Abstract :
In order to improve the processing speed of navigation computer, a CPLD-based design of preprocessing circuit is presented. The outputs of gyroscopes, accelerometers, odometer and GPS are pre-processed, and then exchanged with the signal processing circuit through a dual-port RAM. All the information pre-processing circuit is designed in the CPLD, which enables a more flexible using and simpler circuit composition.
