Qualcomm has been committed to the development of wireless communication technology for about 35 years since its establishment. Ma Jinwu said, “After Qualcomm completed the standard design of R15 and R16, the network has gradually become more and more mature, and the coverage is getting better and better, we need terminals, mobile phones, various of 5G terminals are operating on the 5G network.”

According to market research, 5G will bring great improvement to the entire digital economy after it is truly commercialized. Ma Jinwu also believes that after the completion of the 5G network, many interesting applications will be developed, thereby driving the development of the entire industry and the growth of the digital economy. “Qualcomm’s focus is still on smartphones. At present, more than 100 million 5G smartphones using Qualcomm’s Snapdragon solution have been shipped worldwide, and Qualcomm also wants to expand 5G solutions to more areas beyond smartphones.

In the past two years, the application of 5G in the industrial field has been particularly hot. More and more industrial scenarios require wireless connections. Ma Jinwu introduced that, for example, some mobile scenarios in factories need to be controlled wirelessly. Another example is a smart port. Because it is very open, wiring is very difficult. Large containers need multiple cameras to shoot. The movement of the container includes the direction of movement and the angle of movement. If there is a deviation, problems will occur, so there is no way to use wired. With traditional 4G, the uplink will be limited in some scenarios, which requires a 5G network with high bandwidth and high uplink capability.

Advantest: Provide a one-stop test solution for IoT chips

At the summit forum of the Internet of Things Conference, Ge Liang, senior manager of Advantest Japan, analyzed the challenges and one-stop test solutions of the IoT chip test market. It is reported that as a leading supplier of semiconductor chip automated testing equipment, Japan’s Advantest has occupied 50% of the chip testing market in the past three years.

The IoT market has experienced rapid growth since 2016.

According to Ge Liang, senior manager of Advantest testing, there are three major challenges in IoT chip testing: 1. IoT chips are compatible with multiple wireless standards, including WiFi, Bluetooth, and NB-IoT. Each standard corresponds to different functional modules in the chip. It means that the test of the radio frequency of the chip is the most complicated. When there are multiple radio functions in a chip, the complexity of the whole test increases exponentially. 2. The integration of IoT chips is getting higher and higher, including wireless radio frequency capabilities, ADC/DAC, power management capabilities, etc. Appropriate test instruments must have high coverage in related fields; 3. IoT chip and module applications Wide range and relatively low price, which means that the requirements for low-cost testing are relatively high.

In response to the needs of IoT chip testing, Advantech has launched a one-stop testing solution. Ge Liang pointed out that providing a one-stop solution includes testing equipment, tested circuit boards and testing procedures. The V93000 platform is the cornerstone of Advantest’s automated testing. The family includes models such as V93000-A, V93000-C, V93000-S and V93000-L. Wave Scale RF is Advantest’s recently launched series of channel cards for the V93000 platform, which can both test low-cost Internet of Things (IoT) devices , can also test high-performance mobile communication equipment. For IoT devices, Wave Scale RF can test communication protocols such as -M, WLAN, , and other communication protocols; for mobile communication devices, it can deal with the latest communication technologies such as LTE-A, MIMO, carrier aggregation, and even communication protocols above CAT 10.

The one-stop IoT test solution launched by Advantech mainly includes three contents: one is the V93000 Wave Scale test product; the other is the IoT test daughter board. Users can use the daughter board to design small boards, reducing the cost of cost. The third is to provide test program guidelines through plug & play IoT, and finally provide suitable IoT test solutions to Chinese customers.

He focused on auxiliary solutions for smart wall solutions and charging power solutions for wall sockets and power strips. The realization of the smart switch is to replace the traditional mechanical switch with a relay, and to add sensors, a wireless connection module and an auxiliary power supply of an AC/DC power supply to the smart switch module to supply power to these modules. When the relay is disconnected, The LED light is off. However, at the same time, the sensor, wireless connection module and AC/DC power supply must continue to work to wait for the user’s remote control light-on signal. The current of this part of the circuit will return to the zero line through the LED light to realize the power supply loop.

The LinkSwitch-TN2 series launched by PI can meet the needs of intelligent switching power supply. There are three main advantages: First, the standby power consumption of the chip is low, and it can enter the frequency reduction mode when the load is light. The operating frequency of the intelligent switch is lower than 100HZ, which is very power-saving. Second, the PI has a patented technology that can average the input current. processing to reduce peak current. The third is that the chip can support a variety of topologies, including buck, boost and flyback topologies, which can achieve high precision, high efficiency and excellent no-load performance.

Applications for the LinkSwitch-TN2 series include home appliances, heating ventilation and air conditioning (HVAC), industrial controls, smart home (IOT) and electricity metering systems. According to Wang Hongkui, the LinkSwitch-TN2 IC is available in three different packages: PDIP-8C, SO-8C and SMD-8C.

Wang Hongkui pointed out that the LNK3202D is suitable for very low standby current, and the input standby current is only 48 microamps when it is completely no-load. He also introduced that PI’s latest product is the InnoSwitch3 series, which has shipped more than 1 billion InnoSwitch series ICs worldwide.

Baidu face & behavior detection software and hardware integrated solution and Kunlun AI chip

In this event, Baidu senior technical manager Wang Xuejun shared Baidu’s software-hardware integrated solution for face & behavior detection. Wang Xuejun said that software-hardware integrated AI products mainly refer to AI products on the end-side and edge-side. These products have the characteristics of better cost, closer to customer needs, and better hardware adaptation indicators.

AI software integration has some advantages, such as differentiated design, which may expand the value of the entire project. Therefore, AI software and hardware integration products are the role of value amplification and value leverage.

At the same time, Baidu also launched end, edge and cloud products, and finally formed a solution of end, edge and cloud. Wang Xuejun introduced that this scheme has several advantages, one is the most cost-effective, the second is the short deployment period, which is shortened from 6-12 months to 1-3 months, and the third is that it has strong confidentiality and security. Data encryption function.

In addition to the software and hardware integrated solution, Luo Hang, a senior R&D engineer at Baidu, also brought a computing power solution in the Internet of Things era – to apply for Kunlun AI general processor. Luo Hang said that IoT + AI chips are an inevitable choice for the digital industry in the new era, and an inevitable choice for evolution. With the increase of data and more and more devices, it is necessary to have models or algorithms for AI processing to process the data.

Luo Hang believes that data is an element, that is, means of production, and computing power is productivity. The digital industry is an AI chip. This definition can be a general AI chip, or it can be an AI chip on the cloud or end. Data and computing power are complementary and indispensable.

Figure: Luo Hang, a senior R&D engineer at Baidu

The current AI application scenario solutions are mainly concentrated in the three categories of vision, speech and natural language processing, but smell, taste and touch have not yet been achieved, which is the direction of future efforts.

The Baidu Kunlun chip was born in 2011, and the design plan was launched in 2018, and more than 20,000 chips have been deployed so far. At present, Baidu Kunlun AI chip has several characteristics. One is high performance, which is better than NVIDIA Tesla T4; the other is low cost and low power consumption, which is also 25%-45% lower than that of Tesla T4; Flexible and versatile.

At present, Baidu Kunlun chips have been adapted to mainstream domestic operating systems, such as Kirin and Tongxin, and have also been equipped with mainstream domestic CPUs, such as Kunpeng, Feiteng, Haiguang, and Shenwei.

In 2021, the rapid development of the Internet of Things will coexist with price increases and shortages

According to a report released by the GSMA, the total number of global IoT connections reached 12 billion in 2019, and it is expected that by 2025, the total number of global IoT connections will reach 24.6 billion. Data released by Machina shows that the explosive growth of IoT applications in China will exceed 7 billion in 2020, and the number of connections will exceed 10 billion within three years.

Huang Jingjing, executive editor-in-chief of Electronic Enthusiasts Network, shared the “2020 IoT market development status and trends” and said that this year, the Internet of Things has made positive progress in the perception layer, connection layer and platform layer. In the perception layer, the demand for anti-epidemic infrared temperature measurement chips has exploded this year. The connection layer has various connection technologies such as WIFI, Bluetooth, 5G, NB-IOT, cat.1, etc., and has developed to a new stage this year, such as the number of 5G base stations. Reaching 700,000, NB-IOT will exceed 100 million this year, and CAT.1 will attack the medium-speed market of the Internet of Things. At the same time, a large number of module manufacturers have launched new module products, strengthening the connection between new technologies and applications.

After 30 years of scientific research and development, from Beidou-1 to Beidou-3, the last Beidou satellite was launched this year, and China’s Beidou navigation system has made significant progress. The localization rate of the core components of the Beidou-3 satellite navigation system has reached 100%.

The RISC-V ecosystem has grown and grown, and the performance of processors based on the RISC-V architecture has been continuously improved. With the increasing number of IoT devices, IoT security has become the focus of manufacturers. This year, the original factory in terms of security chips and technologies There are also many actions. There is also the Internet of Things operating system. All major Internet giants have launched their own operating systems.

The non-contact economy related to the epidemic and the demand for long-distance networks have promoted the growth of related applications. Huang Jingjing said that according to the continuous tracking report and analysis of the Internet of Things industry this year, Electronic Enthusiasts Network summarized the ten growth points of the Internet of Things. Shared equipment such as charging piles, shared scales, and the earliest shared charging treasures; intelligent medical care, the networking of medical equipment, and telemedicine, 5G telesurgery will also be truly applied in the future, and so on.

The overall first half of this year was weak, and demand was concentrated in the second half of the year, which also caused significant fluctuations in the supply chain. When the epidemic broke out around the world in the first half of this year, many countries and regions announced the closure of cities, affecting the production and transportation of local semiconductor factories, resulting in a shortage of supply of some components. On the other hand, under the U.S. ban on Chinese semiconductors, the industrial landscape has changed dramatically.

So in these contexts, the price of semiconductor devices has risen across the board. From wafer foundry to packaging and testing, MOSFETs, power ICs, MCUs, crystal oscillators, storage, etc., the information obtained by Electronic Enthusiasts Network from the supply chain can be seen that there are different levels of price increases in each link. Huang Jingjing analyzed that the reasons for the price increase are: first, the retaliatory rebound in demand in the second half of the year; second, Huawei’s early orders squeezed production capacity, and the order backlog of other manufacturers was released; , customers increase stocking, increase order volume, order is enlarged and so on. It is expected that the price increase of components in the first half of next year will continue.

The development of the Internet of Things is supported by advanced technologies and industrial policies. Of course, the supply chain also affects its development. The Internet of Things itself is also facing breakthroughs in many aspects such as sensor technology and security technology. Looking forward to 2021, the pulling effect of 5G and new energy vehicles will continue. Giants will lead the construction of data centers and AI. The opportunities for domestic chips in consumer and industrial sectors will expand, and the development of AIOT will enter a new stage.

SoC IP Enables Smart IoT

Imagination is committed to the construction and adoption of AI, automotive, wearable and smart cities, promoting the development of smart IoT and the market, and building smart cities. Huang Yin introduced that there are already many AI application scenarios in smart cities, such as security detection, smart factories, and smart non-sensing temperature sensing.

For these application scenarios, special chips will be designed, but these chips usually lack performance in some applications. For example, the CPU has high flexibility but lacks efficiency, while DSP has high flexibility but its optimization is not good enough. . The GPU + neural network accelerator can maintain both flexibility and compile, which is a good combination for AI chips.

From the data point of view, if the computing power of ordinary mobile CPUs is 1 times, the computing power of the Power VR series neural network accelerators provided by Imagination can reach up to 199 times. At the same time, this set of neural network accelerators has strong compatibility, which can be compatible with common frameworks upwards and different hardware configurations downwards.

Huang Yin said that Imagination has participated in many AIoT co-constructions, and has cooperated with Baidu, TensorFlow, and different RISC-V manufacturers. From the perspective of the development of AI chips from 2017 to 2024, the future will be the computing training chips and the edge computing chips on the end side.

At present, Imagination’s neural network accelerator IP has been applied and promoted in some enterprises. For example, UNISOC’s chip platform T710 adopts Imagination’s solution, which can perform some tasks such as facial recognition, gesture recognition, and judgment of the current state of the driver. application.
