Abstract
PURPOSE:To simplify a random number generating circuit, by leading out plural optinal outputs in halfway stages of a frequency divider simultaneously to use these led-out outputs as random numbers. CONSTITUTION:Each stage of a frequency divider 1 consists of an FF circuit, etc., and the signal of a prescribed frequency phi is applied from a quartz oscillator or the like and is divided successively, and plural outputs of prescribed different frequencies f12-f15 are taken out from halfway stages of the frequency division and are applied to an accumulator 2. The random number command instruction is given to the accumulator 2 from an arithmetic device 3 of a microcomputer or the like, and outputs of frequencies f12-f15 of the frequency divider 1 are stored as random numbers in the accumulator 2 at a prescribed timing synchronized with this command instruction, and contents of the accumulator 2 are given to the arithmetic device 3 as random numbers as required. Thus, the constitution of the random number generating circuit is simplified.
