can't leave now, it's a critical period!"

"......" Su Yuanshan was amused when he heard it: "I didn't say that I wanted it immediately, after all, we are deep partners, even if we want them to come back, we have to greet you a long time in advance, right." ”

Lin Yonggu breathed a sigh of relief and said with a smile: "I thought that the government over there put pressure on them to come back." ”

Of course, he could guess that Su Yuanshan must have sent a group of people over to learn some experience, and it was impossible to take the initiative to recall him, unless he was under some pressure.

In all fairness, at first, UMC was a little contemptuous of the people who came from Yuanxin, but as the run-in period passed and the project continued to advance, UMC found that the people sent by Yuanxin were really not rookies. It's really capable—at least people are smart.

Therefore, the task of the dozen people in the group of Yuanxin is becoming more and more important, and they are now fully integrated into the team, and if they really want to leave, the project will have to be stopped immediately.

"Hehe, the YX chip that my dad showed on the island last time was the one I told you before, and the architecture is purely our own property. I said last time, if you need it, we can give it to you. Su Yuanshan pondered his sentence and said softly: "I know, you also want to take the X86 car." But now Intel is only starting a lawsuit against AMD and Cyrix - can your CPU bypass the 338 patent?"

Lin Yonggu was silent, and after half a sound, he smiled bitterly: "No, no one can get around." ”

"If you can withstand the lawsuit, can you withstand it? If you can withstand it, you can consider laying out the mainland market. If you can't stand it......" Su Yuanshan said and paused: "Actually, I personally recommend that you choose to embrace the YX architecture. ”

Lin Yonggu was silent again and smiled: "This side will be able to simulate soon, as an architect, you have to design a CPU to be willing." ”

Su Yuanshan sighed lightly and said softly: "I can understand, then I wish you good luck - it means that it won't be long before Senior Brother and they can come back, right?"

"Yes, up to three months. ”

"Okay. ”

Hanging up the phone, Su Yuanshan let out a long breath.

In three months, Huajing's side has just been put into production, and its own side has almost sorted out the structure.
