The processor adopts a maximum main frequency of 2GHz, quad-core, 64-bit, Arm®Cortex®-A55 architecture, and integrates a variety of powerful functions such as G52 GPU and 1 Tops computing power NPU. The processor has a built-in 3D GPU, supports almost all formats of H.264 4k@60fps decoding, supports H.265 4k@60fps decoding, and also supports H.264 / H.265 1080p@60fps encoding, as well as high-quality JPEG encoding / decoding, and is fully compatible with OpenGL ES1.1 / 2.0 / 3.2, OpenCL2.0 and Vulkan 1.0, the dedicated 2D hardware engine will maximize display performance and provide a smooth operating experience, and the processor's embedded NPU coprocessor unit supports INT8 / INT16 mixed operations. In addition, with the powerful compatibility of NPU, network models based on a series of frameworks such as TensorFlow / MXNet / PyTorch / Caffe can be easily converted.

[0027] The memory uses DDR4*2, the storage uses 4GB, 8GB and 16GB EMMC, the direct read memory is 4G, the electronic storage is 16G, and the main control module also includes WDT and E045. WDT has an input and an output to the RST end of the MCU. When the MCU is working normally, it outputs a signal at regular intervals to clear the WDT. If the specified time is exceeded, the WDT timing is exceeded, and a reset signal will be given to the MCU to reset the MCU to prevent the MCU from crashing and preventing the program from having an infinite loop.

[0028] The communication module is connected to the main control module by signal. The communication module includes a communication interface and DTU, which are used to receive and send satellite signals. The communication interface includes USB, USB2.0 HOST, two Gigabit Ethernet interfaces, WIFI socket, CAN socket, RS485 socket and 232TTL socket. The main control module is connected to the 232TTL socket through USART. The main control module is connected to DP83867 through RGMII, and then connected to the Gigabit Ethernet interface through DP83867. DP83867 is a robust, low-power, full-function physical layer transceiver. It integrates the PMD sublayer to support 10BASE-Te, 100BASE-TX and 1000BASE-T Ethernet protocols. RGMII is used to connect Ethernet MAC and PHY. Through a variety of communication interfaces, it can expand the data exchange with other devices and modules.

[0032] The main control module is connected to the RTC through IIC. The RTC can ensure that the system has accurate time information, which is used to record the occurrence time of specific events and implement timed operations, such as timed wake-up and timed tasks. It can also synchronize time with other systems or devices to facilitate the management and processing of date and time, add time stamps to data, facilitate data analysis, avoid problems caused by time errors, and assist in system monitoring and fault diagnosis.

[0033] The main control module is connected to the debugging serial port through DUART. The debugging serial port can monitor the data in real time during system operation, help developers understand the working status of the system, and then quickly locate and troubleshoot faults, improve development efficiency, and conveniently set and adjust parameters. It verifies whether the communication between the system and other devices is normal, debugs and optimizes the code during the development process, and records the system's operation log for subsequent analysis and problem tracing, and realizes remote monitoring and control of the system, thereby improving the stability and reliability of the system.

[0034] The power module is electrically connected to the main control module and is used to provide power for the main control module, communication module, display module and feedback module; the power module includes PowerManager, and the power input range of the power module is 9 to 36 volts DC.
