A method, system and computer program product for optimizing EPN to RPN
translation when a data miss occurs. The method, system and computer
program product take advantage of the high-likelihood of finding the
matching PTE in the first half of the PTEG and utilize early data-coming
signals from the L2 cache to prime the data-flow pipe to the D-ERAT
arrays and requesting a joint steal cycle for executing the write into
the D-ERAT and a restart request for re-dispatching the next-to-complete
instruction.
