Abstract
A method and apparatus are provided for decoding variable length codewords carried in data blocks. A first buffer is loaded with a succession of data blocks. A second buffer is loaded with a first data block from the first buffer during a decoding cycle. The variable length codewords from the first data block in the second buffer are decoded to recover information. The process continues, with the second buffer being loaded with one data block at a time to successively decode new data blocks during successive decoding cycles.
