摘要： A variable length decoder device receives a stream of variable-length encoded data segments for successive transient storage. The storage is recurrently accessed under control of successive pointers. A decoder is fed by the storage and decodes a stream of data segments each from a respective encoded data segment. Furthermore, in step with the decoding a next pointer is produced as being directly derived from the accessing through reading of a localizer information. The latter again is produced in a preprocessor that sits before the storage, through localizing the data segments and indicating each segment by an associated localizer.
