ABSTRACT:
A plurality of parallel processing devices such as compression/decompression units can be tied together to sequentially process equal amounts or sets of data from a stream of data. Hardware in the upper level of each device acts as a demultiplexer to control the acceptance of only its set of data to transfer control to permit the next device to accept data and also stores its set for compaction. Essentially identical hardware in the lower half of each device acts as a multiplexer to control the acceptance of its compacted set of data to store the compacted set and to place the compacted set into the original sequence of the stream of data for storage on the tape media. The lower half reverses its role when the compacted set of data is retrieved from the media to act as a demultiplexer for the decode sequence while the upper half acts as a multiplexer to resequence the decompacted sets into its original stream.
