Abstract
A reordering command queue for reordering memory accesses in a computer system. The reordering command queue may reduce the power that is typically used up in computer systems when performing accesses to main memory by improving the scheduling of memory accesses with a pattern that is optimized for power and which has no (or negligible) impacting on performance. During a compare operation, the address corresponding to the command stored in each of one or more current storage locations of the reordering command queue may be compared to the address corresponding to the command stored in an adjacent storage location to determine whether the commands are in a desired order. In response to one or more of the commands not being in the desired order, a reordering operation may be performed, which may reorder each of the one or more commands from a current storage location to the adjacent storage location.
