## Intro ## Intro
Random data generator. Random data generator.
Random data are obtained by reading the on-chip hardware random data generator seeded by an on-chip entropy source. Random data are obtained by reading the on-chip hardware random data generator seeded by an on-chip entropy source.
The data are accessed via the [rdrand instruction](https://software.intel.com/content/www/us/en/develop/blogs/find-out-about-intels-new-rdrand-instruction.html). Alternatively, pseudorandom data are generated by the permuted congruential generator (PCG) algorithm. The PCG code uses [minimal PCG implementation](https://www.pcg-random.org/download.html).
