ABSTRACT:
A method for retrieving information from a storage unit, the method includes: receiving, by an input output memory management unit second-level translation information representative of a partition of a storage unit address space; receiving, by a input output memory management unit, a direct memory access request that comprises a consumer identifier and a second memory address that was first-level translated by a communication circuit translation entity; performing, by the input output memory management unit, a second-level translation of the second memory address such as to provide a third memory address, in response to the identity of the consumer; and accessing the storage unit using the third memory address.
