Abstract: Systems and techniques are provided for random number generation. For instance, a process can include generating, using a first random number generator of a plurality of random number generators, a first random number; inputting the first random number to a first flow engine of a plurality of flow engines, wherein the first flow engine is coupled to a random number consumer, of one or more random number consumers, through a first set of flow engines, of the plurality of flow engines, wherein the plurality of flow engines are unclocked; randomly transforming, by the first set of flow engines, the first random number to a second random number; and buffering the second random number from the first set of flow engines for output to the random number consumer.
