摘要

PROBLEM TO BE SOLVED: To decode sound data encoded by the encoding systems of different standards by absolute minimum circuits and to perform a delivery processing to a D/A converter.;SOLUTION: In the case of decoding the sound data encoded by the encoding system of a specified standard (for instance, the ADPCM(adaptive differential pulse code modulation) system of the different standard), the sound data are rearranged beforehand by a data rearrangement means 102 and stored in a second data storage means 103 and the sound data read from a third data storage means 105 are decoded by a decoding means 107, converted from parallel data to serial data in a parallel/serial data conversion means 109 and delivered to the D/A converter. Thus, without the need of this sound controller for each encoding system, the decoding of the encoding system of the different standard and the delivery processing to the D/A converter are performed by small-scale circuit change.;COPYRIGHT: (C)2000,JPO
