PURPOSE:To improve the accuracy of numerical data handled at a a microcom puter by improving the resolution of numerical data transferred from a DSP (digital signal processor) to the microcomputer for control concerning the audio signal processor for executing a digital operation processing. CONSTITUTION:At the audio signal processor, for which the processing data length of the DSP is larger than that of the microcomputer at least, equipped with a DSP 2 to execute the prescribed digital operation processing to audio signals and a microcomputer 24 to exchange data with the processor, only numerical values are transferred without containing positive and negative sign bits S concerning the numerical data when transferring the data from the DSP 2 to the microcomputer 24. |
