Abstract:
A data processing apparatus for performing common processing on musical tone data and image data comprising:a supply device that supplies original waveform data based upon which musical tone data are to be generated, and sounding control data containing kind information indicative of kinds of said original waveform data and pitch information indicative of pitches of said musical tone data, and supplies original image data based upon which image data are to be generated, and picture control data containing kind information indicative of kinds of said original image data and coordinate information indicative of coordinates of said image data on a display screen; a storage device that stores both of said original waveform data and said original image data supplied from said supply device; a common arithmetic processing device that performs interpolation processing or thinning processing on both of said original waveform data and said original image data, said common arithmetic processing device being operable upon receiving said sounding control data and said picture control data from said supply device, for reading out said original waveform data designated by said kind information of said sounding control data and said original image data designated by said kind information of said picture control data from said storage device, said common arithmetic processing device being operable for generating said musical tone data and said image data by subjecting said read original waveform data and said read original image data to said interpolation processing or said thinning processing according to said pitch information of said sounding control data and said coordinate information of said picture control data, respectively, said common arithmetic processing device being capable of processing both of said original waveform data and said original image data by processing in a time sharing manner; a musical tone buffer that buffers said musical tone data generated by said common arithmetic processing device to generate said musical tone data in a continuous form; and an image buffer that buffers said image data generated by said common arithmetic processing device to generate said image data in continuous form.
