Abstract
A signal processor includes at least one data source (3), a plurality of input registers (11, 12, 13, 14, . . . ) whose inputs are coupled to the data source by data buses (9, 10), a plurality of multipliers (19, 20; 71, 72 . . . ) for multiplying data buffered in the input registers, and a processing arrangement spread over a plurality of data processor branches (4-0, 4-1, . . . , 4-N) for processing products (p0, p1, . . . ), generated by the multipliers by arithmetic and/or logic operations. For achieving enhanced flexibility of the signal processor and increasing the number of possible applications, multiplexers (15, 16, 17, 18; 70) are provided which are used for coupling the multipliers to a respective part of the input registers in dependence on control signals (I, II, III, IV). Such a signal processor is preferably used in mobile radio technology. Further fields of application are, for example, audio, video, medical and automotive technology, ISDN systems, and digital radio.
