Abstract:
A method or system of translating a virtualized address to a real address is disclosed that includes receiving a virtualized address for translation; generating a predicted intermediate address translation using a portion of the bit field of the virtualized address; determining a predicted real address using the predicted intermediate address or portion thereof; performing a translation of the virtualized address to an actual intermediate address; determining whether the predicted intermediate address is the same as the actual intermediate address; and in response to the predicted intermediate address being the same as the actual intermediate address, providing the predicted real address as the real address.
