Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a DSP, e.g. an FIR filter, capable of compressing the memory capacity of an ROM for storing various programs. SOLUTION: An input stage DSP2 being disposed on the input side, an output stage DSP4 being disposed on the output side, and an intermediate stage DSP3 interposed between the input stage DSP2 and the output stage DSP4 are connected sequentially in cascade. These DSPs are arranged to store inherent programs P1, P2 and P3, respectively, and a common program Pc shared by the DSPs. COPYRIGHT: (C)2004,JPO
