Abstract:
1. Digital signal processing apparatus, comprising: input means for inputting a plurality of acoustic signals from an external outputting device; a plurality of digital signal processing units electrically connected with one another in series to form a closed loop, said digital signal processing units receiving and processing data elements including said acoustic signals as shared data elements in a sequential order; and output means for outputting a plurality of acoustic data elements processed and generated by said digital signal processing units to an external inputting device, each of said digital signal processing units comprises: receiving means for receiving said shared data elements from a preceding digital signal processing unit; received data storing means for storing said shared data elements received by said receiving means into a receiving memory; copied data storing means for copying said shared data elements stored in said receiving memory to a shared memory section; acoustic signal processing means including one or more acoustic signal processing sections each for inputting said shared data elements stored in said shared memory section as an input signal, processing said shared data elements thus inputted, and writing an output signal into said shared memory section as shared data elements; transmitting data storing means for storing shared data elements stored in said shared memory section into a transmitting memory; transmitting means for transmitting said shared data elements stored in said transmitting memory to a subsequent digital signal processing unit; and shared data editing means for editing said shared data elements stored in said shared memory section.
