A digital signal processor and digital signal processing method are provided, which are capable of performing plural kinds of signal processing, and also performing processing for storing sampled data in a manner corresponding to respective kinds of signal processing with a small amount of hardware even in the case where the manner of storing and reading sampled data to be processed with respect to a memory device is different between the plural kinds of signal processing. A storage device stores plural kinds of sampled data corresponding, respectively, to plural kinds of signal processing. A counter updates a count value thereof every sampling period and generates the updated count value as a basic address. A sampled data input and output device performs an input and output operation every sampling period, the input and output operation comprising generating plural kinds of offset addresses corresponding, respectively, to the plural kinds of signal processing and not overlapping with each other, generating at least one write address or read address for the sampled data for each of the plural kinds of signal processing by modifying the basic address by at least one of the offset addresses corresponding to each of the plural kinds of signal processing, and delivering the generated at least one write address or read address to the storage device.
