Abstract
A sound processor is formed on a single semiconductor device and has a function as a bus master for a common bus to positively and effectively access a resource on a common bus. Outputted is data over N sets (N being a natural number greater than 2) of sound channels through time division multiplexing to M sets (M being a natural number) of independent digital/analog converting means for converting sound-channel digital data into an analog sound signal. This reproduces pulse-code-modulated sound waveform data capable of simultaneously reproducing over a plurality of sets of sound channels represented by a product of M and N.
