Abstract

A digital signal processing device features that it has sound signal processing as goal, parameter supplying means for supplying necessary parameters, and multiple independent digital signal processing means. Each one of the multiple digital signal processing means, according to the procedure of setting the input parameter, applies decided algorithm operation to digital input data, then outputs processed data. parameter input means including the first bus that is commonly connected to the above each digital processing means, distributing each of the above multiple parameters supplied from the above parameter supplying means to decided digital signal processing means through the first bus; data transferring means including the second bus that is commonly connected to each of the above multiple digital processing means, transferring output data from the above digital signal processing means through the second bus; in at least one of the above digital signal processing means, getting output data from the other the above digital signal processing means through the second bus, then applying the above algorithm operation with the got data as input data. Therefore, by algorithm operation combination of the above multiple digital signal processing means, performing sound signal processing with the above as goal, resulting that the processed sound signal acts as output data of digital signal processing means of the above multiple digital processing means and gives to the above second bus.
