1 bit random number generator and many bit random number generator and probability generator

摘要

PROBLEM TO BE SOLVED: To easily verify the appearance uniformity of random number data and to improve reliability in a random number generator and a probability generator utilized in scientific and technical calculations or the like.;SOLUTION: The random number generator 2 outputting '1' and '0' as the random number data is provided with a first counter 3 counting the fixed number of times and a second counter 4 counting the number of times of the appearance of the random number data and generating the number-of-times data. A register 5 holds the number-of-times data of the second counter 4 for each cycle counted in the first counter 3 and an output circuit 6 outputs the number-of-times data held in the register 5 as verification data. Thus, the appearance uniformity of the random number data can be verified by itself and the need that a user perform a statistic processing is eliminated.;COPYRIGHT: (C)2003,JPO
