Implementation of adaptive Ethernet for embedded integrated navigation system

Integrated navigation is the focus research in the navigation field. With the rapid development of electronic technology, the embedded technology is widely application in the integrated navigation system. The system is demand real-time, so that the high quality and rapid communication between the system and the peripheral devices is necessary. In the integrated navigation system, DSP is used to process the navigation information, and FPGA is used to control the peripheral devices. This paper adopts the w5300 as the adaptive Ethernet chip which bottom driver is used TI C6000 DSP operates and used FPGA control the reset signal. Practice proves that this design is effective and reliable meet the real time constraint and meet the embedded integrated navigation system small volume and low power dissipation demand.
