Random Number Generator

24.1

Theory of Operation

The Random Number Generator (RNG) unit provides a digital, random-number-
generation capability.
The Random Number Generator (RNG) produces a series of random numbers for use in,
among other things, key generation. The only method of access to these numbers is via
a read from the random number FIFO. No other visibility is provided into the workings
of this unit by the processor, nor is their any method of control or parameterization by
any external method.
