Liang Yuan sat on the sofa and lowered his head without saying a word. After thinking for a long time, he had no idea. However, he could not ask for help in throwing coins in such a thing. After patting his forehead, Liang Yuan decided to put this matter aside for the time being.

"Old Su, I have to think about this and let me first talk about what happened to the new processor? I remember that the next generation of processors were developed on the x86 architecture." Liang Yuan asked curiously.

"The new model of processors is continued to be developed on the x86 architecture, but we now have the opportunity to get a brand new processor." Su Liangyu said with a smile.

Liang Yuan became very interested when he heard that there was a ready-made processor.

"Xiaoyuan should know about Wang An computer, right?" Su Liangyu asked.

Liang Yuan nodded and said, "It is famous and well-known. More than a year ago, I was received by the leaders of the Party and the country. It is an iconic figure of Chinese Americans."

In the history of the entire computer industry, no Chinese can match Wang An’s historical status in the computer industry.

From the 1970s to the mid-1980s, the logarithmic computers, small commercial computers, word processors and other office automation equipment produced by Wang'an Computer Company were the first to propose concepts and invented by Wang'an Computer Company. Wang'an Computer Laboratory once played a leading and pioneering role in the computer field in the United States.

Bill Gates once said that if Wang An Computer Company could complete the second strategic turning point, there would be no Microsoft in the world today, and Bill Gates would not become a hero in the personal computer era.

"I might become a mathematician or a lawyer somewhere," Gates said.

The first turning point in the development of the computer industry was to transform from a military-specific mainframe to a small and medium-sized machine suitable for commercial applications, and entered the fields of word processing, office automation, etc. The second turning point in the development was the rise of personal PCs. Wang An seized the first opportunity, and Bill Gates seized the second opportunity.

"But Wang'an Computer is not having a good time now. In 1986, Wang'an handed over the company to his eldest son Wang Lie, but lost $425 million that year. At present, the stock price of Wang'an Computer Company is still declining. The losses are still continuing." Su Liangyu shook his head with some regret.

"The chip I'm talking about is from Wang'an's R&D department, Wang'an Computer Laboratory."

Later generations have been interpreted by major business schools around the world countless times, from strategy, technology, founder personality, external relationships, etc. All major business schools have admitted that Wang An handing over the company to his son Wang Lie is one of the root causes of the company's accelerated failure.

"My university alumnus Fang Xingdong joined Wang'an's computer work in the 1970s and has been responsible for the research and development of medium-sized commercial computers. After the rise of personal computers in the late 1970s, Lao Fang once suggested that the company follow up, but at that time, Wang An believed that competing with ibm was large, and medium-sized computers were the company's future, and the personal computer market would not have much capacity."

"Although the company did not provide support, Lao Fang used his spare time to tinker with a very simple processor, due to his limited personal energy. When designing, he referred to the mos6502 processor used by Apple computers, and chose a streamlined instruction set (risc) processor architecture."

"Lao Fang worked on it for more than two years before he finished the processor. As a result, the sales of the personal computer market exploded. Due to the situation, Wang An decided to launch the personal computer business. In order to save the development time of new products, Lao Fang recommended the newly designed processor to the company. After testing, Wang An found that the chip had excellent performance and decided to buy the authorization of the processor from Lao Fang."

"Because Wang'an's computers have always been incompatible with ibm's software, Wang'an's personal computer business has not improved much. Due to the company's poor performance, the R&D department has had a big conflict. After Wang Lie took over the company, he believed that the root cause of the company's losses was that the R&D department could not produce good products. It has nothing to do with incompatible ibm software. Lao Fang's views have always been in serious conflict with Wang Lie. In April, he had a big fight with Wang Lie, and finally chose to resign in anger."

Su Liangyu briefly introduced the source of this processor. He continued: "A few days ago, after I received the news that my old classmate had left, I mailed samples of the leafless electric fan and air purifier of the Science and Technology Park to Lao Fang. Then he invited him to work in China. Thanks to your troubles in the United States, Lao Fang is very optimistic about these two products. At the beginning of the month, he returned to China to visit the Science and Technology Park and thought our place was pretty good."

"Oh, Lao Su, why didn't you sign it directly? It's rare to meet a scientist who can like us, the country buns." Liang Yuan said with a smile.

"The problem is that Lao Fang is different from me. He firmly believes that the Risc architecture is the future development direction of the processor. If Lao Fang is invited to work, although there is a ready-made processor available, the subsequent R&D direction of the Science and Technology Park will have to be changed. We do not have the strength to double layout on the x86 architecture and the Risc architecture."

Liang Yuan grinned after hearing Su Liangyu's words. It seemed that every time he went abroad to be lazy, he would encounter more difficult problems when he came back. Not to mention Liang Yuan, Intel, which is almost the same in the world in the future, is only the only one in the x86 architecture. On this planet, developing processors with two architectures at the same time is tantamount to seeking death.

Su Liangyu's R&D direction is mainly focused on the x86 architecture direction. The 6xx series processors created by the Science and Technology Park can be said to be a replica of Intel 80 series processors, and are in a very unfavorable position in patents. Su Liangyu is speeding up to develop the next-generation processors, which is also to avoid certain Intel's patents.

"Old Su, what do you think of these two structures?" Liang Yuan decided to kick the ball over first.

"Xiaoyuan, if I say that these two architectures should have their own strengths, no one overwhelms the problem of each other. The Risc architecture processor has certain advantages in terms of power consumption and operation speed, but the X86 architecture is stronger than the Risc architecture in terms of development difficulty and development tools." Su Liangyu gave a vague answer.

"Old Su, you just came back and threw two big problems at me. It's really inhumane." Liang Yuan said with a bitter face and lamenting.

"If Xiaoyuan feels embarrassed, just draw lots." Su Liangyu said with a smile.

Liang Yuan was relieved when he heard that Su Liangyu was still thinking about joking. Su Liangyu's attitude showed that he was not rejected by Risc architecture. After all, Su Liangyu was the core of the chip laboratory. If he chose the research direction for the transformation of Risc architecture, it means that most of Su Liangyu's previous work was in vain. Liang Yuan had to consider Su Liangyu's emotions.

"Old Su. Show me the information about the new processor." Liang Yuan decided to use his poor computer knowledge to compare the information to see if he could find more familiar words. The more familiar words he found, the greater the potential of this processor.

To test whether a technology is excellent and has a future for development. There is no better way than time.

Su Liangyu opened the drawer of the desk. He took out a medium-thick kraft paper bag from it and handed it to Liang Yuan.

Liang Yuan untied the lanyard from the paper bag and pulled out the documents.

After turning on the cover, Liang Yuan was stunned in the first line of English on the document.

advancedriscmachine. Advanced streamlined instruction set machine, what is this? Looking at the three bright capital letters, Liang Yuan's heart was jumping violently, and he quickly looked at it in ten lines.

The processor developed by Fang Xingdong is slightly different from the well-known arm in later generations. Apart from a lot of professional terms such as addressing space, addressing range, temporary register, counter that Liang Yuan cannot understand, Liang Yuan noticed that this processor uses a 16-bit data bus, which means that this is a 16-bit processor. It looks much more advanced on paper than the 6x series octave processor currently produced in the Science and Technology Park, and is the same level as the new processor under development by Su Liangyu.

In Liang Yuan's impression, Arm, which was established a few years later, officially launched the processor should be a 32-bit microprocessor.

After reading the information, Liang Yuan had a rough understanding of this processor. This processor, named C2 by Fang Xingdong, is very simple. According to the description on the information, only 20,000 transistors are needed to make the processor work.

There is no micro program that is common in the x86 architecture that breaks down a series of complex instructions into relatively simple instructions, and does not include any cache. Compared with the 70,000 to 80,000 transistors integrated into the x86 architecture processor, the extremely streamlined C2 only requires very little power to maintain the processor's normal operation.

Due to the very small number of integrated transistors, the c2 processor has low cost and low power consumption characteristics, and uses a streamlined instruction set in processor control. It enables c2 to have extremely high program execution efficiency under certain conditions and plays higher performance than the x86 architecture processors in the same sector.

It can be said that Fang Xingdong has created the core idea of ​​this C2 processor. It is basically the same as the arm architecture that is popular all over the world in the future, and is considered a 16-bit streamlined version of arm.

At the end of the file, Fang Xingdong gave a brief introduction to the design reference of the C2 processor and the mos6502 processor. The 6502 processor, which was launched in the 1970s, was the fastest processor in the world at that time. Because it used a streamlined instruction set to control the processor's work, the 6502's speed exceeded all processors using complex instruction set architectures.

The outstanding performance of 6502 not only brought a huge revolution to personal computers, but also has a wide range of applications in all walks of life. The newly emerging TV game industry, TVGame, has used 6502 chips as the processor of gaming consoles.

When Liang Yuan saw that the 6502 user structure contained Nintendo Enterprise, he couldn't help but laughed secretly. He didn't expect that the c2 processor could actually contact the world-renowned red and white machines.

If the C2 processor is put into production, it should not be difficult to copy Nintendo's red and white machine. I don't know if the counterfeit Nintendo's little bully company has been established now. Liang Yuan thought about it in a little out of touch.

When Liang Yuan turned to the last page of the file and saw that Hughes and Grumman had also used the 6502 processor, he felt a little nervous. The launch time of the 6502 processor happened to be consistent with the development time of the F14 fighter. Whether this thing could be used on the F14 fighter was a little nervous.
