FIXED-POINT MULTIPLIER OF LOGISTIC MAPPING

摘要

PROBLEM TO BE SOLVED: To obtain the permutation and combination needed for solving complex combination problems by replacing the carry of a fixed-point multiplier of logistic mapping with serial bit operations, and generating pseudo random numbers at high speed.

SOLUTION: The multiplication xt(1-xt) of logistic mapping creating chaos is the multiplication of an integer xt and its inverted plus-one complement. For shifted serial additions, the additions are replaced with bit operations.
