Abstract

An application-specific integrated circuit comprises: analog inputs having analog-digital converters; at least one digital signal processor, which has input registers and output registers. The analog-digital converters sample and digitize input signals Si with sampling frequencies fSi and forward the digitized signals SDi with output frequencies fSD-out-i to the input registers of the digital signal processor. The digital signal processor processes the digitized signals SDi to m processed signals SPj and forwards such to the output registers of the digital signal processor. The digital signal processor has a clock frequency, wherein, furthermore, the signals of the output registers can be output, respectively read-out, with an output frequency. One or more of the frequencies is, respectively, variable, wherein especially one or more of the frequencies, respectively, variable independently of the others of the frequencies.
