Frame decoding method in JESD204B protocol

The invention relates to a frame decoding method in a JESD204B protocol. The method comprises the following steps that: according to a pre-input parameter, determining data bit width output after frame decoding is carried out; according to pre-determined octets in each frame, judging a form for extracting data from each channel, i.e., extracting the data according to a byte form or a character form; on the basis of a judgment result, carrying out extraction and sorting processing on the character data or the byte data of each channel to obtain the character data subjected to the sorting processing; reducing the character data subjected to the sorting processing into the sample data of each converter; and according to the data bit width, combining the sample data of each converter, and outputting the combined data. By use of the frame decoding method in theJESD204B protocol, a frame decoding process can be realized according to the requirements of the JESD204B protocol. 本发明涉及种JESD204B协议中解帧的方法，所述方法包括：根据预先输入的参数值
