After carefully reviewing all the information, Liang Yuan sat on the sofa and pondered. After a long time, he slowly said: "Old Su, what is the difference between the processor you have developed and this C2?"

Su Liangyu thought for a while and said: "In terms of architecture, the C2 processor is 16-bit processors than the 7x series processors developed by the Science and Technology Park. The main frequency of the 7x processor will be slightly higher than that of the C2. However, the emergence of Risc technology is many years later than that of Cisc technology. Innately, Risc technology is much more advanced than Cisc technology. At the same frequency, the running speed of the Risc architecture processor is 2-4 times faster than that of the Cisc architecture processor. It can be said that the running speed of the C2 is still far higher than that of the 7x processor."

The 6x chip currently produced in the Science and Technology Park is equivalent to the 8086 processor released by Intel in the mid-1970s, and the 7x series currently under development is similar to the 80186 launched in the late 1970s.

Liang Yuan was very curious about Su Liangyu's ability to develop 80186-level chips at the beginning. In Liang Yuan's memory, the Republic's processor development capabilities were so bad. Therefore, the 80186 processor, which opened the door to the personal computer era, seemed very profound in Liang Yuan's eyes.

Su Liangyu was very funny at Liang Yuan's awe-inspiring attitude. He once told Liang Yuan that the ability to develop integrated circuits in China is not bad at all, like the large-capacity Han card sold by Lenovo, among which the chip level used to process Chinese characters has reached the level of 80186 chips.

Lenovo is developing a new generation of Han cards that use ultra-large-scale integrated circuits (Note 1) design, which is close to the level of 80286 chips in terms of hardware.

During the process of converting processors from military to civilian use, the first large-scale commercial application was exactly the large-scale application in the field of word processing. Wang'an Computer Company seized this opportunity to take advantage of the situation. It can be said that the 80186-level chip was not a problem at all for the domestic level at that time.

"However, processors using cisc architecture on the market still survive well. The root cause is that risc architecture has several relatively large defects, generally speaking software with the same function. The source code that software engineers need to write on risc processors is much larger than the same software running on cisc processors." Su Liangyu continued.

"In terms of how the processor controls the device, the cisc processor can achieve the control purpose with software, and the risc processor must use physical wiring to connect the processor and various parts of the device. This greatly increases the difficulty and cost of interaction between the human-machine using the risc processor."

Su Liangyu talked for a long time, and looked at Liang Yuan's still confused appearance, and sighed helplessly. He smiled and said, "It seems that Xiaoyuan is not very interested in this purely technical thing. Let me give you a practical example."

"The Science and Technology Park currently uses cisc-framed 6x series microprocessors. When developing the control system of leafless electric fans, we spent five months and invested more than 100 people. We successfully developed the control system."

"If we change to a Risc architecture processor, we will have to invest at least 300 people and take a year to develop the entire control system."

"For end users, the risc processor has unparalleled advantages. For software engineers who develop various programs for the risc processor, the risc processor is a disaster. Software with the same function can invest at least three to five times the manpower and material resources in the risc architecture. So, does Xiaoyuan have a more intuitive understanding?"

After listening to Su Liangyu's actual example, Liang Yuan suddenly realized that no wonder Intel in later generations unified the world and defeated companies such as ibm and Motorola and lost their armor and lost their fortunes.

In the development of processors, companies such as ibm and Motorola have chosen more advanced architecture and superior performance. In terms of processor replacement time, they are naturally weaker than Intel, which uses cisc technology.

As a result, Intel, a chip rogue, seized the long-term development time of Risc processors and invested a lot of weaknesses, and used the chip sea tactic of releasing new chips to drag the Risc camp to activate the chip.

Ignorance computer novices don’t know that each generation of RISC processors is three or four times faster than the x86 rag of the same era. Seeing Intel frequently refreshing the number of processors at the highest frequency, they will only think that this company has advanced technology and superb level.

In the competition for processors of personal computers, Intel uses the concept of operating popular fashion to operate the updates of the entire processor market, and has staged a tragic comedy of bad money driving good money.

"Old Su, what you mean is that putting aside all commercial factors, the C2 processor itself is more advanced than the 7x series processor we are developing, right?" Liang Yuan confirmed the meaning in Su Liangyu's words again.

Su Liangyu nodded and said, "As far as the processor itself is concerned, the arm architecture using Risc technology is much better than the x86 architecture using Cisc technology. However, the processor has always achieved its control functions through software. The existence of simple hardware is meaningless. Its huge weakness in software development is enough to offset the technical advantages of the Risc architecture."

Liang Yuan gently tapped the handrail of the sofa with his fingers, and then continued after a while: "Lao Su, we have a natural disadvantage in the process technology of integrated circuits. Foreign chip manufacturing processes have popularized 1 micron manufacturing technology. For us, a 5 micron production line still requires a lot of effort to master the technology. The gap between them should be 3-4 generations."

"When I just read the information, I found that the number of core transistors of c2 is only 20,000, and the number of 7x series transistors we are developing now should be 70,000."

"Justice just said that the C2 processor using Risc technology will probably be two to four times faster than the 7x series we are developing. There is a transistor difference of nearly four times between the C2 processor and the 7x processor. Can it be understood that when we are lagging behind in process technology, we can also get a processor close to mainstream performance."

Su Liangyu nodded with a smile and said, "Although things are not that simple, Xiaoyuan's words are not wrong. However, Xiaoyuan has to make a long time to replace the processor and needs preparations for large-scale developers."

Liang Yuan laughed and said, "Although we can find many companies with advanced manufacturing processes to produce processors for us, unfortunately I have had enough of Huajing's virtue. As for the personnel, Lao Su, there is no need to worry. The computer department of Dongda University has always had a good foundation. It should be fine if we jointly set up a computer branch with Dongda University."

"But it's a pity that Lao Su did in the early work on the 7x series." Liang Yuan sighed.

"It cannot be said to be a waste. If we do not plan to use the x86 architecture for a long time, we do not need to consider the future development potential. It will be easier to avoid patents on the x86 architecture now. The 7x series can speed up the development speed."

"We still retain the processor of the x86 architecture. Its easy to develop feature is very suitable for cross-industry industrial control processors. In the future, we can use the x86 architecture as a dedicated series of industrial control processors, without considering performance improvements, and only work on stability and ease of use."

Liang Yuan also vaguely remembers that Intel's 486-level processors are still being produced in the new century, so he naturally agrees with Su Liangyu's suggestion.

After getting the C2 processor done, Liang Yuan did not decide whether to implement the plan to renovate the production line suggested by Shengjing Science Instrument Factory. After irresponsible, he told Su Liangyu that he would consider it carefully, Liang Yuan left the Science and Technology Park with two little girls.

The two little girls had long been drowsy by various extremely professional terms. Ning Wanjia could be better. Although her eyes were full of confusion, she could still look like I was listening carefully. Ning Wanfei was really yawning and was almost lying on the sofa in the office to sleep.

The three of them left the gate of the Science and Technology Park. A loli breathed a long sigh and said, "I finally came out. I'm going to fall asleep."

Liang Yuan looked at the two loli with straight hair without wearing a headdress and laughed and said, "I just found a good way to distinguish you."

The two little girls stared at each other in surprise and said, "Xiaoyuan, you are lying."

"It must be Feifei who has been yawning just now." Liang Yuan said affirmatively.

The yawning loli curled her lips and said, "What's the point? We can make him fail at will. Xiaoyuan also knows how difficult it was for my sister just now. Tell me how to compensate for my sister's losses."

At this time, Liang Yuan was able to guess the two little girls and said with a smile: "Feifei has decided, I have nothing else to do today."

"Even if I go to drive a bumper car for you for a day, I will never regret it." Liang Yuan made a bitter and revengeful expression.

"But Feifei, should you tie your hair first?" Liang Yuan asked with a small heart.

All morning, Liang Yuan was tortured by two identical little girls and was dying of ecstasy. It was very rare for others to see twins who looked the same.

For Liang Yuan, who has been mingling with two little girls since he was a child, this is simply a very bad thing. Not to mention being pinched at any time, after kicking, seeing two small faces with exactly the same innocent expression, even if they were chatting normally, it would be extremely difficult.

The Loli, who had a disdainful expression on her face just now, turned into a hesitant expression in a blink of an eye. She reached out and poked the Loli beside her and asked, "Feifei, what do you think of Xiaoyuan's suggestions?"

"But, Feifei, Xiaoyuan is asking you." The loli who was stabbed said hesitantly.

Liang Yuan looked at the two little girls who had become exactly the same in the blink of an eye, and suddenly felt that he was about to go crazy.
