Loongson-based CPCI (Compact Peripheral Component Interconnect) domestic vehicle-mounted computer

The invention provides a Loongson-based CPCI (Compact Peripheral Component Interconnect) domestic vehicle-mounted computer. The Loongson-based CPCI domestic vehicle-mounted computer The CPU board is provided with a plurality of CPCI interfaces, and the plurality of CPCI interfaces are respectively connected with a CAN communication board for realizing CAN communication, a COM board for receiving and transmitting serial port data, an AD board for supporting analog-to-digital conversion and a DA board for supporting digital-to-analog conversion; the CAN communication board, the COM board, the AD board and the DA board all take FPGA chips produced in China as main control chips; the core main control chip of the CPU board is a Loongson chip. Based on the Loongson chip design, foreign computers can be equivalently replaced in the field of special vehicle-mounted computers; the microcontroller has the capability of working in a severe environment, and can effectively solve the problem that many microcontrollers ca
