With the rapid development of China's automobile industry and the increasing popularity of private cars, car navigation systems have penetrated into automotive electronics in large areas. From the front-mounted car navigation system that Toyota first equipped on the Vios car in 2003, the assembly rate of more than 80% of the models exhibited at the 2010 Beijing International Auto Show. Industry experts predict that by 2012, China's car navigation market will reach nearly 200 billion yuan, and its rapid momentum is amazing.

In the process of development, satellite navigation applications have quietly changed from a single GPS system era to a multi-constellation coexisting compatible GNSS (Global Navigation Satellite System) era; from a vehicle-based market structure to Personal consumption applications are the mainstream market structure; from the distribution of products to the main application of services. In this sense, the technology of the in-vehicle infotainment system at this stage is no longer a problem, all the required functions can be satisfied, and how to achieve the performance price balance of the in-vehicle infotainment system, how to create a more innovative and excellent experience. It is still the issue that is most concerned by developers and consumers.
Ye Zhiping, director of the Asia Pacific marketing department of CSR's automotive business unit, said: Like other consumer products, in the automotive electronics industry, customers also want to provide them with more (functional) cheaper products. There are two main ways to achieve this goal, one is integration and the other is consolidation. Integration includes integration of chips and platforms, and platform integration saves costs and reduces time-to-market.

At the same time, in some luxury models, the cost is not so sensitive, a good experience is a higher pursuit. For example, CSR's inertial navigation, the current best Bluetooth technology (Bluetooth 3.0, 4.0) and the recently launched SiRFprima II series can meet the needs of customers. Zoran, a US imaging technology company that recently merged with CSR, will support the CSR automotive platform with its mature imaging and video technologies.
With WI-FI technology already being used in some cars, will NFC, like the recent hot short-distance transmission technology, also enter automotive electronics? Ye Zhi said that NFC is an emerging technology. But in automotive electronics, consumers have to use a lot of money to have a market. For example, when the mobile phone NFC is commonly used, it is possible to use it in a car. If the customer does not need to integrate it, it not only increases the cost but also easily interferes with various wireless connection technologies.
Since the launch of SiRFprima for a while, many people have come up with the idea: Can such a platform be placed in consumer electronics? Ye Zhiping said that SiRFprimaII is not inaccessible to the consumer electronics market, but will not blindly enter the market. The company will selectively enter certain target markets while ensuring its competitive advantage. He also talked about the inertial navigation technology in the hands of CSR to eliminate many manufacturers who came to eat. Of course, with the development of technology, like other companies, the bottleneck of CSR is also manifested in the physical bottleneck, and the integration of more functions, from 40nm to 28nm process improvement needs to be considered.
SiRFprimaII, an extraordinary navigation and entertainment information system to the mainstream automotive market
Following SiRFprima, CSR launched the SiRFprimaII in-vehicle infotainment platform, which integrates a multi-GNSS positioning engine TriG RF supporting GPS, Galileo, Glonass and Compass satellites to improve the performance of the navigation system in the line-of-sight shielding environment, and combined with SiRFDRive positioning calculation software. Allows users to maintain unobstructed navigation regardless of driving through urban canyons, tunnels or three-dimensional parking lots.
With the ARM Cortex-A9 application processor running at up to 1 GHz and delivering up to twice the throughput of the first generation SiRFprima devices, it provides the power for the latest navigation, entertainment, communications and information applications. The image and multimedia acceleration capabilities of the SiRFprimaII SoC are three to four times that of the first generation. Using 40nm CMOS processing technology, SiRFprimaII SoC will decode a powerful application processor, multimode GNSS baseband position processor, DDR3 and NAND flash controllers, analog power management functions, advanced audio codecs, 1080p full HD hardware acceleration Technology, 3D graphics hardware acceleration, USB PHY/UART/GPIO interface and more are grouped together in a single package.
