GPS car navigator can multimedia entertainment dual difference significant

Car multimedia entertainment system can be divided into three categories: audio (CD),video (DVD), navigation and remote information service. Its main features are:simultaneous multimedia processing (GPS navigation and AV player), synchronousprocessing and display the time (mobile and camera image map, the scenery of thedisplay), multi screen and multi display (image processing the driver's seat and a rear seat etc.).

The development of semiconductor technology make simple audio and video system(such as traditional radio, CD, DVD etc.) become history, the latest requirements of automobile entertainment is, hope in car entertainment system can achieve the same effect with the home, and with flexible connected with consumer electronic products.Therefore, a single platform for automotive and portable communication equipment is a new topic facing the IC supplier.

At present the most recent advances have can be USB, MP3, Bluetooth, iPod and Dolbyinto the car. But it will need to provide the system structure is more complex and morehigh performance processor. As with other products in the field of consumption as (such as computer, home entertainment center, portable entertainment devices), the vehiclehas become a converged application, it will be through audio, video and data were pooled together for entertainment. In car entertainment center now to providenavigation, video and auxiliary driving application integration, also need to connect to provide individualized service, and to protect the file was not malicious content damage.In response to this request, Chinese electronic vehicle intelligent terminal Shanghai Chen to make full use of the powerful function of a single processor, to reduce the cost of remote information processing system, through the integrated many remote information processing tasks to a processing platform size and development time. A digital signal processor and a control processor i.mx536 is a powerful CPU, to support multiple standards and provide a variety of formats content to the car, and can provide a CAN bus and MOST bus connection.

Expensive and longer development time is the bottleneck of the development of the GPS system. I.mx536 is one of the solutions to these problems, in the GPS system, the performance of the i.mx536 can replace the processor subsystem provides a large number of independent processing ability, suitable for long distance communicationsystem developers.
