At the moment when a primitive man looked up at the starry sky, the early warning system of the danger eliminator began to alarm. People were very surprised, and the troubleshooter explained, "Is it hard to understand? When life realizes the existence of the mystery of the universe, it is only one step away from its final solution. For example, it took life on earth more than 4 billion years to realize the existence of the mystery of the universe for the first time, and that moment was less than 400 thousand years since you built Einstein's equator, and the most critical acceleration period of this process was less than 500 years. If the primitive man stared at the universe for a few minutes and saw a gem, then your so-called whole human civilization just bent down to pick it up. "

-Liu's Wen Chao Dao

More than 100,000 years ago, in the night of a guardian tribe, a primitive man looked up and saw the bright starry sky. The germination of human exploration skill tree is rooted in the genes of ethnic groups.

There is also a question in Zhihu: What are the examples of "misplaced skill trees" in history? Thus, a question from the depths of the soul was born: which has a more profound impact on human society, natural science and technology, political system or economic system? Looking back at the crooked skills in those years, some people say that all molecules must have an Egyptian score of 1, some people say that Mayan civilization is crazy about "blood sacrifice" skills, and some people say that it is crazy about mobile phones and computers.

I agree that the biggest problem of human skill tree is not the wrong direction, but the underdevelopment. In the romantic period, it used to be owned by all mankind. Satellite launch, Apollo landing on the moon ... Everyone looked at the sea of stars. However, after the end of the cold war, it did not produce huge direct benefits like Columbus' navigation, and it was limited by the existing level of science and technology. Humans have not slackened off the aerospace industry, focusing on lighting up the Internet and integrated circuit design industries, but they are at a loss to unlock the skill tree of interstellar travel.

In fact, aside from those distant imaginations, we need to see the necessity of the existing skill tree.

Games that are regarded as killing time not only enrich people's entertainment life, but also promote the development of chip industry. In order to make more realistic game pictures, GDDR interface and GPU performance are constantly upgraded.

With the continuous explosion of information flow on the Internet, based on Sigmund Hall effect, the next generation storage technology can make a single chip of about 200 square millimeters realize TB-level storage.

The cutting-edge technology can be used to solve the most livelihood problems. We should not only look up at the starry sky, but also look down to earth.

Not long ago, Sina Finance introduced a number of domestic high-speed interface IPS, all independently developed by Innosilicon, including MIPIDSI &；; IP such as CSI/LVDS combined physical layer, DDR 4/3/LPDDR 4/3 combined physical layer, etc. These comboips meet the multi-standard compatibility index, can meet the low power consumption and small area mode, and realize commercial mass production.

The breakthrough lies in the 14nm Finfet process based on SMIC's local OEM, and SMIC Innosilicon has become the first in the domestic industry. This has also changed the mode of relying on foreign technology, making the chip ip completely autonomous and controllable.

Among them, Innosilicon's GDDR6 IP scheme has attracted much attention. In addition to graphics cards, it can also be used in important fields such as AI artificial intelligence, autonomous driving, data center, graphics and high-performance computing.

Just like the initial intention of human beings when they first look up at the starry sky, from the research and development of chips to intelligence and informationization, the purpose of human beings to constantly light up the skill tree has always been to use technology to make everyone's life better.
