Abstract

The invention provides a batch out-of-order random number generation method based on a single-chip microcomputer. The method includes the steps that a random and no-repetition out-of-order data table with the length of 256 bytes is established, adjacent data in the out-of-order data table are not continuous, data in the out-of-order data table do not repeat, and the data are out of order; according to the length of random numbers to be generated, the number of out-of-order data tables to be produced is determined; a plurality of data seeds are obtained through random access memory data of the single-chip microcomputer; when the random numbers are generated in batches, each byte of data are made to change through a pre-determined algorithm. The random number generation mode is high in randomness, the random numbers in batches are generated, the adjacent data are out of order, and confusion caused by similarity is not prone to occurrence. Besides, the random numbers in batches will not repeat, and the method is an ideal method for generating out-of-order random IDs in batches.

Description

technical field [0001] The invention relates to the technical field of single-chip microcomputers, in particular, the invention relates to a method for generating random numbers in batches based on single-chip microcomputers. Background technique [0002] The existing method for generating random numbers by a single-chip microcomputer is prone to repetition, poor randomness, and requires a trigger source. And when batch generation, data will appear continuous or easy to repeat and other shortcomings. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for generating random numbers in batches out of order based on a single-chip microcomputer. When generating random numbers in batches, it has the characteristics of random numbers, non-repetition, and no need for triggering. [0004] In order to solve the above-mentioned technical problems, the present invention provides a method for generating batch random nu...
