Drive design of GPS module and electronic compass module based on FPGA
Hongxi Xue · Electronic Design Engineering · 2011
GPS and electronic compass are an important part of geo-location positioning systems.To simplify product design and shorten the design cycle,in practical applications,customized GPS module and electronic compass module are usually used.However,it is not so efficient and most likely time-consuming when they are directly under the control of a DSP.The system performance would degrade as well.This paper presents a solution such that the GPS module and the electronic compass module are driven by an FPGA.In this method,the FPGA controls the GPS module and the electronic compass,as well as communicates with the DSP just by a high speed SPI interface.It been successfully implemented in the hardware platform,and made the software control of the DSP much easier and more efficient.
