Abstract

PURPOSE:To shorten a processing time and also to lighten the burden of software, by realizing the generation of random numbers by hardware logic. CONSTITUTION:A numerical value is set in advance in a counter 1, it is counted up by a prescribed number, and a counter output 1a is obtained. When the output 1a is multiplied by a constant in a digital multiplier 2, and a multiplication output 2a is obtained. It is set to a register 3, in which optional continuous bits are fetched and made random numbers 3a. They are preset to the counter 1 again, and the next random numbers are obtained by the same procedure. By generation of these random numbers, it becomes possible to fetch and process the random numbers 3a at an optional time by executing at a higher speed than a processing period for which the random numbers are required. According to this constitution, the random numbers are generated by hardware logic, the processing is executed at a high speed, and the burden of software is lightened.
