Chapter 128
It's no wonder that Zhang Han's mood is so unstable after listening to Dai Xiang's words. Pen, fun, and www.biquge.info
The technology that intelligently distributes the running thread of a program evenly across the number of cores in each of the phone's CPU is too difficult to master.
It's not just a matter of talking, everyone understands why some CPUs with more cores can't perform better than CPUs with fewer cores? That's because it's not the CPU with a large number of cores that can greatly improve performance.
On the contrary, compared with a CPU with a small number of cores, the architecture of a CPU with a large number of cores is more complex, and there are more details to be processed, and if the control is not good, the CPU will overheat.
When the time comes, there will be more problems, if you can master the technology that Dai Xiang said, then semiconductor merchants like Qualcomm with excellent CPU core quality will not go to heaven sooner.
If you have a Qualcomm CPU with more than ten or twenty cores, the running speed of the mobile phone is not required to take off, and there will be no problem of some mobile phone jamming at all.
This kind of technology that countless semiconductor companies dream of, it is impossible for Huayu Technology Company to have it.
Without a terrible amount of manpower and material resources and enough time, it is simply impossible to develop this technology.
This technology has been accurate to the point of outrageous accuracy in the construction and details of all levels of the mobile phone CPU.
Although the self-developed mericpu is said to be independent research, it does not mean that everything is independently researched and designed.
Here's an example
Looking at all the current mobile phone processors, they basically use the ARVX architecture of reduced instructions, which we can think of as bricks for building a house.
The mobile phone processors built by it are divided into two categories: public and autonomous.
The so-called IP cores designed by public and licensed ARM, such as Cortex-53/A72, after the manufacturer obtains such authorization, only needs to select the number of cores according to their own needs, and the bus interconnection and cache basically complete the CPU design.
It's like it gives you a few sets of fixed construction drawings at the same time, we just need to build a house according to the existing drawings according to the needs, and the difference between each house is mainly in terms of area and decoration.
The autonomous processor solution is to license the ARM architecture, such as ARMv7/ARMV8, and after obtaining these instruction set architectures, the vendor has to design the core by itself, and then complete the construction of the entire CPU part.
The MERI, which it is researching today, as well as most of the chips of Apple and Qualcomm, are the products of this solution.
In layman's terms, they only need bricks, and they come exactly how to build and decorate the house.
In addition, the research and development of self-processing can reduce the losses caused by some uncertainties.
For example, in 2015, when most mobile phone manufacturers were troubled by the heating problem of Xiaolong 810, Samsung used its own processor to watch the fire from the other side.
Although the public version of the CPU solution is more time-saving, labor-saving, and cost-saving, it is easier to be controlled by others, and the independent solution is flexible.
It's just that the transition from the public version to the independent version is a long and extremely expensive process, and the representative brand that has completed this process is Samsung, and its own Xiaomi has been getting better and better over the years.
Only then did the funds and energy be invested in the research and development of independent CPUs, but it took a lot of time and a lot of money, and the performance of the final MERI was also limited, and the gap between the current trendy CPUs on the market was not a little bit.
The intelligent auxiliary chip introduced by Dai Xiang today can not only greatly improve the performance of the CPU, but also once this technology is mastered, it will be able to play a key role in the research and development of independent CPU.
But this kind of technology, Huayu Technology alone can have it now? Don't be funny.
Another problem is that even if you Huayu Technology can manufacture such an auxiliary chip, there must be some instruction architecture adjustments between the chip and the CPU.
At the very least, the two should be fully compatible.
But in this way, the secrets of the internal structure of the CPU will be revealed to the other party, so who wants to?
Of course, if you Huayu Technology is willing to exchange this technology with us, our Xiaomi company will definitely have no opinion.
Zhang Han said: "Mr. Dai Xiang, your introduction is perfect, even if all the functions you said about this intelligent assistance chip are practical, but about the compatibility of the chip with our meri, how do you deal with it?" ”
Even if you buy a car, a new car has a run-in period, and if the chip and CPU are not compatible with the run-in, then there will definitely be problems.
Dai Xiang said: "I mentioned before, the core of our intelligent assistance chip is the use of DG system coding, about compatibility, the intelligent core will have its own computing, compatibility in this aspect, there is no need to worry at all, for example, our DG system has not been for a certain brand of mobile phone out of a special flash package, but the original ecological DG system no matter which brand of mobile phone it is equipped with, it can play a perfect role, there is no incompatibility problem. ”
His own doubts were resolved by Dai Xiang, Zhang Han continued: "Even if the two are used together, don't worry, what I want to say is that since your company has mastered this technology, it must have reached a new level of research and understanding of the core of the architecture of mobile phone CPU, why does your company not independently develop CPU, but to cooperate with our Xiaomi company?" ”
These words, of course, are the words that Zhang Han and others had prepared, but as a technician, he is responsible for pointing out the technical loopholes of others.
This kind of contest between words is from Jia Feifei, a girl, but Zhang Han, who is determined to perform in front of his own boss, is obviously stealing words.
Didn't you see Jia Feifei sitting next to him with a depressed expression? If you want to perform, if you want to steal the show, it's not like this!
Hearing Zhang Han's questioning, Dai Xiang said lightly: "I'm sorry, I have nothing to say about this, it's not my duty." ”
Dai Xiang is right, he is only responsible for the usual scientific and technological research, this kind of business development is not his responsibility, what is the general research? How much money and manpower to invest is a decision for Qin Yu.
Deng Chuyin, who is the head of the company's affairs and a part-time secretary of Qin Yu, said: "Our Huayu Technology is still in the development stage, and we do not have the financial strength and energy to develop our own CPU. ”
"Since Miss Deng Chuyin said so, I still have a question." Deng Chuyin's words were perfunctory in Zhang Han's ears, and they were completely insincere.
He felt that this was likely an opportunity to seize the other party's loopholes and expose the scam.
Zhang Han continued: "Since your company does not have the strength to independently develop CPUs for the time being, how can the technology and manufacturing of intelligent auxiliary chips be completed?" The manufacture of this kind of chip is not as simple as independent research and development of CPUs, but more difficult and complex. (To be continued.) )
