Abstract
Address translation for a source and destination of the data that utilizes different page tables. A direct memory access (DMA) engine is used as a memory-to-memory copy engine by utilizing a page-table walk and address translation for a source side of the copy, and an independent page-table walk and address translation for a destination side of the copy.
