Memory address space management method, memory address space management apparatus, and computer system

摘要

In a memory system having a plurality of block address translation entries each defining a portion of a memory address space, a method of managing a memory address space includes the steps of storing a received virtual address in one of the memory address spaces that are not defined by any block address translation entry Determining a portion of the memory address space that includes the received virtual address by reallocating the at least one block address translation entry; and using the reallocated block address translation entry to define a virtual And providing a physical address that matches the address. In a memory system having a plurality of block address translation entries each defining a portion of a memory address space, in a memory system having a plurality of block address translation entries defining a portion of the memory address space, The device reallocates at least one block address translation entry that determines that the received virtual address refers to a portion of the memory address space that is not defined by any block address translation entry, And a device for providing a physical address that matches the virtual address using the reallocated block address translation entry.
