    Abstract: Disclosed is a device for generating a random number, comprising a unit (2) sampling a noise signal so as to obtain a noise signal sampling value. The random number generator also comprises a unit (5) supplying noise signal threshold values, the at least three noise signal threshold values being selected in such a way that a first probability that the noise signal sampling value lies between the first and the second noise signal threshold value is different by less than a predefined difference value from or identical to a second probability that the noise signal sampling value lies between the second and the third noise signal threshold value. A unit (3) issuing the random number operates based on the noise signal threshold values in such a way that a logical state is allocated to a first position of a random number if the noise signal sampling value lies between the first and the second noise signal threshold value while another logical state which is different from the first logical state is allocated to a second position of the random number such that one noise signal sampling value results in an at least 2-bit wide random number. Random numbers comprising any number of bits can be generated if more than three noise signal threshold values are used. The inventive device allows random numbers to be generated in a fast and efficient manner.

    Abstract: A processor arrangement comprises a number of processor units. Each processor unit is coupled to at least one adjacent processor unit by means of a bi-directional communication interface. Messages are exchanged between adjacent processor units for the determination of the separation of a processor unit in the processor arrangement from a reference position. Each message contains separation information, giving the separation of the processor unit receiving the message from the reference position or the separation of the processor unit sending the message from the reference position, where each processor unit is embodied such as to be able to determine or store the separation thereof from the reference position from the separation information in a received message.
