With the further advancement of globalization of science and technology and the frequent occurrence of violent and terrorist attacks worldwide, the global security market has ushered in another spring in recent years. After more than 30 years of development, the Chinese security industry has also rapidly emerged as an important force in the world security industry. The products produced by local security companies in China not only meet the needs of the expanding domestic security market, but also are exported to countries along the Belt and Road, Europe and the United States, the Middle East, Southeast Asia, Africa and more than 100 countries and regions.
In the security industry, the core chip (master SoC, imaging sensor) technology as the main functional unit for monitoring, storage, and network transmission equipment is particularly important, but due to high technical barriers and dependence on foreign products, it is inadvertently Ignored.
After the U.S. "Prism Gate" incident broke out, this month, Intel, the world's largest SoC/CPU supplier, was again exposed to the security vulnerabilities of the CPU chip. Intel Corporation publicly acknowledges that all mid-to-high-end CPUs sold in recent years have security flaws. In order to solve the problem of system flaws, Intel has implanted AMT (active management technology) in these chips. However, this technology is not designed rigorously and can be exploited by hackers. It can be used to remotely load unauthorized programs through the network. , resulting in system crashes, simulated system security checks and other acts, and then to achieve the purpose of stealing information and hijacking system control.
From this we can see that the security of the core chip needs to be strictly controlled in the design process. The core chip design technology should not only be in the hands of developed countries, which is closely related to the progress of industry technology and the development of national strategies.
At present, China's chip technology is a technical field in which the country strongly supports development and has a promising market. In terms of markets, China is the world's largest semiconductor consumer. It is predicted that by 2025, China will occupy 50% of the global chip demand, but at present, more than 90% of chip consumption still depends on imports. Before 2014, the Chinese government had tried several times to make the local semiconductor industry bigger and stronger, but with little success. Development is the hard truth. Today, with the strength of technological decision-making, the domestic semiconductor industry is a strong support for the country's strategic direction. According to the national development program, by 2020, the annual growth rate of China's semiconductor industry will not be lower than 20%. The government will invest US$170 billion in this area in five to ten years. It can be seen that the Chinese semiconductor industry has truly ushered in. spring.
China's local technology companies are vigorously developing chip technology. Spreadtrum Communications released the 64-bit eight-core 4G chip SC9860 at MWC last year, which has achieved a breakthrough in the mid-to-high-end smartphone market. Huawei Unicorn played the role of "dark horse" in the 3G chip war. In addition to industry-specific chips for supporting network and video applications, Huawei has continued to develop and improve high-performance mobile phone chips since 2009.
In addition, looking at the security market, the supply of domestic high-performance imaging sensor chips is still in a blank state. Image sensors and other core technologies have been dominated by foreign companies such as SONY, and Chinese companies do not have an advantage in core technologies. Faced with the huge technical gap of high-performance imaging sensor chips, many domestic companies began to acquire foreign technology companies and tried to quickly fill gaps in technology and market in this way. However, the actual results prove that such a model has not been a great success, and the acquisition method is ultimately a temporary solution.
As we all know, as early as the mainstream of the market is the era of CCD image sensors, SONY dominates the image sensor market with superior technology. For many years of industry accumulation and understanding of the image field, SONY has accumulated sufficient experience in image sensor design technology. Before the large-area application of CMOS image sensors, SONY's CCD image sensors were widely used in the fields of monitoring, traffic, etc. due to their advantages in sensitivity and signal-to-noise ratio. However, CCD image sensors also have the disadvantages of slow response, high cost, and complex application design.
With the imaging market's change in demand for large resolution, high frame rate, low-cost image sensors and technological advancement, CMOS image sensors have become the current image sensor by virtue of their own advantages (high integration, excellent performance, user-friendliness, etc.) The mainstream of the market. In this new era of image sensor technology, SONY relies on strong technical strength to once again lead the CMOS image sensor market. In the subdivided areas (such as security monitoring), it also accounts for more than 80% of the global market share.
Domestic CMOS image sensors that want to chase or even surpass SONY must seek breakthroughs in technology and continue to innovate in sensor chip design technology. At the same time, it is necessary to fully understand the industry and market development trends, and even need to closely integrate with the user's true product design intent to achieve rapid response and effective response.
Machine vision/artificial intelligence The demand for imaging sensors is very different from the traditional imaging field. This emerging industry needs machines, programs, and algorithms to understand what is happening in the image. Therefore, the artificial intelligence (AI) industry has higher requirements on the performance of image sensors; in order to allow the machine to understand “semantics†in the image more quickly and accurately, the sensor needs to restore the captured image more realistically, such as a high signal-to-noise ratio. , Low illumination response, high dynamic range and no distortion of the captured image, residual image and other requirements. GlobalShutter image sensors have thus become "just needed" for the artificial intelligence (AI) industry.
In the first two industrial revolutions, China had allowed Europe and the United States to seize opportunities in technology and industry. The third scientific and technological revolution was another extremely favorable opportunity. Mastering the most cutting-edge technologies is the only opportunity and direction for Chinese companies to surpass European and American companies, and it is also the basis for Chinese companies to base themselves on the world market.
