Abstract
If an input word bit includes overhead data, the input word bit is ignored. If the input word bit includes non-overhead data and the corresponding bit position in a first buffer is empty, the non-overhead data is stored in the corresponding bit position in the first buffer, and the corresponding bit position in the first buffer is marked as full. Otherwise, the non-overhead data is stored in the corresponding bit position in a second buffer, and the corresponding bit position in the second buffer is marked as full. When all bit positions in the first buffer are marked as full, the data is shifted out of the first buffer, rotated to be in data arrival sequence, and made available for further processing. Then, the data in the second buffer is transferred to the first buffer, and the bit positions in second buffer are reset to be marked as empty.
