RANDOM NUMBER GENERATION CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a random number generation circuit of small circuit scale, capable of freely changing the tap position of a pseudo random number series such as M-series.

SOLUTION: The random number generation circuit comprises a linear feedback shift register generating pseudo random numbers of pseudo random number series; a register storing a tap position in the pseudo random number series; and a feedback signal generation circuit generating a feedback signal to the linear feedback shift register based on data stored in the linear feedback register and the tap position stored in the register.
