  • Method and apparatus for allocating storage addresses
    Patent number: 8281103
    Abstract: A method and apparatus for allocating storage addresses are disclosed. The method includes: receiving a storage address allocation request; searching a level-2 bitmap in a hierarchical bitmap in bidirectional mode; outputting an idle bit according to the result of searching in the level-2 bitmap; obtaining a storage address according to the output idle bit, and allocating the storage address. The apparatus includes: a first receiving module, configured to receive a storage address allocation request; a first searching module, configured to search a level-2 bitmap in a hierarchical bitmap in bidirectional mode for an idle bit, wherein the hierarchical bitmap includes N level-1 bitmaps and the level-2 bitmap; and an allocating module, configured to: obtain a storage address according to the output idle bit in the level-2 bitmap, and allocate the obtained storage address.
