Abstract
Description
technical field
[0001] The invention relates to an embedded multimedia intelligent GPS navigation device, in particular to an embedded multimedia intelligent GPS navigation device with a micro hard disk as a carrier. Background technique
[0002] Conventional vehicle-mounted GPS navigation system devices use X86 CPU as the system processor, which causes the whole device to have disadvantages such as high cost, poor thermal performance, and weak interface expansion capability. The other is to use a dedicated chip as the central controller, such as Although Japan's SH-4 has strong functions, its cost is too high, and its development and expansion are limited by many conditions. For this reason, this system uses the embedded CPU of ARM core technology as the system processor, which is not only low in cost, but also power-saving. , good thermal stability, strong expansion ability, easy to achieve productization and other advantages.
[0003] On the other hand, conventional navi...

Embodiment Construction
[0036] Such as figure 1 Shown is the overall device structure of the embedded multimedia intelligent GFS navigation device of the present invention
[0037] block diagram. It includes a GPS module 1, a microhard disk 2 for storing streaming media, a multimedia control panel 3 for decoding streaming media, a display module 4 for displaying streaming media or navigation interfaces, and the aforementioned modules are connected to the main board 5 for navigation. The mainboard 5 can read streaming media information from the microhard disk 2 and send it to the multimedia control board 3 for decoding. After decoding, the streaming media is sent to the display module 4 for display. The navigation mainboard 5 can also provide GIS signals.
[0038] Among them, the embedded navigation motherboard 5 adopts a set of chips designed by Inter based on ARM9 generation and XSCale architecture.
[0039] Among them, the multimedia control board 3 adopts a dedicated decoding chip, which has a s...
