When it comes to chips, the first thing that comes to mind is definitely about the chips that are restricted by the United States in China, but such chips are generally more suitable for everyone's equipment like mobile phones.
In fact, the chip is divided into different types according to the standard, and in it, there is a more special chip, which is mainly used in the Beidou satellite CPU, and its price is still very high, do you know what its name is called?
The name of this chip is called the aerospace-class chip, the most expensive chip chip in the world before, is from the FPGA chip of Xilinx Company in the United States, and this chip has reached a high price of 5 million before, if it is now, the price will only be more expensive.
In this regard, until now China has made a major breakthrough in this regard, that is, China's own space-level chip has been applied to China's own satellite system.
Lin Baojun, chief designer of China's Beidou-3, said that the price of this type of chip used in the CPU of China's Beidou satellite has reached 9 million yuan, and such a price has been much cheaper than in the past.
Knowing that the price of this chip has risen very rapidly, especially in our country, this chip is very high, then for this matter, China has been on the mobile phone chip by foreign countries to give the neck, why can it now get 9 million Beidou chips?
In fact, the first thing we need to know is that this chip is completely different from the chip in the usual mobile phone, especially the most basic requirement for this chip is that it needs to have a high radiation resistance, because the environment used by this chip needs to contact space, so in such a situation, if it does not have a high radiation resistance, then it is equivalent to having no effect at all.
And in the past use, there have been nearly 40 satellites that have failed thousands of times, most of which are due to problems caused by space radiation, so if the chip does not have a high radiation resistance, it is equivalent to a state of scrap.
Therefore, for the construction of aerospace-level chips now, the requirements for radiation resistance will be higher, and because of this, the price increase in research and development in this area will also be very high.
When the technology was not mature before, the satellite chips used at that time were difficult to resist for some high-energy particles and cosmic rays in space, so it was easy to cause a short circuit inside the chip, and then cause abnormal functions.
In addition, the temperature difference is also a very important factor in its impact, the biggest impact on the spacecraft in the satellite orbit is light, which will make it unevenly heated, and then lead to the existence of temperature differences, so in this case, the chip needs to withstand a temperature difference of nearly 300 degrees, so this is also a huge problem.
However, in summary, these problems, in fact, for our country, the difficulty is not large, the reason why our country is limited by foreign countries in the type of mobile phone chip, is because China is not mature enough for the 5 nanometer chip technology.
However, for the aerospace-level chip, the most important thing is the stability and anti-radiation ability of the technology, in such a situation, the use of relative to the more stable 48 nanometers or more has matured chips, so in this regard, the role of Western countries in the technical blockade of China is not large, and China's grasp of this key in fact is more mature, can be better used in research and development, so that it can develop a fairly good aerospace-grade chip.
Although in the early days, China also relied on certain imports on the CPU, but in Europe and the United States, after the implementation of certain restrictions on aerospace-grade chips, China has begun the introduction of open source code in the design, in order to achieve independent research and development, and the development is still very smooth. Among them, Loongson is a typical case of China's aerospace-level chips, and the series of chips developed by our ministry in 2017, its technical indicators have reached some standards in the United States.
In this way, China has already possessed independent research and development capabilities on the chip, at present, China's Loongson 1E has completed the replacement of chips imported from the United States, and China is developing the next generation of aerospace-grade CPU, and its performance will be higher, if this work is completed, our family can smoothly break the monopoly of Western countries on more high-end aerospace-level chips.
At present, it seems that China has developed very smoothly on this chip, and with the continuous development of China's economy, science and technology, and human beings, I believe that China will be able to develop a more reliable aerospace-level chip and achieve more breakthroughs.
At the same time, there will be greater progress in other types of chips, promoting China's future high-end technology industry to a new course.
