A base address sorting device in a switching device is disclosed that includes an array of base address registers in which each base address register contains a base address, an address shifting device; and a control logic element electrically coupled to the array of base address registers and operable, upon receiving a configuration command comprising a new base address, to implement a method for reconfiguring the contents of the array of base address registers. The method includes determining an insertion point base address register in the array of base address registers into which to write the new base address, shifting the contents of one or more base address registers array to other base address registers to preserve the sorted order, and shifting the contents of the configuration command into the insertion point base address register. The inserting results in preserving the pre-determined order of the register array content.
