PROBLEM TO BE SOLVED: To manage a single memory pool provided with a frame buffer memory and a display list memory. SOLUTION: The single memory pool can comprise sub-pools including a super-block pool comprising a plurality of super-block objects, a node pool comprising a plurality of node objects, and a block pool comprising a plurality of blocks. This method allocates an object local to the sub-pool identified in a memory request side, if local sub-pool objects are avilable to satisfy the memory request, allocates an object from the super-block pool, if the memory request is directed to the node-pool or block-pool and there are no available local objects in the respective sub-pools to satisfy the memory request, and applies at least one of a plurality of memory freeing strategies, if the sub-pools lack available free objects.
