Exited the [Xueba Chat Group] Xiao Jun thought about what he was going to do next.

Due to the fact that the Galaxy Butler helped develop the virtual game engine, Xiao Jun's busy days finally came to an end. After all, he used to be busy not only with the company, busy with classes, but also busy with developing virtual game engines.

Now that he has developed this Galaxy Butler artificial intelligence program, he is equivalent to having a clone.

"As the saying goes, an inch of time is an inch of gold, and it is difficult to buy an inch of time. You still have to cherish your young time. Xiao Jun said with emotion. In short, he doesn't plan to let himself sit idle, now is not the time to sit back and enjoy it!

"My super battery has taken off, and my Galaxy Technology company also has a huge amount of money, it seems that it is time for me to prepare in advance for my future mobile phone company!"

That's right, Xiao Jun plans to take advantage of the time now, why don't you develop a mobile phone chip to play?

What is the most important thing about a mobile phone? That's right, that is the mobile phone chip.

At present, Huaxia needs to import more than 200 billion US dollars of various chips to the West every year, and the total amount of chips imported every year is more than the crude oil imported.

This also illustrates the importance of a mobile phone chip!

Everyone knows that it is not easy to develop a mobile phone chip with superior performance, you don't know how much manpower, material and financial resources to invest, and the chips researched may still not be able to catch up with others. Because chip technology is updated too fast, it is being updated every year!

One generation behind technology, that's a year behind, or even longer!

If you're a few generations behind? You might just have to eat dust forever!

"It seems that it's time for me to save the Huaxia chip market!" Xiao Jun's mood of hard work arose. Since you let someone else earn this chip money, it is better to let him earn it!

"First of all, the mobile phone chip I developed must be easy to process and durable, and the most important thing is that it has superior performance and beats everything!"

Take the first one as an example, if you produce a mobile phone chip with superior performance, but because it is difficult to produce and process, then the final production capacity is low, and you can't even satisfy your own company's mobile phone, so how can you sell it to others?

So, it's important to be easy to process!

Needless to say, durability must be passed, the quality must be passed, as for the superior performance, what should the chip with not superior performance do?

"Since we want to develop our own mobile phone chip (CPU), we can't imitate other people's paths, and we can't rely on other people's technology. Then all things are to innovate and develop their own things!" Xiao Jun said secretly in his heart. This is very important. What's the use of not being able to develop an independent chip?

Take the current well-known Kirin 970 chip in China as an example, it is advertised as a self-developed mobile phone chip.

Of course, this can only deceive the people who eat melons!

What are the 5 major components of mobile phone chips?

1: Architecture

2：GPU

3: Signal processing

4: Communication baseband

5: AI function

First of all, let's talk about what is the architecture? Simpler, architecture = instruction set! Complex, set instructions are conceptually similar to CPU processing various calculations, CPU processing and computing are also small steps converge into big steps, and the results can be obtained after completing the big steps. The instruction set is a subdivision of the steps that the CPU processes various calculations, except that it fixes the various steps as a combination.

If you put the phone chip is a city, there are several industrial areas in it, as well as residential buildings (l1 l2 l3 cache). What the whole city looks like is the architecture of the mobile phone chip, how to connect between the industrial areas is the multi-core architecture of the CPU, and what the industrial area looks like is the architecture of the CPU core.

The architecture is the core of the most important mobile phone chip, but the architecture of this Kirin 970 is not independently developed, but uses the public ARM architecture.

Second, GPU, it is called graphics processor, display core, visual processor, display chip, is a kind of microprocessor that specializes in image computing on personal computers, workstations, game consoles and some mobile devices (such as tablets, smartphones, etc.). The better your GPU, the better your phone's chip performance will definitely be.

The GPU of the Kirin 970 is not independently developed, but uses the Mali series GPU.

Third, signal processing, the Kirin 970 uses Cadence DSP, not independent research and development!

Fourth, the communication baseband, Kirin 970 is a self-developed Balong 750, which is the world's top level in terms of technology.

Fifth, Al, in terms of new functions such as AI, Kirin chips are also leading. The Kirin 970 uses a separate Cambrian NPU chip - that is, an artificial intelligence chip.

But in the end, in summary, there are three of the five cores of a mobile phone chip, which you use from others, not independent research and development, and only two of them independently develop their own things.

Strictly speaking, this Kirin 970 mobile phone chip is just a mobile phone chip made up of other people's parts plus a little bit of your own, and it is not a completely self-developed mobile phone chip!

So Xiao Jun will definitely not do such a thing, he must develop the above five cores by himself!

"So let's start with the architecture first. Xiao Jun thought to himself.

Because he had learned a lot from Halliday before. These include the hardware of the virtual game, the design of the virtual headset, the design of the console of the virtual game, and other equipment.

As far as the virtual game console is concerned, it also has a chip in it!

The processors of Halliday's time were certainly ahead of the current Earth.

Therefore, Xiao Jun currently plans to refer to this virtual game console processor, and then combine the current situation to develop a new chip!

"Architecture, since architecture is so important for a chip, then it must be awesome. ”

"The architecture I designed must be complex and have superior performance!" Because Xiao Jun knows that complex architecture, that is, complex instruction sets, will be more personalized, so it is more difficult to design, because the actions to be completed by each instruction are more complex, but the advantage is high efficiency and fast time. The thin architecture (instruction set) is well designed, but if each action is divided into more steps, it will lead to lower efficiency, slower execution, and more energy consumption if you artificially increase the clock frequency.

"So the algorithm in the set instruction must be fast!" Xiao Jun was proficient in programming before, and he read a lot of books on this subject, and he also learned a lot of knowledge from Halliday.

He is still very clear about these things!
