PURPOSE:To obtain a concise control structure, by adopting a system which adds a control bit to each of a series of input data, and decides a processing operation to the data concerned by said control bit. CONSTITUTION:In case of controlling a data output, control data are set to a data buffer read-out control data register 23. The control data are decoded by a decoder 25, and set a processing mode and a storage unit access address to a processing hardware 26. The processing hardware 26 reads out a data from a storage unit 38 in accordance with the processing mode and the storage unit access address, which have been set, executes a necessary processing, sends out a processed data to an output data interface 36 through an output data transmitting interface 35 and an output data transmission controlling circuit 27, and completes a series of output data processing. |
