Abstract
PURPOSE: To bring excellent signal processing to effect by letting a digital signal processor, using a stored program, operate at its original processing speed without reference to whether a control data write instruction exists to send control data to a processing circuit according to the existence of the write instruction.
CONSTITUTION: Memory 8, when write command signal wp is not supplied to terminal W/R, outputs control data stored at read address (ar) from address output terminal AO of processing circuit 9 to terminal CI of circuit 9. On the other hand, when signal wp is supplied to terminal W/R, control data (dw) from terminal 2 is written at an address assigned by address (ar) while data (dw) are output, and circuit 9 processes input signal Si from terminal SIP on the basis of data (dw) and outputs the processing result data to terminal 5. Consequently, circuit 9 operates at its original processing speed without reference to whether signal wp control data write instruction (w) exists and also inputs control data (dw) to the processing circuit according to the existence of write insturction (w), performing excellent signal processing.
