Dual-CPU embedded navigation computer

The invention provides a dual-CPU embedded navigation computer, composed of a MCU module, a PC104 module, an A/D conversion module, a dual-port RAM data share module, a complex programmable logic device decoding module and a serial communication interface module. The IMU inertial sensor information is processed by A/D conversion into digital values to be input into the MCU module, buffered by the dual-port RAM and fed into the PC104; GPS and electronic compass navigation information are directly fed into the PC104 via interface circuit to process navigation data fusion, the calculation result is transmitted to external system via interface circuit or visually displayed via a man-machine interaction interface of the system; the data acquisition is completed under the combination control of the MCU module and the CPLD decoding module. The invention has the advantages that: (1) the dual-CPU embedded navigation computer has high navigation information processing speed; has many data acquisition channels; (3) has strong communication ability; (4) has small volume low cost, high reliability, simple operation and simple man-machine interaction.
