Abstract

The invention provides a random sequence generation method and device with controllable time statistical distribution. The method comprises the following steps: generating a random number according to an obtained random bit stream; generating a time domain analog signal according to the signal output by the time-containing function; generating a random sequence with a time distribution characteristic according to a comparison result of the random number and the time domain analog signal; wherein the random number is a random number distributed in an interval of [0, 1]; the time domain analog signal is an analog signal distributed in a [0, 1] interval. According to the method and the device for generating the random sequence with the controllable time statistical distribution, the random sequence with the controllable time statistical distribution can be generated, the requirement on the stability of the trigger clock is low, and the method and the device have good fault tolerance and robustness.

Description

technical field [0001] The present application relates to the field of random number generation, and in particular, to a method and device for generating random sequences with a controllable time statistical distribution. Background technique [0002] At present, mainstream computers adopt the von Neumann architecture, and use serial instructions to perform various computing operations to complete specific tasks. From the perspective of computing principles, it belongs to deterministic computing, that is, the calculation results of each step correspond to the calculation instructions one-to-one. When faced with real problems such as random phenomena and nonlinear coupling, deterministic computing often has problems such as low computational efficiency, complex algorithms, and consumption of a lot of hardware resources. Taking the Monte Carlo method as an example, it uses the asymptotic properties of random variables to obtain the expected value, which has wide applicability ...
