The optimal form of integer dynamic tent map is used as the nonlinear function of lattice point based the couple map lattice model, which can generate quickly the pseudo random sequence with uniform distribution and independence. The information entropy, mutual information, difference characteristic, Lyapunov exponent and randomness of the model are simulated and analyzed. The simulation results indicate that the integer dynamic tent map is completely equivalent to the optimization model, which satisfies the performance requirements of generating pseudorandom sequences, and the efficiency of generating is significantly improved. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1804-0119
