Design and implementation of Kalman filter based on FPGA

The calculation precision and speed of Kalman filtering are the key factors in application.Aiming to improve the performance of Kalman filtering algorithm applied to a more complex condition and meet the requirements of high accuracy and real-time performance,a scheme for implementing the Kalman filtering algorithm was designed with FPGA technology.Some key techniques such as the multiplication of matrixes,the application of finite state machine and the same source usage at different time were designed.The superiority of implementing the Kalman filter in FPGA was validated by comparing the verified results of Kalman filter implemented in FPGA with the calculated results of Matlab and DSP respectively.
