ABSTRACT:
A digital signal processing device (e.g., DSP), employed by electronic musical instruments and the like, is designed to perform a variety of digital signal processings. The digital signal processing device contains an arithmetic unit which is configured by at least an adder and a multiplier. There are provided first and second microprograms, each of which consists of microinstructions and each of which is designed to perform a specific kind of digital signal processing. The first and second microprograms are alternatively selected in accordance with a preset sequence of processing; and consequently, data supplied to the arithmetic unit are changed in response to the microprogram selected. Thus, the arithmetic unit performs arithmetical operations, using the data selectively supplied thereto, in accordance with the microprogram selected. By changing the sequence of processing, it is possible to easily change a manner of digital computing performed by the digital signal processing device. For example, the first and second microprograms are executed successively in a serial manner or are executed simultaneously in a parallel manner. Preferably, the first microprogram is designed to impart distortion to the data, while the second microprogram is designed to impart reverberation to the data.
