摘要： The present invention provides a data processing method and device. A data processing device receives a first data stream, where the first data stream includes a first data unit; obtains a boundary of the first data unit; obtains a first skew according to a first data amount and the boundary of the first data unit; and adjusts the first data stream according to the first skew, so that a difference between the boundary of the first data unit and a boundary of the first data amount is a length of an integral quantity of first data units, so that a relatively small amount of data is needed in such an adjustment, that is, one data stream is adjusted, and an adjusted data stream can meet a basic condition for multiplexing, which reduces operation complexity and costs and is beneficial to deploy and implement bit width conversion.
