Automotive multimedia entertainment systems can be divided into three main categories: audio (CD), video (DVD), and navigation and telematics services. Its main features are: simultaneous multi-media processing (GPS navigation and AV playback), processing and display time synchronization (map, landscape movement and camera image display, etc.), multi-screening and multi-display (driver seat and Image processing of the rear seat, etc.). Advances in semiconductor technology have made traditional simple audio and video systems (such as radios, CDs, DVDs, etc.) a thing of the past. The latest requirement for car entertainment is that car entertainment systems are expected to achieve the same results as home, as well as with consumer electronics. Connected flexibility. Therefore, a single platform that supports communication between cars and portable devices is a new issue for IC suppliers.

The latest developments have already brought USB, MP3, Bluetooth, iPod and Dolby into the car. But this is bound to provide a more complex architecture and higher performance processors. Just like other products in the consumer space (such as computers, home entertainment centers, portable entertainment devices), the car has become a convergence application that brings together audio, video and data for entertainment. Today's in-car entertainment centers must provide navigation, integrated video and assisted driving applications, as well as connect to content that provides personalized services and protect files from malicious content. In response to this requirement, Shanghai Chenhan Electronics' in-vehicle intelligent terminal makes full use of the powerful functions of a single processor to reduce the cost, size and development time of the telematics system by integrating many telematics tasks into one processing platform. The i.mx536 with digital signal processor and control processor is a powerful CPU that supports multiple standards and provides multiple formats for the car, as well as CAN bus and MOST bus connections.
Expensive and long development time has always been a bottleneck in the development of GPS systems. I.mx536 is also one of the solutions to these problems. In GPS systems, the performance of i.mx536 can replace a large number of independent processor subsystems, providing remote communication system developers with the right processing power.
Due to the need to identify and transmit data from multiple sources, the engineering of automotive multimedia systems faces unprecedented challenges. While the next-generation in-vehicle network can handle the data generated by in-vehicle entertainment systems, it is not just a broader data channel that can solve these challenges. The most complex applications involve identifying data streams such as video, audio, and 3D graphics, and then importing the correct device in the correct format. For example, in a navigation system, to obtain real-time GPS data to report traffic conditions or to rearrange driving directions, a 3D rendering engine must be used. The car camera helps the driver to observe all corners of the car from 360 degrees, enhancing the safety of the driver. In this case, the infotainment system must be able to simultaneously decode multiple video streams, including cameras, as well as entertainment information from DVDs or other data sources. The challenge for system integrators is that the system must be designed to meet the needs of different markets. This will be a daunting task as the viewing habits, delivery technologies and multimedia formats of the major automotive markets around the world are different.
To meet the market's requirements for multimedia entertainment systems, new design ideas must be adopted. Shanghai Chenhan Electronics' car smart terminal can solve these problems very well. This is an intelligent solution. The chip is not only very flexible, but also can be upgraded. The platform is derived from the i.mx536 and meets the processing power and flexibility requirements, and includes the engineering foundation required for automotive applications, such as the software and hardware architecture required for perfect tuning. The solution includes a programmable chip with a high-performance DSP engine that matches the modular software architecture, which is tuned to new codecs and communication standards and speeds up the integration of new software components.
A new generation of audio systems requires ever-increasing speed and integration of audio processors. Affected by price and power consumption, the most basic car entertainment system in the past was limited to ordinary audio and video systems, and the sound system was not very complicated. However, in recent years, due to the improvement of DSP processing performance and the reduction of system cost caused by the integration of analog circuits and peripheral components, it has become more and more advantageous compared with analog systems, and has been widely used in the automotive market.
The key to the success of Shanghai Chenhan Electronics in automotive smart terminal solutions is to provide scalable and scalable products, offering a wide range of options in terms of cost and performance. This gives automakers the flexibility to customize solutions for every business strategy while meeting stringent market and consumer requirements.
In today's new cars, a large number of automotive electronic systems such as navigation systems, rear seat entertainment systems and game consoles are used. These consumer applications require various graphics processing functions. In addition, the road departure warning system and the night vision system also require a large amount of graphics processing. At present, the breakthrough of FPGA technology can realize the high-quality graphic display function of home theater in the car.
The above-mentioned conventional multi-screen display of different content solutions mostly adopts an X86-based industrial motherboard, expands a number of graphics cards, or requires multiple PC-like products to implement the above functions. The benefits of a solution that can be ARM-based are obvious. The low-power and high-low temperature properties of ARM chips for the industrial industry, combined with its lightweight, portable features, greatly expand the range of product deployment and activities. At the same time, the cost is reduced by more than half compared to the solution using the PC architecture.
However, implementing the above dual-screen vision solution on an ARM-based processor requires a very high level of technology accumulation. It requires sufficient experience in multi-channel display interfaces, chip and system design of different display devices, and at the same time The chip layer, hardware layer, kernel layer, display frame layer, and operating system framework layer all need to have clear understanding and research. If combined with multi-channel asynchronous audio, multi-channel asynchronous video input is more complicated, far beyond the overall architecture. The range of capabilities of current mobile smart terminals. Therefore, there is currently no mature standard interface and business case for implementing dual-screen vision under Android.
Freescale's iMX53 chip is the most mature ARM processor for industrial automotive, and Shanghai Chenhan Electronics has realized asynchronous dual-screen or dual-screen vision technology. This technology has been successfully applied in the harsh environment and rich applications of automotive, outdoor advertising and other fields.
