摘要:
A random number generator, a method, and a computer program product are provided for producing a random number seed. Each oscillator within an array of oscillators operates at a different frequency. The operating frequencies of each oscillator are not harmonically related, such that no integer multiple exists between the frequencies of any two oscillators. In one embodiment, the outputs of the array of oscillators connect to a multiple input latch. The multiple input latch also receives a sample signal, which is a clock signal. The clock signal samples the outputs of the array of oscillators, and the multiple input latch in conjunction with the random number determination logic (“RNDL”) produces a digital output (0 or 1) for each oscillator within the array. The RNDL uses these digital outputs to create a random number seed.
