It is an indisputable fact that Loongson Company is too small in scale and seriously short of manpower, and there are even fewer full-time engineers engaged in development work.
In view of this situation, Godson should follow the example of ARM's early weakness (only a fool would expect hundreds of engineers to really beat tens of thousands of engineers of Intel AMD). Loongson Company voluntarily gave up developing specific chip products, concentrated on developing a new generation of ip cores, effectively improved the performance of the new generation of ip cores, and then authorized the ip cores to other companies to develop specific chip products.
At present, many countries, including China, are aware that over-reliance on the products of Intel and AMD in the United States will lead to huge loopholes in national security. I want to get rid of it, but I can't handle it myself. At this time, if a company can sell ip cores and help these countries launch their own computer chips as soon as possible to balance the influence of Intel and AMD, I believe many countries will be optimistic. There are really too many countries like Russia, India, South Korea and Europe that want to get rid of Intel and AMD in the United States.
In China, ip core can be licensed to Huawei, Lenovo, Inspur, Ziguang and other companies. In this way, the research and development personnel of Loongson related products have rapidly grown to hundreds of thousands of engineers, and the related employees have reached millions. This is not a dream at all.
Although the performance is not as good as Intel's, it is truly self-controllable, and it is a pure Chinese core.
First, the autonomy and controllability of Godson.
Loongson's real project was probably 200 1, and it was done in an autonomous and controllable direction at that time, so we chose MIPS architecture, bought it directly, and others stopped using it, not the so-called authorization, unlike ARM.
After buying MIPS architecture, Loongson team also expanded the instruction set. It can be said that Godson originated from MIPS, but it was born out of MIPS. From the beginning of the architecture, it is an independent and controllable Chinese core, which is a pure Chinese core.
Because of this, Godson is widely used in government, military, finance, education and other industries. It requires confidentiality and attaches great importance to security and controllability.
Second, the performance of the godson
For a chip, it is natural to consider performance. At present, compared with intel, the performance of Godson does have a gap of about 3-5 years, so individual consumers have no perception of Godson, because Godson is not for personal consumption, because this field likes to "run a score", and naturally Godson is difficult to be recognized.
More importantly, in the field of personal consumption, the ecological requirements are very high. At present, windows can only be installed on intel\AMD chips with X86 architecture, and it does not support Loongson, so there are very few notebooks and desktops using Loongson.
Third, the significance of godson
In addition, at present, many people have misunderstandings about Loongson, thinking that the performance of this chip is not good, and it relies entirely on government-subsidized goods. In fact, it is not. The state stopped subsidizing Godson a long time ago.
Godson is a commercial activity now, and it is entirely responsible for its own profits and losses. In 20 14 years, Loongson made a profit, and in 20 19 years, it made a profit 10 billion. Over the years, the tax paid by Loongson has already exceeded the subsidy given by the government. Don't treat it as cheating.
Once Loongson succeeds, it will truly free China Core from external dependence. After all, ARM still relies on ARM architecture, but Loongson relies on nothing. It is completely 100% pure Chinese core, which is of great significance and deserves your support.
Godson is based on MIPS instruction set, and has been permanently authorized by relevant instruction sets. It can be said that Godson is not stuck in intellectual property rights such as instruction set, but because MIPS instruction set has no place in the current market, and its application field is limited, at least in the consumer market, with little hope. The PC in the consumer market is mainly a processor with X86 architecture. Mobile phones and other mid-range processors are mainly ARM processors, leaving little room for Godson. Although many people say that the performance of Loongson is as good as some Intel products, or as good as AMD excavators, because of the different architecture, this comparison is actually of little significance to ordinary users, because at present, ordinary consumers have poor ecological support for Loongson. Even if they can run Windows systems, they are simulated, and their performance will naturally be reduced.
Although Loongson has no improvement in the consumer mass market, it can still develop slowly in some sub-sectors, and with Loongson technology in hand, at least the problem of yes or no is solved. In the face of foreign competition, it is emboldened, and in the R&D and application development process of Loongson, it has also cultivated its own talents, so in the long run, the significance of Loongson is not small, so the initial development of Loongson mainly depends on government support. Later, Godson began to be responsible for its own profits and losses. By 20 15, it is said that it has started to make a profit, which is still very good. It is a shame to erase the history of Hanxin in those years. Of course, many people still question Loongson, probably because Hanxin had a great negative impact in those years.
Of course, many people will compare ARM and MIPS because they are both processors with reduced instruction sets. Of course, there are many differences between the two, but MIPS is not sensitive to business and missed the wave of mobilization. Therefore, although MIPS appeared earlier than ARM and its performance was not lost to ARM at first, the development of MIPS is not ideal in recent years, but ARM has developed rapidly in recent years. MIPS are dismantled and then sold, basically GG. As for whether MIPS will have a chance in the future, it is difficult at present, but we still hope that Godson will develop in the future.
It can be said that Godson can recover the chip's autonomy and controllability in military applications.
20 15 in March, a new generation of navigation satellite I 1-S (the first star of Beidou-3) developed by Chinese Academy of Sciences used the domestic "Godson" central processing unit (CPU) for the first time. Every Beidou navigation satellite launched later carried a large number of godsons. Besides CPU, the most typical application of these godsons is reconfigurable technology. In other words, the software of the satellite in orbit can be reconstructed at any time through ground injection, which greatly improves the survivability of the software. From the five-year practical application, the on-orbit performance of Loongson 1E and Loongson 1F is still relatively good, and the processing capacity and reliability are the same as those of imported CPU, of course, the price will be half that of imported CPU.
Godson was developed by Beijing Institute of Computer Science, China Academy of Sciences. Godson was founded with only one goal, that is, Intel, the world's first chip empire. However, there are many military applications of Godson at present, and there is still a long way to go for commercial popularization.
The most promising, most difficult and most independent domestic processor has been concerned about Loongson 15- 16 years. At present, the 3A5000CPU that sends streaming media is expected to run to 2.5GHz for 30 minutes (transferred from Zhihu: 20 17, AMD uses gcc4.6 compiler to optimize the parameter -o2 at 3.4G, and the test values of the third generation CPU spec int 06 are divided into: pile driver. Excavator19.2; Ryzen3 1.5) looks good.
Godson design team is one of the most solid teams in China. The goal of Godson boss Hu is to have something different from other CPU in China in the world, catch the express train of the existing mature ecosystem and develop Godson at a high speed. It is necessary to build a third software system that is not restricted by the external environment through self-built ecology (the forecast scores of individual manufacturers are shown in the figure).
Introduction of godson
For a long time, because of the Hanxin scam and possible intentional confusion, many people either don't understand Loongson or misunderstand Loongson, and some people think Loongson is also a scam because they don't see Loongson CPU appearing on ordinary computers. On this issue, I would like to briefly introduce Loongson here.
Godson team:
The Loongson team was initiated by Hu Yu, a researcher at Institute of Computing, China Academy of Sciences, on 200 1. In 2002, it was officially approved and received an R&D fund of RMB 5 million. Before the Loongson team was established in 20 10, there was a total of 500 million yuan of state funds, compared with the R&D investment of Intel Corporation in 20 15. Strangely, Loongson stopped taking support funds from 20 1 1, and only took a total of 2.5 million yuan from the Beijing Municipal Government and other public and private institutions and enterprises.
Godson's instruction set:
At the beginning, Godson directly adopted MIPS instruction set, and bought the permanent license of 527 instructions of MIPS instruction set at a low price during the financial crisis. Later, it was revised and added to the instruction 1907 according to my own plan, so now it is loogISA with independent intellectual property rights, and it can no longer be called MIPS instruction set. The basic situation of the 1907 instruction is as follows:
Instructions from MIPS:
2 16 MIPS basic instruction, permanent authorization;
3 1 1 DSP instruction, granting permanent authorization.
Godson autonomous teaching:
MIPS basic instruction extension-148 loongext; ;
Virtual machine extension -5 loongVM instruction;
Binary translation extension-213 loongbt; ;
Vector instruction extension-10 14 loongSIMD.
Godson's current model name:
Godson 1 series: for special and embedded applications respectively;
Godson 2 series: used for high-end embedded, industrial control, special applications, servers and desktops;
Godson 3 series: used for PC, server and advanced special applications, in which 3A is quad-core, 3B is not less than 3A, and can be multi-connected (usually used for servers).
Godson 7: At present, it is positioned as a bridge chip, that is, a north-south bridge chip. There is only one godson 7A- 1000, and the first GPU developed by godson is integrated. It is estimated that its graphic performance will not be better than that of the motherboard integrated display ten years ago, but at least it is ok for ordinary daily applications. Moreover, the bridge chip supports independent display, and the performance can be improved by using NVIDIA or AMD graphics cards. Godson is cooperating with NVIDIA.
Godson's performance:
20 15 godson 3A-2000 quad-core CPU single-core performance test based on modified kernel GS464E, manufactured by domestic 40nm low-speed process, scored 6-7 points in 2006, which is about 3 times that of GS464 single-core. 20 16 year's highest frequency 1.5GHz Loongson 3A-3000 test SPEC CPU2006 single-core score 1 1, quad-core score 36. That is to say, under the SPEC CPU2006 test, the Loongson GS464E core scored 7 points per GHz, which was different from AMD and Intel by 10.
Loongson 3A/B-4000 released on February 24th, 20 19, based on the newly developed GS464V kernel, the main frequency was increased to 2.0GHz, and the score was 10, so the score was 2 1 minute, which was close to AMD's excavator CPU two years ago, and the difference was 30~40 with the mainstream scores of Intel and AMD.
Godson management:
Of course, it is impossible for Microsoft and Google to be compatible with Loongson. So although Loongson has installed and run WindowsXP through the binary simulation of X86 instructions, large-scale software and professional software (such as PS, stocks, games, etc. ) can't be used. As a result, Loongson can't use Windows and Android normally, so Loongson can't enter the consumer industry at present, and ordinary users naturally can't see the Loongson processor.
Therefore, after the Loongson team left the Chinese Academy of Sciences on 20 10 to set up Loongson Company to be responsible for its own profits and losses, it began to exist with the angel investment of nearly RMB 200 million from the Beijing Municipal Government, starting from the low-end embedded field and expanding to the industry field and special and customized fields. After all, as an enterprise, it is not ideal to survive, but Loongson has done a good job in the industry. From network servers, storage servers, anti-radiation processors for satellites, to customized computers, set-top boxes, TV CPUs, military command and control systems, high-temperature and high-pressure special processors, to low-end embedding such as traffic lights and charging piles, and other application scenarios are being done, and services such as software are also being done.
20 15, Loongson turned losses into profits. In addition to the continuous growth of embedded and special services, Loongson desktop applications have also begun to grow. In 20 18, Godson desktop CPU sold 50,000 pieces, accounting for 0. 1% of the desktop CPU market share in China. In 20 19, the sales of desktop CPU in Loongson CPU reached 500,000 pieces, accounting for1%of the domestic desktop CPU market share;
Nonsense, the old Godson couldn't even see the shadow of Intel. In 2020, Godson can see the back of Intel's head in performance and form a system locally. It should be the first domestic enterprise in the industry market, and then it will expand its business and gradually enter the consumer field, and strive to compete with Intel, AMD and IBM on the same stage after 2030.
Note: If you are interested, you can search for "Godson" in Mile Mile. You can find the speech "From Inside to Outside, Loongson Development and Industrial Ecological Construction" by Dr. 20 19 of Shandong University Loongson Company and the speech by Chief Engineer Hu of Sun Yat-sen University Loongson Company 20 19. 20 19 12 24. Hu's speech at Loongson conference contains information beyond ordinary imagination, such as: Loongson equipment will be used in civil servants on a large scale through local pilot projects in the past two years; Godson has been spreading in the field of military equipment, and has also made a digital earth for the army. According to the previous information (officially speaking, it does not involve leaking secrets), the military scope of Loongson at least includes command and control, missile guidance, precise positioning, tank control or fire control system, and military information system; Wait a minute.
It must exist.
Godson must exist, other people's stones are unreliable!
Only by learning from excellent enterprises with an open mind and insisting on independence can we develop confidently.
Supporting domestic production shows that domestic chips have reached a higher level.
