A method and circuit arrangement for detection of measured values with a digital signal processor with an integrated analog / digital - transducer

摘要

The present invention relates to a method and a circuit arrangement for detection of measured values with a dsp (10) with an integrated a / d - transducer (11), wherein the dsp (10) with an external memory module (20) is connected and a control input (15) for controlling access to the external memory module (20) comprises. The method is distinguished by the fact that a signal to a digital output (16) of the dsp (10) is output on the control input (15) of the dsp (10) is fed back, so that an access to the external memory module (20) for at least the duration of one of the measurands by the a / d - transducer (11) is prevented. In the case of a suitable for carrying out the process circuit arrangement, the digital output (16) of the dsp (10) directly or indirectly to the control input (15) of the dsp (10) a.
