Design Navigation Computer System Based on Double Digital Signal Process and FPGA

The article describes the design and implementation of integrated navigation embedded computer system based on double DSP and FPGA. In the system, TMS320C6727 (C6727) and TMS320C6713 (C6713) digital signal processor (DSP), which produced by TI are used as the core processing chip. C6727 is responsibility to de-noising the inertial measurement unit (IMU) original signal, and send the IMU data to C6713. C6713 is responsibility to collect the IMU and GNSS data, run navigation algorithm and send the navigation information to other implements. The I/0 interface, timing control, data buffering and address bus decoding modes are implemented in FPGA. This design can improve the system real-time performance and reliability.
