Abstract
A method for remapping a virtual address to a physical address is provided. The method is used in an address remapping unit and includes: receiving, by a remapping processing unit of the address remapping unit, a remapping request, decoding the remapping request and determining whether the remapping request has a direct memory access (DMA) remapping request; and executing, by the remapping processing unit, a remapping procedure: translating a virtual address corresponding to the remapping request to a physical address, when the remapping request has the DMA remapping request.
