Digital signal processing device capable of selectively imparting effects to input data

A digital signal processing device comprising:

• program supply means for supplying at least two kinds of programs, each consisting of a plurality of steps, alternatively, each of the microprograms including microinstructions for performing an effect-imparting calculation, and at least one of the microprograms including microinstructions for performing a line connection calculation between said effect-imparting calculations;
• computing means for performing digital computing, using data supplied thereto, in accordance with the at least two kinds of program;
• data storing means for storing the data supplied or results of the digital computing performed by the computing means;
• and
• control means for controlling operations of the data storing means with the control means being instructed by both of the at least two kinds of programs.

A digital signal processing device comprising:

• input means for inputting first data supplied thereto during each sampling cycle;
• microprogram storing means for storing first and second microprograms, each consisting of a plurality of microinstructions for performing an effect imparting calculation;
• selecting means for automatically selecting one of the first and second microprograms in accordance with a preset sequence of processing;
• arithmetic means for performing arithmetical operations in accordance with the microprogram selected by the selecting means;
• storage means for storing second data representative of results of the arithmetical operations which have been performed during each sampling cycle by the arithmetic means;
• output means for outputting third data representative of result of the arithmetical operations of the second microprogram during each sampling cycle;
• and
• data supply means for when the first microprogram is selected, supplying the first data to the arithmetic means so that the arithmetic means performs the arithmetical operations using the first data and for when the second microprogram is selected, supplying the second data stored during a preceding sampling cycle to the arithmetic means so that the arithmetic means performs the arithmetical operations using the second data.
