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 occurance 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.

Abstract: A system and method for performing speaker load diagnostics. A digital signal processor generates a diagnostic tone that is provided to the speaker. The diagnostic tone is generated using an oscillator internal to the digital signal processor. The digital signal processor receives current and voltage data from the speaker based on the diagnostic tone, and processes the current and voltage data to determine whether a fault condition exists in the speaker.
