Abstract
A digital signal processor performs a predetermined operation on a digital signal based on data, such as coefficient parameters and programs, and outputs the processed digital signal to an external reproducing device. The digital signal is processed during a signal processing period and data is transferred and rewritten during an information transfer period. The digital signal processor generates a reference processing cycle having a period longer than the signal processing period and the information transfer period combined. The length of the signal processing period and the information transfer period are adjusted within the reference process cycle, and the signal processing and data transfer are performed in a time sharing manner via a common internal bus. When data is changed, the digital signal is outputted without being processed to an external reproducing device to maintain the continuity of the signal output. As a result, data required for the signal processing can be replaced without interrupting the output of the signal.
