Based on modern design technology of reconfigurable hardware,the hardware implementation of Kalman filter is studied.Applying plentiful resources of FPGA and its flexibility and parallel computation,according to the first timing later circuit mind,a floating Kalman filter is designed by using the top-down synchronous design method based on FPGA.Through analyzing the principle of Kalman filter,the design uses time-sharing multiplex technology in IP cores and modules to optimize the hardware structure.Finally,taking the precision improvement of the GPS as its application,the Modelsim simulation results show that the designed floating Kalman filter not only is real time,but also save resources and easy to realize,so it has practical value.
