【Abstract】 This paper studies the precision threshold of chaotic sequences.The results of simulation showed that the precision of classical chaotic sequences is very high.At present several modified methods of Logistic chaotic sequence decrease the need for precision obviously.These methods are analyzed and compared and the shrinking method with the best performance is improved,which can decrease calculation volume obviously.Furthermore,it is easier to realize in hardware than conventional chaotic sequences.更多还原
