Abstract

PURPOSE:To ease a request for speed to a circuit component element, by carrying out a detection of word length over n words and then controlling a matrix within the n basic time slot to obtain an output in case the fixed length code is converted into the variable length code. CONSTITUTION:The input data having a fixed length is applied to the matrix MT11. The MT11 turns the fixed length code data so that a coincidence is obtained between the highest-rank bit of the output of the MT11 and the head of the next variable length code excepting the vairable length code that is through with the process already in the preceding action among the input fixed length code data by the input of the first basic clock CK and under the control of the control circuit 13. The vairable length code data of a word of the higher-rank bit in the MT11 is read into the FF14. At the same time, the word length detecting circuit 12 performs a word length detection for the output of the TM11 over n words. When the next basic CK is supplied, the contents of the FF14 is read into the FF16. The contents of the FF16 is read by the next basic CK to deliver the data composed of a variable length code.
