Abstract:

A hardware-based digital random number generator is provided. The digital random number generator is a randomly behaving random number generator based on a set of nondeterministic behaviors. The nondeterministic behaviors include temporal asynchrony between subunits, entropy source “extra” bits, entropy measurement, autonomous deterministic random bit generator reseeding and consumption from a shared resource.

Abstract:

A processor and method for translating a nonphysical address into a physical address are disclosed. A determination is made if a first entry set which could contain a particular entry that associates a selected nonphysical address with a corresponding physical address assigned to a device in the data processing system is stored within a first memory of the data processing system. In response to a determination that the first entry set is not stored in the first memory, a determination is made if a second entry set which could contain the particular entry is stored within the first memory. In response to a determination that the second entry set is stored in the first memory, a search of the second entry set is initiated in order to locate the particular entry. In response to locating the particular entry, the selected nonphysical address is translated to the corresponding physical address utilizing the particular entry. In one embodiment, if the first entry set becomes available during the search of the second entry set, the first entry set is preferentially searched prior to completing the search of the second entry set.
