Methods and systems for synchronization of slave device with master device

Abstract:

Methods and systems for synchronizing a slave device with a master device are disclosed. The method includes arranging a bitstream of data into a two-dimensional frame having a plurality of columns and rows. The method further includes searching the columns for an occurrence of an 8-bit static sync word having a constant sync value. The total number of columns of the two-dimensional frame is equal to the number of columns of a group containing the 8-bit static sync word. The method also includes re-aligning the two-dimensional frame by shifting and re-numbering the column having the 8-bit static sync word to column zero. The method also includes determining the number of rows of the re-aligned frame and synchronizing the slave device with the master device based on the re-aligned frame and the number of columns and rows of the two-dimensional frame.
