Patent ID: 8131789

Claim:
A circuitry for generating random data comprising: a first oscillator having an output frequency that is selectable through a select input of this first oscillator; a first means for dynamically varying the output frequency of the first oscillator coupled to and providing output signals to the select input of the first oscillator; a second oscillator; a first circuitry coupled to an output of the first oscillator, the first circuitry providing a multi-bit value capable of being modified at each clock cycle generated by the output of the first oscillator; a second circuitry coupled to an output of the second oscillator, the second circuitry providing a multi-bit value capable of being modified at each clock cycle generated by the output of the second oscillator; and a combinational circuitry combining the multi-bit value provided by the first circuitry and the multi-bit value provided by the second circuitry in order to generate a multi-bit random number.
