Abstract: A data conversion apparatus includes a conversion module, a frequency divider module electrically connected to the conversion module, and a clock selection module electrically connected to both the conversion module and the frequency divider module. The frequency divider module is configured to divide an input clock signal to obtain an output clock signal according to a bit-width m of input data and a bit-width n of output data. The clock selection module is configured to transmit the input clock signal and the output clock signal to the conversion module as a write clock signal and a read clock signal, respectively. The conversion module is configured to: receive the input data of m-bit-width according to the wire clock signal; convert the input data into the output data of n-bit-width; and output the output data according to the read clock signal.

Abstract: A software update method includes: receiving, by a target vehicle, first indication information, the first indication information being used to instruct to report version information of target software; sending, by the target vehicle, current version information of the target software configured on the target vehicle to a first control node currently establishing a communication connection with the target vehicle; further, receiving, by the target vehicle, second indication information sent by the first control node, the second indication information being used to indicate updated version information of the target software; and updating, by the target vehicle, the target software according to the second indication information.
