Abstract:
A multi-channel signal processing apparatus comprising:a memory unit; a signal processing unit, for single-channel and shared with multi-channel signals, to process the individual multi-channel signals using a memory region of said memory unit according to a signal processing program for single-channel; an address generation unit to generate a first memory address for a first memory region of said memory unit, which region is used for common signal processing common to the multi-channel signals according to said signal processing program; a pointer adding unit to add a pointer value indicating the head of an unused memory region of a second memory region of said memory unit, which region is used for individual signal processing independent for the individual multi-channel signals, to said first memory address generated by said address generation unit each time the single-channel signal processing in the signal processing unit is completed so as to generate a second memory address; and an address selecting unit to select either said first memory address or said second memory address as a real address for said memory unit according to whether the signal processing to be implemented in said signal processing unit is the common signal processing or the individual signal processing.
