Abstract
The invention discloses a data bus flipping circuit and method, and the circuit comprises a DBI calculation circuit which calculates a data flipping signal corresponding to the current input data; the DBI mask generation circuit is used for receiving an input data overturning signal, calculating the number of data needing to be overturned in the input data according to the data overturning signal, comparing the number of the data needing to be overturned with a preset value, and outputting a corresponding mask signal; and the data processing circuit is used for processing the to-be-transmitted data based on the mask signal and determining whether the to-be-transmitted data needs to be overturned or not. According to the data transmission method and device, whether data bus overturning is started or not is controlled through the mask signal when a large amount of data is continuously transmitted, and the power loss during data transmission is reduced by reducing unnecessary overturning.
