Chapter 210 Mobile phone SOC developed successfully

"Ruida, are we moving to Shijia Hutong tonight?"

"All the exams have been completed, and the school is about to go on winter vacation. We have nothing to do at Peking University, so we might as well move back home as soon as possible."

In the past semester, Qiao Ruida and Du Qingqing lived in the school dormitory most of the time. Only on weekends or holidays, they went to the courtyard house in Shijia Hutong to spend two days together.

"Then when will we go back to our hometown for the New Year this year?" Du Qingqing asked.

Qiao Ruida thought for a while and replied: "The Chinese New Year is relatively early this year. New Year's Eve is on the 22nd, and there is only one week left. During this week, we will make a summary of some of the work and projects we have done in 11, and We have to make a development plan for the coming year. We have to hold an annual meeting before the end of the year. Time is tight. How about we go back on New Year’s Eve. Anyway, Decheng City is not that far away, just three or four drives away. You can get there in an hour.”

"Okay, everything is up to you. By the way, will Reda Technology and Reda Network hold this year's annual meeting together?"

"Yes, they will be held together. Now the two companies have just split up and are still working together. It would be too strange to hold the annual meeting separately."

Du Qingqing nodded and said: "That's right. It's better to hold the annual meeting together this year. It's more lively with more people. It's just that the two companies combined have at least 10,000 employees, so they can accommodate a meeting with so many people. Isn’t it difficult to find the venue?”

"It's really hard to find this one, but I heard that Sister Liu found a convention and exhibition center in Changping that can accommodate more than 15,000 people. It should be enough."

The two walked forward while chatting, and soon came to the downstairs of the girls' dormitory. Du Qingqing returned to the dormitory, packed some clothes and daily necessities, packed it in the suitcase, and took it downstairs to meet Qiao Ruida. Qiao Ruida took the suitcase from her girlfriend's hand and walked directly outside the school.

"Hey, Ruida, are you going in the wrong direction? Why don't you go back to the dormitory and pack your things?"

Qiao Ruida shook her head and said, "I packed up my clothes, notebooks and other things last night and put them in the car. Now we can just leave."

That night, Qiao Ruida and Du Qingqing spent a warm night in the courtyard. The two of them were still in love. They hadn't tasted the smell of meat for a week, and now they smelled the fishy smell again. Naturally, they were particularly obsessed with each other. As a result, Qiao Ruida and Du Qingqing got up one after another at three o'clock in the morning.

After breakfast, Qiao Ruida drove Du Qingqing and rushed to Hailong Building together. After arriving at Ruida Technology Company, Du Qingqing went directly to the sales department, while Qiao Ruida came to the R&D department to learn about the latest R&D progress. The chip design drawings of Jiuzhou Mobile SOC have been updated to nine versions, and the tape-out test has been carried out three times. The chip products obtained from the last tape-out can be installed and run normally, and the power consumption and heat generation are controlled within normal limits. Basically, the basic functions can be realized. In terms of performance, it is much better than the Qualcomm Snapdragon chip used in the Ruida first-generation mobile phone. Only in terms of GPU compatibility, there are still some problems when running some test software or game software. , there will be some texture errors and confusion of light and shadow.

Qiao Ruida operated the mobile phone engineering machine in her hand and played the popular "Angry Birds" game. She passed all the levels until a large number of mosaics appeared on the game interface. Then she stopped and said, "Have you found the problem? It's a hardware problem. , or is it a software problem?”

Xiao Jingsheng, the R&D manager sitting next to Qiao Ruida, looked away from the engineering machine interface and said: "There are no problems with the Kaitian system and Jiuzhou chip we developed. The problem lies in the graphics card driver. Our Jiuzhou chip has The architecture of the GPU module used is so new that no mature driver can be found at all. The driver currently installed on the engineering machine was temporarily created by us in the past two days, and it is inevitable that there will be some bugs. I have organized People, start writing a fully functional GPU driver, which should be able to solve the problem of game texture errors before the Chinese New Year."

Qiao Ruida nodded with satisfaction and continued to ask: "What about the power consumption and heat generation of the chip? Is it any better than the Qualcomm Snapdragon chip?"

Xiao Jingsheng said quite proudly: "Of course there is progress. The Jiuzhou No. 28 chip we designed uses the latest ARM architecture and is produced using the 8260nm process. Compared with the Snapdragon MSM8260 used in Reda's first-generation mobile phones, it is simply not the same. Products of the same dimension. The Snapdragon MSM28 is only a dual-core chip, while our Jiuzhou-60 is an octa-core chip. The architecture is also much more advanced. The performance is expected to be at least eight times worse, but the power consumption and heat generation are not much different. This is the advantage of the latest nm production process. In terms of graphics display performance, the running score has at least quadrupled, and the actual game performance is also much better. In the past, mobile games could only run more than frames, but on this engineering machine, It can also run above frames. Except for the occasional blurry screen and texture errors, this engineering machine is basically perfect."

Qiao Ruida played with the engineer phone in her hand and couldn't help but shook her head and said: "Is it perfect? ​​Not necessarily! In my opinion, this phone has many shortcomings, such as the screen is not full screen, the maximum charging power is only 18W, and there is no wireless Charging function, camera pixels are too low, etc. It’s not that easy to make a perfect mobile phone.”

"Okay, boss, you are right. This engineering machine is indeed not perfect. By the way, boss, yesterday BOE sent someone a package, saying that the water drop screen for the mobile phone ordered by our company has been successfully developed. Send it Got a few samples.”

Hearing the news of the successful development of the water drop screen, Qiao Ruida was overjoyed and asked hurriedly: "Have you opened the package and tested the screen?"

"The package has been unpacked, and we have also seen the water drop screen. If installed on a mobile phone, it will be very beautiful. However, the wiring of the water drop screen is different from the screen wiring used on engineering machines today, and the mobile phone motherboard needs to be reworked. Design can only be connected to testing." Seeing that Qiao Ruida was so interested in the new screen, Jamel Xiao immediately answered truthfully.

"Then quickly design the motherboard and test the water drop screen. Kyushu chip + Kaitian system + water drop full screen. With these three magic weapons, our Reda second-generation mobile phone is ready. When it is released, it will definitely be amazing. reach all consumers and shock a large number of peers.”

An hour later, a brand new mobile phone engineering machine equipped with a water drop full screen was assembled. Due to the rush of time, this mobile phone does not have a front camera, earpiece and proximity sensor, and can only be connected outside with wires.
