FPGA application of marine navigation system for DSP

This paper discusses how a marine navigation system works with FPGA. Some difficulties, such as converting coordinates, overcoming the blind points, synchronizing the clock, superimposing the display layers, are indicated. Only two chips of FPGA cover most of the functions, and that shows the ability of the integration and flexibility. At a further extent, it is the FPGA, but not instructive CPU, that deals with DSP. It implies a promising domain of the FPGA application
