Abstract
A processor includes an execution unit to generate a random number. The execution unit includes entropy source circuits, correlation circuits, and an extractor circuit. The entropy source circuits include all-digital components and are to generate an initial randomized bit stream. The correlation circuits are to remove correlations from the initial randomized bit stream to yield an intermediate randomized bit stream. The extractor circuit is to select a subset of the intermediate randomized bit stream as a random output of the execution unit.
