Title: Random number generator and random number generation method
Inventor: TAKATSU MOTOMU
IPC: G06F7/58
Filed: 2019-07-17
Abstract: To reduce the number of pseudo-random numbers to be used to generate a plurality of normal random numbers.SOLUTION: A pseudo-random number generator 11 generates a plurality of pseudo-random numbers (x0 to xn-1). An orthogonal transformation circuit 12 generates a plurality of normal random numbers (y0 to yn-1) by orthogonally transforming the plurality of pseudo-random numbers (x0 to xn-1). Since the normal random numbers are generated by the orthogonal transformation, the number of the obtained normal random numbers becomes equal to the number of the pseudo-random numbers generated by the pseudo-random number generator 11. Therefore, the number of pseudo-random numbers to be used to obtain a plurality of normal random numbers can be reduced as compared with a case where normal random numbers are simply generated by the central limit theorem using an adder circuit or the like.SELECTED DRAWING: Figure 1
