Shencong TH2608 : Low-power artificial intelligence human-computer voice interaction chip
After buttons and touch screens, many people regard voice control as the next key technology for human-computer interaction. Because of the huge market capacity, many manufacturers have joined the field, including Shanghai Shencong Semiconductor, which was jointly established by voice algorithm giant AISpeech and well-known institutions such as SMIC.
Wu Gengyuan, Co-founder and CEO of Shencong
Wu Gengyuan, co-founder and CEO of Shencong, said that Shencong Intelligence relies on the intelligent voice technology and resource empowerment of the AIS Group and focuses on creating an integrated "algorithm + chip" solution. The company's first-generation chip TH1520 has completed mass production and shipment, and has been implemented in three major scenarios in the fields of smart home white appliances, black appliances and smart cars. The company also has three core customers: Midea Group, Hisense Group and DDPAI (whose end users are the No. 1 smart terminal brand in China).
At this year's Songshan Lake conference, they brought a new generation of chips - Shencong TH2608. According to reports, Shencong Intelligent's second-generation chip TH2608 has undergone a greater upgrade based on the first-generation chip TH1520:

Beijing Zhicun WTM2101 : Ultra-low power storage and computing integrated chip for wearable devices
Li Xiang, vice president of Beijing Zhicun, said at the Songshan Lake Forum that with the development of technology, the "storage wall" problem faced by traditional AI chips is becoming more and more serious, which is mainly caused by the inherent deficiencies of the von Neumann architecture.
Li Xiang, Vice President of Beijing Zhicun
Data shows that over the past years, computer architecture has been developing in accordance with the von Neumann architecture. In this architecture, the most obvious feature is that its computing and storage are discrete and evolve independently. In the past, the development speed of processors has always been ahead of memory, which has infinitely magnified the accumulated memory shortcomings. According to Li Xiang at the meeting, the storage wall problem is mainly reflected in the two aspects of slow data transfer and high power consumption.
To this end, Zhicun promotes the development of storage and computing integrated chips, striving to help customers solve this problem.
From Li Xiang's introduction, we learned that Beijing Zhicun Technology Co., Ltd. is an internationally leading integrated storage and computing chip company, established on October 23, 2017. The company team has 80 people and has been developing integrated storage and computing chips for 6 years. The founding team completed the world's first analog integrated storage and computing deep learning chip in 2016.
He further pointed out that Zhicun's storage-computing integrated technology innovation uses Flash memory to complete the storage and operation of neural networks, solving the AI storage wall problem, improving computing efficiency and reducing costs. Currently, Zhicun has launched the world's first storage-computing integrated accelerator WTM1001 and the first storage-computing integrated SoC chip WTM2101.
As shown in the figure below, this chip has achieved good performance in terms of package size, computing power, power consumption and efficiency, which enables it to provide strong support for applications such as wearable devices and smart terminal devices that have rigid requirements for low power consumption.
CorePu XP5127 : 5G n77 1T2R RF front-end power amplifier chip
The arrival of 5G not only makes Qualcomm, MediaTek and other mobile phone chip manufacturers earn a lot of money. At the same time, related RF suppliers can benefit a lot from it. This is mainly because 5G brings more frequency bands, higher bandwidth, and also needs to be compatible with the previous 4G, 3G and 2G. For this reason, this brings opportunities to the corresponding RF suppliers. Domestic RF industry practitioners have also seen this opportunity and are waiting for the opportunity to rush in. Xinpu Technology is one of the representatives.
Gu Jianzhong, Founder and COO of Xinpu Technology
Gu Jianzhong, COO of Xinpu Technology, said at the meeting that the arrival of 5G not only brings more frequency bands (such as n77), but also requires simultaneous connection to previous networks, which puts higher requirements on the corresponding radio frequency. As a team with rich experience in the radio frequency industry, Xinpu Technology's 5G n77 radio frequency solution has also been continuously upgraded from the first generation to the second generation.
In the first-generation 5G n77 solution, Xinpu Technology equipped it with 2G TxM, 3/4G MMMB PA, 5G MMMB PA, 5G n77 PA and 5G LFEM, supplying and demanding 7 RF modules to realize all RF functions of the main 2/3/4/5G.
Based on the first generation, Xinpu Technology launched the second generation solution XP5127. According to the introduction, the company has realized the most streamlined design, reduced product materials, integrated one transmission and two reception channels, and at the same time, the two n77 receiving channels achieve high isolation to ensure MIMO receiving performance.
Gu Jianzhong said that compared with the first-generation 5G n77 solution, the second-generation 5G n77 solution can achieve the functions required by the original 7 modules with only 4 RF modules, which can greatly reduce the RF materials and design space. He further pointed out that the 5G RF front-end power amplifier chip that debuted at this summit supports HPUE PC2 in all frequency bands and integrates GaAs PA, RF SOI LNA Switch and filter chips with various processes in a volume of 3mm*5mm, providing a fully differential RF solution.
"Compared with single-ended solutions, the heat dissipation performance is better and the performance has been greatly improved. Under various 5G modulation waveforms MPR0/1/3/6.5, the linearity and current indicators are ahead of the first-tier European and American manufacturers." Gu Jianzhong emphasized.
Huajing ML-2670-3525-DB1 : High signal-to-noise ratio MEMS microphone
Founded in 2010, Huajing Sensing Technology Co., Ltd. is another important participant in this year's Songshan Lake Summit. The high signal-to-noise ratio MEMS microphone ML-2670-3525-DB1 is their leading product.
Miao Jianmin, Chairman of Huajing
According to the company's chairman Miao Jianmin, for accurate speech recognition and efficient active noise reduction systems, high signal-to-noise ratio MEMS microphones can provide high-quality sound signal input for the entire system. They can not only provide higher-quality sound signals for noise cancellation algorithms, but also greatly reduce environmental and background noise, making it easier for the system to find recognizable content features. When picking up sound at a long distance, using a microphone with a high signal-to-noise ratio can double the capture distance without reducing signal quality. This is exactly the advantage of their ML-2670-3525-DB1.
The reason why it can create such a competitive product is mainly due to the company's possession of core silicon microphone chip technologies such as backplane and diaphragm.
First, let's look at the back plate. Miao Jianmin said at the meeting that many silicon microphones currently use acoustic holes of the same size on the back plate, which will reduce their ability to resist blowing and falling, and it is difficult to pass the 0.8MPa strong blowing test. At the same time, uniform hole diameter and hole spacing are not conducive to reducing acoustic noise and it is difficult to improve the signal-to-noise ratio of the microphone.
"The acoustic holes in the back plate of the Huajing Silicon microphone have a large aperture and a small hole pitch in the middle, and a small aperture and a large hole pitch at the edge. The principle is that the maximum stress on the back plate is at the edge when it is under pressure. The small aperture and large hole pitch at the edge are conducive to bearing the high stress of the back plate at the edge, thereby improving the pressure resistance; at the same time, although the pressure in the center is small, the vibration amplitude of the diaphragm is large, so the acoustic pressure is large. The large aperture and small hole pitch in the middle are conducive to the timely release of air molecules to reduce acoustic noise and improve the signal-to-noise ratio of the microphone." Miao Jianmin continued.
Let's look at the diaphragm. From Miao Jianmin's introduction, we know that the diaphragm of many silicon microphones is generally a simple flat plate. This results in the diaphragm being unable to be released during the manufacturing process, greatly affecting the consistency and yield of silicon microphones. This also makes their resistance to blowing and falling poor, and it is generally difficult to pass the 0.8MPa strong blowing test.
However, Huajing's silicon microphone diaphragm design adopts corrugated and fan-blade microstructures. The corrugated microstructure on the edge of the diaphragm can reduce the stress of the diaphragm process, thereby improving sensitivity, consistency and yield. The same eight fan blades automatically open to release airflow, thereby avoiding damage and breakage of the diaphragm.
In addition to good design, Huajing has also established an advanced sensor production line. The company also has hundreds of square meters of Class 100 and Class 1000 clean rooms, which are used for MEMS sensor chip testing and sensor finished product testing respectively. The above hardware level helps them create a leading solution.
"Our silicon microphone products have excellent performance and have been supplied to several well-known domestic companies," said Miao Jianmin.
From the company's information, we learned that in addition to the silicon microphone series (Huajing Technology brand), the company also provides a pressure sensor series (Huajing Sensing brand). The pressure sensor series products include chips and modules, as well as various automotive pressure sensor components, among which automotive sensor component products have entered well-known domestic electric vehicle brands.
In addition, the company will also invest in the research and development of 5G SBAW.

He further pointed out that this series of products has an integrated 32-level first-in-first-out (FIFO) buffer that allows users to store data to limit the intervention of the host processor. The two independent and flexible interrupts it provides greatly simplify the algorithms used for various motion state detection. Standard I2C and SPI interfaces are used to communicate with the chip.
“依赖于这样的设计，明皜传感科技能够为VAD语音唤醒辅助功能，精准发声定位，通话降噪辅助和骨声纹识别辅助等应用提供支持”，汪达炜说。
In the process of introducing this series of new products, Wang Dawei also talked about his insights on MEMS sensor products. He pointed out that the MEMS industry must say goodbye to "hard work" and "low prices" and realize its own dreams. To achieve this, the key lies in the ability of technological innovation and industrial chain integration, the execution of large-scale production and the change of business model, not just relying on selling "chips".
