ABSTRACT:
A data decoder is described for decoding interleaved first type code words [RUNLENGTH, SIZE] and second type code words [AMPLITUDE], each first type code word serving to define a runlength of constant values preceding a variable value defined by a following second type code word. The first type code words and the second type code words are fed to respective first and second pipeline delay units 22 and 24. The output from the first pipeline delay unit 22 is fed to a state machine 26 which reads the RUNLENGTH value and generates an INSERT ZEROS signal for a period proportional to the RUNLENGTH value followed by a signal triggering reading of the second pipeline delay unit 24. The INSERT ZEROS signal and the output of the second pipeline delay unit 24 are fed to a multiplexer 28 which selects between them to generate the appropriate OUTPUT signal. A swing buffer 10 is disposed upstream of the first and second pipeline delay units 22 and 24. The second pipeline delay unit 24 is also used to effect fixed length code decoding.
