Since 2010, Arm DesignStart has provided users with quick access to Arm IP. Three years ago, Arm announced the opening of the Cortex-M0 system through the DesignStart project, which also opened the wave of the development of a new wave of ultra-high-efficiency customized SoCs; last year, the Arm DesignStart project was expanded to include the Arm Cortex-M3 processor. Developers who want to design custom SoCs are paving the way to success, helping innovators bring products to market with minimal risk and turning ideas into reality.
Because of DesignStart, hundreds of embedded design developers, startups, and OEMs have become new members of the Arm ecosystem. The custom SoC design they developed brings embedded intelligence to many different IoT and connected devices. Arm has always valued feedback from all parties and has always focused on providing better products and services.
Customer success
The Internet of Things is currently attracting more and more people's attention. Mr. Sun Jinyi of Softbank once predicted that the Internet of Things is about to enter the Cambrian-style eruption. By 2035, the number of IoT devices in the world may reach trillions. The number of scales, the outbreak of the Internet of Things singularity in the near future.
The key to the realization of the Internet of Things is naturally networking, in which the IoT communication protocol is further divided into many types, including the traditional WiFi, Zigbee, Bluetooth, Ethernet, and the emerging NB-IoT. At present, our domestic communications protocol is the NB-IoT technology, and the three major domestic operators have regarded NB-IoT as the mainstream transport protocol of the Internet of Things.
Under the Internet of Things application scenario, such as a water meter, a manhole cover, and a trash can, the amount of data transmitted is very small, and the transmission distance is very long. At this time, WiFi, Zigbee, and Bluetooth often fail, and in many scenarios, the deployment of Ethernet will be very difficult and will be eliminated. The rest will only consider the 2G, 3G, and 4G network protocols used by mobile phones, but the cost and merits Consumption has restricted them.
Under this background, NB-IoT technology with long transmission distance, low power consumption, low cost and wide area coverage stands out. It is also for this reason that in the Internet of Things application, traditional mobile phone chips cannot be used, and a specialized chip for the Internet of Things is required.
In the past, the domestic Internet of Things chips were often provided by large manufacturers with large volumes. With the explosion of the Internet of Things, more innovative and capable emerging companies are required to join. In response to this trend, there was a Shanghai-based startup chip company, Core Mobile Communication Technology, that stood up to respond to the call of the country and developed a domestically ultra-low-power NB-IoT Internet of Things chip EC616. Take a look at the characteristics of this chip:
We can see that the EC616's level of technology, power consumption, and cost are very much in line with the application requirements of the Internet of Things, significantly surpassing the industry's leading level. In addition, this core product has been successfully tape-out, and it is planned to begin mass production by the end of 2018. This is really gratifying. Even more amazing is that this company was founded in 2017 and the number of companies has only reached 50 recently. How did they achieve this leap in just over a year?
☞ In fact, there are two secrets to their success:
1) Outstanding team.
The core mobile communications employees are highly educated personnel with more than 10 years of working experience. The doctoral rate exceeds 20%. The core team is from mobile phone chip R&D teams of well-known companies such as Marvell, Spreadtrum and Hass. The founder of the technology is Mr. Liu Shi. The original Marvell mobile chip team's algorithm protocol stack and senior director of system architecture, technology founder Xia Bin is Marvell worked for 14 years as the original SoC team technical director, two generals picked up the flag of moving core communications products.
They have large-scale commercial mass production of communication IC design experience and practical experience. Mr. Xiong Haifeng, the founder of the market, has been engaged in the Internet of Things chip industry for many years, and is familiar with the product definition, marketing, ecological construction and commercial operation of the Internet of Things.
2) Free support from Arm Cortex-M3 IP.
Core Technology is the first partner of the Arm Design Start project in China. Their experienced team has a unique vision. They joined the Arm Design Start project and obtained the Arm Cortex-M3 IP free of charge. It also means that the entire industry has been acquired. The support of the upstream and downstream Ecosystems, from design to tapeout, has greatly reduced working time and saved a lot of money. As a start-up company, these two are the tricks for them to throw away other entrepreneurs of the same type. The core-moving NB-IoT chip is based on the single-core design of the M3 core and removes the DSP core in the traditional architecture. It is the only company in the world to implement the NB-IoT SoC chip design through a single core so far.
The success of the core-moving communication technology has provided us with a very good example. In the future, there will be more startups in China who would like to customize a suitable chip for themselves. Then joining the Arm Design Start project will be very attractive. In addition to the Cortex-M3 Cortex-M0 is also in the project.
Color filters are flat glass or gelatin sheets of various colors. Their transmission bandwidth is hundreds of Angstroms. They are mostly used in broadband photometry or installed in stellar spectrograph to isolate overlapping spectral levels.
Its main feature is that the size can be made quite large.
The color filter is mainly used for stage lamp decoration. It has a wide variety of colors, such as red, yellow, green and blue. One of its remarkable characteristics is the absorption of light, especially the selective absorption of light with specific wavelength.
