The first data conversion module 523 is connected to the data acquisition module 516 and the serial interface 111, and is configured to convert data acquired by the data acquisition module 516 and send the converted data to the host device 2 through the serial interface 111.
As shown in fig. 6, the data collection module 516 may include, for example: a global shutter camera (global shutter camera) 5161, an IMU (Inertial Measurement Unit) 5162, and an RGB camera 5163.
Data can be transmitted between the first data conversion module 523 and the RGB camera 524 between the global shutter camera 5161 and the first data conversion module 523 through MIPI interface specifications.
The MIPI interface specification is an open standard and a specification established for mobile application processors initiated by the MIPI alliance. The purpose is to standardize the interfaces in the mobile phone, such as a camera, a display screen interface, a radio frequency/baseband interface and the like, thereby reducing the complexity of the mobile phone design and increasing the design flexibility. The MIPI multimedia specification is largely divided into three layers, namely an application layer, a protocol layer and a physical layer. The Interface is mainly applied to interfaces of equipment such as a Camera, a Display and the like, wherein the interfaces include a Camera Interface CSI (Camera Serial Interface), a Display Interface DSI (Display Serial Interface) and the like.
Data can be transmitted between the IMU 5162 and the first data conversion module 523 via the SPI bus.
The SPI bus is a high-speed, full-duplex synchronous communication bus. The SPI communication principle is simple and it works in a master-slave mode, which usually has a master and one or more slaves, requiring 4 lines for master data input, master data output, clock signal transmission, and enable signal transmission for master output, respectively. Usually, the SPI interface is also a control interface for transmitting control signaling.
The first data conversion module 523 converts data received from the global shutter camera 5161, the IMU 5162, and the RGB camera 5163 into serial data suitable for transmission by the serial interface 111.
The second data conversion module 524 is connected to the display switching module 113 and the serial interface 111, respectively, and is configured to convert data received through the serial interface 111 into first display data, and send the first display data to the display module 114 for display.
The second data conversion module 524 may, for example, convert serial data received from the serial interface 111 into data conforming to the MIPI DSI interface specification, so as to send the converted first display data to the display module 114 for display through the MIPI DSI interface specification.
