    Patent number: 9645934
    Abstract: A page descriptor can be stored in advance in a memory management unit under various conditions so that an address translation overhead can be reduced. The memory management unit comprises an address translation unit that receives a memory access request as a virtual address and translates the virtual address to a physical address. A translation lookaside buffer (TLB) stores page descriptors of a plurality of physical addresses, the address translation unit determining whether a page descriptor corresponding to a received virtual address is present in the translation lookaside buffer. A prefetch buffer stores page descriptors of the plurality of physical addresses.
