PURPOSE:To produce at a high speed and continuously the sequence data of an equal difference sequence equation which is useful as an address of the 2-dimensional array data every clock and in terms of a pipeline synchronously with the paired data which starts the production of data. CONSTITUTION:The paired data of the data name and data value is supplied through a signal line 1000, and a flag is supplied via a signal line 1005. A table part 100 contains a parameter output means which supplies the data names through a signal line 102 and reads out the parameter value corresponding to the data name among those parameters set previously for each data name to both signal lines 1003 and 1008. A data producing part 101 supplies both the data value of a signal line 1001 and the parameter value of the line 1003. A control part 102 supplies a flag of the line 1005 showing that the paired data is supplied through the line 1000 and outputs the produced sequence data to a signal line 1004. At the same time, a means is added to output an effective flag to a signal line 1006 for a period when the produced sequence data is kept effective on the basis of the parameter value fed from the line 1008.
