Abstract:
A memory system includes a memory including a page table, and an input/output memory management unit (I/O MMU) connected to the memory, and configured to receive a virtual address from an I/O Device and to search within the I/O MMU for a plurality of entries matching the virtual address. If no entries matching the virtual address are found within the I/O MMU as a result of searching for the entries, the I/O MMU accesses the memory, searches the page table for the entries matching the virtual address, and stores the entries within the I/O MMU.
