Data formatter for formatting variable length data words into fixed length data words

摘要

A two stage data formatter is described for converting variable bit length code words into fixed bit length code words. The second formatting stage 12 splits the words into complete fixed length code words and returns any remainder bits to the first formatting stage 10. The first formatting stage 10 preprocesses the following data words by concatenating any remainder bits with the following variable bit length code word and updating its corresponding bit length code word. These preprocessed data words are then passed to the second formatting stage 12.
