"Editor's note" Mars chip on the fly at ease after the Hotchips Conference appear questionable, domestic chip technology is really hard to bear responsibility? Author @ Thunder Europe Altman, electronic science and technology, Chinese Academy of Sciences calculation engineer.
Federal Corporation (Phytium Technology) Mars 64-core CPU Hotchips Conference suddenly landed the industry recently, Godson became the second after second landing Hotchips made CPU. This market still receive two contrary voices, one Chinese-made CPU has reached or partially reached the world-class level, Yang Wei out of the country, the other is that it is the lack of control, under the existing scientific research system of lack of honesty and a lie big funds. In my opinion, both views are extreme suspicion, is not desirable, but the other side, these two views cannot be described without reason.
Mars and Xiaomi level?
In a nutshell, Mars and Xiaomi is enough to rank among the top results in domestic first-tier, but from the front to challenge Intel still has a long way to go. Hello Kitty iPhone 6 Case
Editor's Note: Mars ("MARS") core codenamed Xiaomi, Xiaomi core is a typical modern processor micro-architecture, four launches, two floating point units, not long lines and three-level caching solutions.
First of all, take a look at Mars and Xiaomi an excellent side. This is domestic first paragraph ARMv8 instruction set Xia of independent core, core micro-structure directly from mess sequence four launches jump, it while is domestic first paragraph ARMv8 of all nuclear chip (is may is world first paragraph, but how many core number to counts as all nuclear is can discussion of at), nuclear between interconnected schema using has academia research has long but less see actual deployment of tablets Shang network (NoC) structure, in SPEC 2006 Shang of throughput test has approximation Intel of latest design.
Then take enough side, from the flow of news is that Mars has not been heard in the industry, this means that the test SPEC is not done at a real chip, are vulnerable to challenge. In addition Mars as a many-core chips have not achieved a sufficiently high degree of coupling, more like 8-chip mosaic products of Xiaomi single core performance gaps remain large (intelligent next-generation core is developing). Overall is a mixed blessing, but afterward, soar has enough pride for the achievements of the internal and external credit take time.
It is worth mentioning that, know people who are claiming to be from Hotchips site posted on the community, said Federal Presentation hit the ice, because the speaker did not estimate good Hotchips audience level, spoke at the untimely circumstances many of the basic concepts of architecture, such as sequencing buffer (ROB) the basic principle and so on, cause many professionals to disgusted. This reflects the problem is federal is not yet clear how to distinguish themselves in the international arena, is not serious in nature, as long as the individual believe after experience in several statements fly Presentation will do better, just as the core ARMv8 debut on the international stage, harvesting the reaction was pity.
Why not?
Lei Feng online an article on federal "Mars" positive coverage of the CPU: the domestic most ARM architecture, really can beat Intel's top chip? Wake, thrown in some online community was strongly negative reviews, the focus was on that "Mars" suspicions of some funds. Although the author does not recognize this extreme skepticism, but also to understand the causes behind this suspicion.
Raised such a strong rebound, its underlying causes should be blamed on the 2003 "Chinese core" scandal. The scandal broke out, completely an overdraft credit support IC projects by the Government, have had a far-reaching impact, described how I'm afraid too much. Job title of the person identity fraud was head of the prestigious Shanghai Jiaotong University School of microelectronics, fraud tools are poor migrant workers Polish, afterwards by Shanghai Municipal Government, the Ministry of science and technology, 863 project groups of acceptance, if acceptance of the Executive branch of government participation. After all, silos, not blinded by professional administrative leadership of the innocent is defensible. 863 project groups include circle a legendary old leader was cheated and so huge amounts of funds, so public reaction is particularly strong on this issue.
Han core event past more than 10 years Hou, its negative effect force still far not elimination, that Yu in online many about domestic CPU reported of comments district in the are can saw Han core was repeatedly mentioned, sometimes also and CAs calculation by name similar of Godson phase confusion, even in has nothing to do IC industry of suspected fraud case in the, are not difficult see Han core in comments and News reported in the out mirror.
Feiteng Mars suffered "cheat funding" attacks and questions, in fact, largely because the public for more than 10 years ago, "Chinese core" scandal anger disappeared, for IC projects support the trust has not been re-established, as today's dairy companies also often because many years ago "melamine" event at an absolute disadvantage in public opinion. Not difficult to meet, in the foreseeable future, and fly, Godson, Siu core, core similar to the Sheng macros in Government-backed companies and projects will be subject to the same harsh treatment in the public opinion, which require China's IC industry the majority of my colleagues work together for several years, make a real market test results to get reversed.

Conclusion
China's IC industry starts late, weak, over a number of years is difficult to Intel's supremacy in high, medium and low product lines and all-out confrontational posture, this is public, community professionals and the media should keep a cool place. Media appear less punch onto Intel, kick AMD's exaggerated, not too much CPU, China raised public awareness of the standards expected, to reverse the current of public opinion is so good. From another side for, China CPU currently made of results also should be encourages and support, in more nuclear/all nuclear of Huff performance Shang, has has more than soar a company progress to has and Intel design similar or flush of standard, and using of process also reached has even in global range view is quite tip of standard, from this angle Shang said, we also without too inferiority. Wait time, CPU, China may be possible initially blew the kick-ass.
