Abstract
A method for accessing a physical region page (PRP) list includes obtaining a PRP address of a PRP list, in which the PRP address has M bits; performing operation to the first N bits of the PRP address and the N+1 th to Mth bits of the PRP address respectively to obtain a page base address if the PRP address is within a page boundary; and performing operation to the first N bits of the PRP address and the N+1 th to Mth bits of the PRP address respectively to obtain next PRP address pointer if the PRP address reaches the page boundary. N is an integer, and M is an integer larger than N.
