VIAのCPUの乱数発生装置
秋葉専攻の某先輩から教えてもらった．こんなのがついてるんですね．
... The VIA PadLock RNG uses random electrical noise on the processor chip to generate highly random values at an extremely fast rate. ...
Capable of creating random numbers at rates of between 800K to 1600K bits per second, ...
The RNG hardware comprises two parts: a raw-bit generator that serves as an entropy source and digital post-processing circuitry. ...
Raw bits are generated by using a slow freewheeling oscillator (configured by bias inputs to 20-68 MHz) to clock the sampling of a fast freewheeling oscillator (configured by bias inputs to 450-810 MHz). ...
