Risc-v’s success means that Softbank’s arm has been seriously affected. Arm is trying to expand its dominance in the smartphone sector to other markets. Arm has recently lifted a stone and hit its own foot. For some reason, arm recently launched a website to attack its competitor, risc-v, an open-source chip architecture.

Arm, the world’s leading embedded enterprise, is suffering a lot. This kind of suffering comes from its parent, RISC. Just like the pronunciation of RISC, arm is about to risk. Recently, huami technology released Huangshan No.1 chip, which is known as the first artificial intelligence chip in the field of intelligent wearable. It uses risc-v architecture instead of traditional arm architecture, so it is also the world’s first risc-v open-source instruction wearable processor. Risc-v’s success means that Softbank’s arm has been seriously affected.

Nowadays, wearable devices are becoming more and more homogeneous. The same shape, the same processor, the same function, it seems that every wearable device is the same, there is no place for innovation. As the world’s second largest wearable brand, it is necessary for huami to build hardware barriers at this time point, so as to create differentiated competition. Huami technology has developed huangshan-1 artificial intelligence chip based on risc-v instruction set. For huami, huangshan-1 has milestone significance in its chip development.

Huangshan 1 can be said to be a chip with golden key origin. At the beginning of its appearance, it has three first titles. It is the first risc-v processor in wearable field, the first processor integrating neural network acceleration module in wearable field, and the first processor integrating always on module in wearable field. Compared with arm cortex-m4 processor, the operation efficiency is 38% higher. The processor has four core AI engines: heart biometric recognition engine, ECG, ECG pro, arrhythmia monitoring engine. Huangshan No.1 has the highest main frequency of 240mhz and 55nm process technology. It has three characteristics: AI drive, lightning performance and slim power consumption. At present, the chip has been successfully taped and will be officially applied in the first half of 2019.

The release of Huangshan No.1 AI chip not only gives us a vision of more possibilities for wearable devices in the future, but also greatly promotes the development of the whole industry. Even the chairman and members of risc-v Alliance said: Huangshan No.1 artificial intelligence chip is the first wearable processor based on risc-v in the world, and risc-v application scenario expansion has made a great step forward, expecting its brilliant performance in the field of intelligent wearable.

It’s no surprise that this massive processor was released by huami. In recent years, with the explosive growth of wearable market at home and abroad, huami can be said to be the biggest beneficiary. The current market share of Xiaomi Bracelet exclusively provided by huami to Xiaomi is the second in the world, second only to apple, and the third is Fitbit. From this point of view, it is reasonable that Huangshan No. 1 was produced by huami.

Huami technology also mentioned that they invested in sifive in June this year. The latter is a company specializing in risc-v processor IP, which was founded by risc-v inventor in July 2015. It is the first semiconductor enterprise based on risc-v system in the world. It has branches in 10 countries and regions, and has become the largest risc-v commercial company at present.

As the name suggests, risc-v is the fifth version of RISC. RISC, or “reduced instruction set computer”, is just the following two new Turing Award winners, John L. Hennessy and David A. Patterson, who have made great contributions to the industry. It was released by the University of California, Berkeley, in 1980. Chip instruction set is the basic component of computer, which helps computer software communicate with underlying hardware devices.

ARM chip design is based on the early RISC architecture. Arm has licensed the design to a number of chip vendors, which are used in almost all smartphones. Risc-v is not only competing with arm, but also an alternative to x86, which may eventually pose a threat to Intel and AMD. However, in the PC and server market, the existing chip architecture is very strong, so risc-v can not set off too much waves in the short term.

Like Linux, which dominates the server operating system, risc-v is also an open source technology, which does not belong to a specific company. If it continues to develop rapidly, it may become the first widely used open source instruction set design. Many risc-v researchers compare the energy of this circle to the Linux open source movement of the 1990s. At that time, many people in the technology industry were skeptical about the success of open source operating systems. However, in the end, Linux has become the dominant operating system in the server field, and has become the foundation of Android system.

Risc-v also has the function of fragmentation. The so-called fragmentation refers to supporting chip design companies to add additional functions on top of the core architecture, which enables enterprises to customize chips according to their own needs. As a result, like Android, millet looks like millet, and Huawei looks like Huawei. In contrast, the arm instruction set does not support such a modification.

Risc-v’s success means that Softbank’s arm has been seriously affected. Arm is trying to expand its dominance in the smartphone sector to other markets. Arm has recently lifted a stone and hit its own foot. For some reason, arm recently launched a website to attack its competitor, risc-v, an open-source chip architecture.

This move, by oneself employee denounces as “the method is despicable”. The site survived for a day and ended up empty and closed. This short-lived website is rscv- basics.com It went online quietly on July 9. The target is clear. It is risc-v open source processor architecture. The content is not complicated. For those who want to make chips, it introduces “five things to consider before designing SOC”, including cost, ecosystem, fragmentation, security and design assurance. Everything includes a reason why arm’s cortex is better than risc-v. In addition, when Google searched risc-v, it was this website that ranked first.

This shows that arm has put the keywords of competitors for this website, which is simple, fast and highly targeted. The spirit of gossip among netizens is burning, and this website has quickly become a hot topic in various science and technology forums. The engineers in the industry are furious, and the employees of arm also include them. They mercilessly criticize that it is really mean to build such a website.

As soon as the website spread, arm had internal and external troubles. On July 10, the website was closed and emptied, and the page became a blank. Subsequently, an arm spokesman complained against the register, a British technology media. He said that arm “provides these key considerations about risc-v commercial products” and does not want to stigmatize its competitors. It originally wanted to stir up some discussion about architecture in the industry. Based on the early RISC architecture, ARM chip design is derived. Arm has licensed this design to a number of chip manufacturers, and now almost all smart phones are inseparable from it.

“Arm is too expensive.” Said jothy Rosenberg, co-founder of Dover Microsystems, an information security chip company. According to the information report, arm’s high price has pushed more than 80 technology companies, including Google, Qualcomm and Samsung, on the same front. They are working together to develop new open-source chips to provide a lower cost chip for mobile phones, tablet computers and autonomous driving, which are in great demand.
