Data transfer unit and data transmission method based on data transfer unit

Abstract

The invention discloses a data transfer unit and a data transmission method based on the data transfer unit, and relates to the field of unmanned driving. The data transfer unit can perform data transmission with a first data processing unit and at least one second data processing unit through a data bus; different second data processing units can be in communication connection with different hardware devices, the data transfer unit comprises a data distribution unit and a plurality of data register units, data corresponding to the different second data processing units are stored in different data register units, and the data are stored in the data register units. The data distribution unit can receive data sent by the first data processing unit or the second data processing unit, determine the second data processing unit corresponding to the received data as a target data processing unit, and store the received data in the data register unit corresponding to the target data processing unit. Therefore, communication can be carried out on multiple hardware devices at the same time.

Description

technical field [0001] This specification relates to the field of computer technology, in particular to a data transfer unit and a data transmission method based on the data transfer unit. Background technique [0002] In practical applications, data transmission is often required inside the driving device (unmanned driving device or conventional driving device, etc.), for example, the main controller of the unmanned The control machine needs to communicate with hardware devices such as vehicle motion, headlight-related controllers, and millimeter-wave radars to monitor the vehicle motion status and issue control commands. [0003] In the prior art, the driving device can send data to the chip that communicates with the vehicle-mounted device through an instruction signal, so that the data that the chip needs to send to the vehicle-mounted device is sent to the vehicle-mounted device, and the vehicle-mounted device needs to send data to the vehicle-mounted device. The data ...
