Since we are in May 2001 began to develop the LongXin processors, LongXin has been six years of history. Since then, LongXin is in the interest and concerns of opponents and questioned the advances. We have every step of the old problems will disappear, while new issues will be more difficult to come out. To sum up, the LongXin growing up, one after another must answer three questions, or to fight the battle of the three. The first issue is "China should develop generic CPU"; The second problem is that "China has the capability to develop generic CPU"; The third problem is that, "LongXin can not be sold." In the past six years, we have successfully answered the first two issues, and achieved the victory of the campaign before the two are now facing is the third question, or the third battle, LongXin on the road ahead is the most crucial one Battle of the market.

In the beginning LongXin development, we have to answer the first question is "whether or not the development of China General CPU", the issue seems simple now, in fact, was not the answer. For various reasons, in China¡¯s "Eighth Five-Year Plan" and the "Ninth Five-Year Plan" period not to deploy the development of generic processor; in the "Tenth Five-Year Plan" in the early, more mainstream view is that our country should be dedicated to the development of embedded processor-based Not to develop high-performance general processor. Li GuoJie, director since 1999, we called the "Five-Year Plan" period should make great efforts to make generic processor that missed the last five years in the future there will be no chance. In 2001, and in the absence of any application for funding out of the calculation of the financial innovations of all time (10,000,000) processors to develop common projects. Very ashamed, I just think that at the beginning of the publicity around in the development of generic processor is a more than speculation, and later as a result of a chance to start doing has been done today.

Therefore, on August 10, 2002 LongXin-1, marked the successful development, "not to develop generic CPU" We have answered this question, we have won this battle. After the "Tenth Five-Year Plan" period, we have plans to get 863 countries and the Chinese Academy of Sciences Knowledge Innovation Program funding support.

We have to answer the second question, or fight the battle in the second "China has the capability to develop generic CPU". It was a tough battle because of all high-performance processor chip, the core of the chip, but also the most difficult to design the chip. In 2002, we successfully developed LongXin-1 GHz processor 266MHz, a lot of people that met on the Pentium II processor performance, at the beginning of our own understanding of it is not clear. However, with the internationally recognized standard testing procedures SPEC CPU2000 tests, the LongXin-1, found that the actual performance is the same frequency of the Pentium II processor, about half of the successful development of LongXin-1, the joy of performance was not depressed by the Replace (In fact, the Pentium II processor has been used to launch three of the ILP structure than the natural structure of the launch of the single-LongXin-1 high-performance. LongXin-1 through the current structure has been optimizing performance enhancement ). Yong having a sense of shame and then, later in the LongXin-2 processor family development, we used to launch a four-out-of-order execution structure, in 2003 the successful development of LongXin 2B performance of LongXin-1 is 3 times more than the same The frequency of the Pentium II processor
Energy; in 2004 the successful development of LongXin-2C by enhancing the frequency and optimize the structure of the performance of LongXin 2B is three times as much to the performance of the Pentium III processor, but the performance did not meet the same frequency Pentium III processor 2 The goal of times; in 2005 the successful development of LongXin-2E In addition to using 90nm process to increase frequency, Memory bandwidth is still a great effort from top to bottom, its performance is 3 times that of the LongXin-2C to the Pentium Low IV processor performance. In this way, through three consecutive years, three times a year to improve the performance of the "triple jump" to LongXin-2E (On this basis, as well as for improving the mass production of LongXin-2F) in a single processor to achieve the advanced level in the world to achieve China¡¯s high-performance CPU common development by leaps and bounds. In the above-mentioned triple jump, that it is technically no longer a low starting point, the final level is the most difficult. In consideration of our own "Five-Year Plan at the end of" the last dive when they do not have such a high goal, the Ministry of Science and Technology Division of the leading high-tech analysis that we should walk across the road of innovation, and we have successfully placed Beishuiyizhan position. After our in-depth analysis and exploration, the development of a risk to a certain extent but is likely to achieve the technical line, and successfully completed the development of the LongXin-2E.

The successful development of LongXin processors in the international community has aroused strong reaction. In July 2005, the United States well-known market analyst firm In-stat in the authority of the publication "Microprocessor Report" published an article detailing the design of the LongXin-2, referred to in the article "China has to deal with a world-class design ... ...¡¯s Ability to LongXin-2, designed to show the Chinese people are preparing to produce the world as any other processor manufacturers. "Well-known Washington think-tank the Hudson Institute (Hudson Institute) submitted to the United States Congress A report entitled "China¡¯s quantum leap" in the report, an analysis of China¡¯s military technology and competitiveness. In his report, the Hudson Institute cited China¡¯s independent innovation of the three cases, one of the LongXin-2 is available. World-renowned semiconductor company STMicroelectronics to buy the LongXin 2E/2F production and marketing authorization to create the core technology of our computer¡¯s mandate precedent.

Therefore, in order to the successful development of LongXin 2E is marked, we answered, "China has the capability to develop common processor." To be sure, the LongXin-2 processor family of the study while in the process of developing our ability to set up. We had to win this battle. LongXin processors through the development, we also recognize that we must have confidence in the conduct of independent innovation of China¡¯s information industry in the core technology is entirely through innovation across a breakthrough. Independent innovation need not fear a ghost, the yield to the spirit.

Now we are faced with a third or a third battle, that is, "LongXin can not be sold." This is something we also have a process to raise awareness. In 2005, LongXin R & D and industrialization in a largely isolated state. I remember in April 2005, we held in the Great Hall of the LongXin-2, the outcome of the conference, there are a lot of phone calls to my office to ask where you can buy LongXin-2 chip, I was speechless. As a result, beginning in 2005, the group sent the backbone of LongXin participate in the industrialization of work, and clearly, "so that downstream customers find LongXin" slogan. After two years of hard work, LongXin can not be sold on this issue, we have made some progress, or to obtain a small part of the battle victory, for example, LongXin in the national security aspects of the application made significant breakthroughs, including STMicroelectronics, the mandate of the LongXin-IP has been authorized by the cost-effectiveness, as well as the LongXin processor-based systems has been completed in the test market is gradually. But away from the win the final victory there is still a long way to go, need to pay long-term and arduous efforts. The battle Our goal is to "11th Five-Year Plan" period LongXin be on the market forces can not be ignored, "Shier Wu," LongXin during the market has become an important impact on the power.
