│ Real Random v1.2 │ by Chip Gracey │ (C)2007 Parallax, Inc. │ 23 March 2007 │
|
||||
├───────────────────────────────────────────┴────────────────┴────────────────────────┴───────────────┤
|
||||
│ │
|
||||
│ This object generates real random numbers by stimulating and tracking CTR PLL jitter. It requires │
|
||||
│ one cog and at least 20MHz. │
|
||||
│ │
|
||||
├─────────────────────────────────────────────────────────────────────────────────────────────────────┤
|
||||
│ Background and Detail: │
|
||||
│ │
|
||||
│ A real random number is impossible to generate within a closed digital system. This is because │
|
||||
│ there are no reliably-random states within such a system at power-up, and after power-up, it │
|
||||
│ behaves deterministically. Random values can only be 'earned' by measuring something outside of the │
|
||||
│ digital system. │
|
||||
│ │
|
||||
│ In your programming, you might have used 'var?' to generate a pseudo-random sequence, but found the │
|
||||
│ same pattern playing every time you ran your program. You might have then used 'cnt' to 'randomly' │
|
||||
│ seed the 'var'. As long as you kept downloading to RAM, you saw consistently 'random' results. At │
|
||||
│ some point, you probably downloaded to EEPROM to set your project free. But what happened nearly │
|
||||
│ every time you powered it up? You were probably dismayed to discover the same sequence playing each │
|
||||
│ time! The problem was that 'cnt' was always powering-up with the same initial value and you were │
|
||||
│ then sampling it at a constant offset. This can make you wonder, "Where's the end to this madness? │
|
||||
│ And will I ever find true randomness?". │
|
||||
│ │
|
||||
│ In order to have real random numbers, either some external random signal must be input, or some │
|
||||
│ analog system must be used to generate random noise which can be measured. We're in luck here, │
|
||||
│ because it turns out that the Propeller does have sufficiently-analog subsystems which can be │
|
||||
│ exploited for this purpose -- each cog's CTR PLLs. These can be exercised internally to good │
|
||||
│ effect, without any I/O activity. │
|
||||
│ │
|
||||
│ This object sets up a cog's CTRA PLL to run at the main clock's frequency. It then uses a pseudo- │
|
||||
│ random sequencer to modulate the PLL's target phase. The PLL responds by speeding up and slowing │
|
||||
│ down in a an endless effort to lock. This results in very unpredictable frequency jitter which is │
|
||||
│ fed back into the sequencer to keep the bit salad tossing. The final output is a truly-random │
|
||||
│ 32-bit unbiased value that is fully updated every ~100us, with new bits rotated in every ~3us. This │
|
||||
│ value can be sampled by your application whenever a random number is needed. │

||||
