Abstract
In one embodiment, a data decompression circuit for a data stream having a repeated data word is provided. The data stream is compressed into a series of data frames such that the repeated data word is removed from the series of data frames and such that each data frame corresponds to a header. The circuit includes a decompression engine configured to decompress each data frame into a corresponding decompressed data frame, the decompression engine being further configured to decode each header to identify whether word locations in the corresponding decompressed data frame should be filled with the repeated data word.
