Abstract
A memory of allocating memory for use by a subfunction of a computer chip, wherein the subfunction uses contiguous memory regions, the method comprising the steps of (a) creating a placeholder for contiguous memory buffers used by the subfunction of the chip by reserving a region of memory subsystem space, wherein the region does not need to be backed by true physical storage and the size is at least as large as the contiguous memory buffer required by the subfunction, (b) allocating pages of remaining memory in the memory subsystem to satisfy the amount of memory required by the subfunction, wherein the allocated pages do not necessarily result in a contiguous memory region, (c) remapping the allocated pages of step b into a contiguous region of the placeholder created in step a and (d) disabling the remapping after the subfunction is completed to free the memory in the placeholder.
