Chapter 177 NB-Y chip architecture is simply against the sky!(1/2)
Chapter 177 NB-Y chip architecture is simply amazing!
[I was too late last night and I was afraid that I would be discontinued for full attendance. I wrote the last 200 words in a hurry, so I posted it first and rewritten it. If you read it before 12:30 in the morning, you can re-read the last 200 words.]
With the deduction of 500,000 points, a golden light flashed, and several new options popped up in my mind.
Hu Lai was a little surprised that this situation had never happened before.
He looked carefully and several options appeared out of thin air in his mind.
"Ding... You have purchased 14nm chip design drawings. Please select the type of chip architecture you need based on the technology in your current world."
Chip architecture type?
He took a quick look and found five options.
X86 architecture.
ARM architecture.
RISC-V architecture.
MIPS architecture.
NB-Y architecture.
this……
It's a bit hard.
Hu Lai was not very clear about chip professional knowledge, and he was not in a hurry to make a choice if he couldn't figure it out. He quickly quit the system and searched online.
After understanding it, I finally understood a little.
It turns out that when designing a chip, the first thing to do is to determine the chip architecture.
What kind of architecture a chip adopts almost determines the purpose of this chip.
Simply put, for example, the two mainstream chips on the market, one is the CPU chip on the PC side, which is monopolized by Intel and AMD, and both adopt the X86 architecture.
The other type is mobile phone chips, and almost all mobile phone chips adopt ARM architecture.
The RISC-V architecture and MIPS architecture, the former only appeared in 2014. Although it started very late, it is very simple to use and develops quickly because it adopts the modular design concept.
The biggest advantage of RISC-V architecture is that it can modularly select the appropriate instruction set architecture based on specific scenarios.
For example, CPUs specifically used for household appliances, industrial control CPUs, smart wearable devices, and CPUs in some sensors smaller than fingers.
The latter MIPS architecture is mainly used in network devices, such as network routers, etc.
Looking at the computer screen showing information about four mainstream chip architectures, Hu Lai had no time to search for the last NB-Y architecture, and he became interested in the commonly used X86 computer CPU and ARM architecture.
Although I often hear about computer CPUs and mobile phone chips on weekdays, I really don’t know much about the specific differences.
He was reading the information carefully.
The biggest difference between the X86 architecture chip and the ARM architecture chip is performance and energy consumption.
In terms of performance, the X86 architecture adopts a complex instruction set, focusing on high frequency and high performance, which makes the X86 architecture's chip performance powerful and the computing speed is super fast.
And what about ARM architecture chips?
It's exactly the opposite.
The chips of the ARM architecture use a simple instruction set, paying great attention to low frequency and low power consumption. All storage, memory and other performance are set at the beginning of the design, almost no scalability is considered.
The different focus of the two architectures leads to the performance comparison between ARM chips and X86 chips, which is completely a younger brother.
For example, if the Snapdragon 8155 chip used on Phoenix "Qingluan" is compared with the Intel series chips with X86 architecture...
Even if the Snapdragon 8155 is an octa-core processor, its actual performance can only reach 50% of the computing power of the Intel I3 processor.
The Hongguo A15 processor, which is known as the strongest on the surface, is only at the level of the I3 processor in terms of overall performance.
And there are better I5 and I7 on Intel I3 processors...
Seeing this, Hu Lai was a little surprised.
He has always known that the performance of mobile phone chips is worse than that of computer CPUs, but he never expected that the 5-nanometer A15 processor can only perform similarly to the 14-nanometer I3 processor!
That's right, it's the I3 processor with a 14-nanometer process!
Hu Lai continued to watch, and after he finished reading the energy consumption of the two chips, he completely understood.
Although the performance of computer CPUs is far superior to that of mobile phone chips, another very big problem is that they have high energy consumption and high temperature.
For desktop computers and laptops, which originally require power supply to be plugged in, it is naturally not a problem to consume a higher energy. Even if the CPU temperature is high, you can install a radiator to dissipate heat.
but.
How can such a chip be so good if you put it in a mobile phone?
A chip with high energy consumption can run out of the battery of the mobile phone in two hours, and it will get hot as soon as you play with the mobile phone. Who can use it?
and.
The most important thing is that chips like I3 and I5 are too big in size.
An ARM chip is one-tenth of an I3 chip. Every inch of land in a mobile phone cannot accommodate such a large chip size.
so.
In the field of convenient equipment such as mobile phones, the advantages of low frequency and low power consumption of ARM chips are reflected. The chip size is small and can easily meet the problems of heat dissipation, power supply and battery life.
On the basis of solving these problems, you only need to improve performance as much as possible and meet the needs of fixed application occasions.
call--!
Seeing this, Hu Lai suddenly became hot!
Although the X86 chip has problems such as heat dissipation, high energy consumption and large volume, it is!
Are these problems a problem for a new energy vehicle with plenty of space, 75KWH (75KWH), and even a radiator installed?!
If the X86 computer CPU can be used on "Qingluan", then wouldn't the computing power performance be overwhelming?
Hu Lai suppressed his excitement and continued to check the information. If he decided to choose the design drawings for the X86 architecture, then the next step is to consider the production and manufacturing issues!
But when he searched for information online, he suddenly felt overwhelmed.
Not to mention production and manufacturing, Taiji Electric can even produce 3-nanometer I14 processors for Intel, and there is no problem with domestic SMIC producing 14-nanometer I3 processors.
And the most important thing is authorization.
Because the authorization of the X86 architecture is all in Intel's hands, if Phoenix wants to use the X86 architecture to design a chip production, the first step is to obtain Intel's authorization.
Hu Lai sighed slightly, and Intel has clearly refused to sell smart cockpit chips to Phoenix Automobile, not to mention the authorization of the X86 architecture!
It is almost impossible to obtain X86 architecture authorization.
His thoughts returned to the Snapdragon 8155 chip used on Qingluan. Snapdragon 8155 uses the ARM architecture.
"Then you have to choose the ARM architecture!"
This thought came to his mind and couldn't help but think: "ARM architecture won't require authorization, too..."
After he checked online...
Hu Lai: “…%¥&…”
As expected, ARM also needs authorization!
Damn it!
He had never paid so much attention to the chip industry before, and only then did he really understand that it was really difficult for the Yanguo chip industry to develop.
From the bottom layer of chip architecture, the bottom layer of instruction set is completely monopolized by Intel and ARM, followed by chip design software EDA, then the lithography machine, silicon wafer, etc. in the manufacturing process...
This series has been stuck almost all from design to production!
To put it too much, just like the Mao Bear in the north, X86 and ARM have been cut off directly, and you have no choice yet!
Hu Lai is now fully aware of how difficult it is to develop a new chip.
Intel's X86 is probably out of the way, so I can only try it with ARM!
If ARM does not authorize it, even if you purchase 14-nanometer chip design drawings from the system, it will be useless.
After all, no one dares to produce without authorization.
"Hey! Just contact me first."
Hu Lai had plans. Just when he wanted to call Director Zhang and asked him to contact ARM, he suddenly felt something was wrong.
Huh?
wrong!
There are five options in the system, and I just found only four!
There is also an NB-Y architecture that does not query itself!
Hu Lai started to check NB-Y architecture information with a hint of expectation, but after searching on the Internet several times, there was no trace of NB-Y chip architecture information!
It's impossible!
To be continued...
