Abstract
PURPOSE:To improve the use efficiency of a memory and to perform quick garbage compaction by inverting a pointer in case of necessity and removing a block, which has no sequentially used areas at all, from a list in case of movement and moving and restoring areas in the other blocks. CONSTITUTION:A sequentially used area successively linked to a table base pointer 5 is taken out and point directions of this area and the following sequentially used area are inverted in case of necessity and an inversion flag is stored in the following sequentially used area by an inversion processing part 1, and this area is moved to an idle area of the preceding block or the pertinent block by an idle area move and restore processing part 2 and point directions are returned, and the block which has no sequentially used areas at all is removed from the list in case of this movement by a block elimination processing part 2-1. Thus, sequentially used areas scattered in discontinuous areas are moved forward to efficiently and satisfactorily gather unused areas, and unnecessary movement is eliminated to quickly perform garbage compaction.
