PSEUDO-RANDOM NUMBER GENERATION CIRCUIT AND PSEUDO-RANDOM NUMBER GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pseudo-random number generation circuit which can generate a number having high randomness.;SOLUTION: A pseudo-random number generation circuit 100 comprises: a first generation circuit 10 which includes a shift register having a plurality of registers, and generates a first pseudo-random number having a plurality of bits which correspond to the plurality of registers, respectively; a second generation circuit 12 which generates a second pseudo-random number; and a selection circuit 14 which selects a bit to be output among the plurality of bits in the first pseudo-random number by using the second pseudo-random number, and outputs the selected bit.;COPYRIGHT: (C)2014,JPO&INPIT
