Abstract
A multi-channel signal processing apparatus comprises a memory unit, a signal processing unit for single-channel implementing predetermined signal processing using a memory region of the memory unit according to a signal processing program for single-channel, an address generation unit generating a first memory address for single-channel processing, a pointer adding unit adding a pointer value indicating the head of an unused memory region of the memory unit to the first memory address generated by the address generation unit each time the signal processing in the signal processing unit is completed to generate a second memory address, and an address selecting unit selecting either the first memory address or the second memory address as a real address for the memory unit, thereby enabling multi-channel signal processing having a high processing efficiency without adding a large modification to the signal processing program for single-channel.
