PURPOSE: To provide a digital signal processor capable of initializing necessary registers. CONSTITUTION: A signal processing program is stored in a microprogram register 11. The DSP repeats the signal processing program to perform processing of musical sound synthesis, etc. The signal processing program reads data out of an IRAM 21, a TRAM 22, etc., to a multiplier 26, an ALU 20, an accumulator 17, etc., to perform arithmetic processing, writes out data on the arithmetic result to an output port, and also writes the data back to the TRAM 21 and TRAM 22 to use them as delay data. Therefore, input data and the arithmetic result data are circulated between the IRAM 21 and TRAM 22 of a register group, and accumulator 17. Values inputted to the accumulator 17 and the register group are initial values selected by the multiplexer 16 and the signal processing program is utilized to initialize the necessary registers. |
