Abstract: In order to meet the requirement of marine laser gyro inertial navigation system, this paper designs a navigation computer system based on the DSP chip named TMS320C6713B and FPGA. By using FPGA, the count functions of the signal of laser gyro and the output signal of accelerometers are realized, and the communication between DSP and peripheral equipment is accomplished. This system has the structure of single CPU using TMS320C6713B as the core. It can do operation with 64 bit precision and high speed and meet the needs of real-time performance.
