Destructive DMA lists

A buffer, a method, and a computer program product for DMA transfers are provided that are designed to save memory space within a local memory of a processor. The buffer is a return buffer with a portion reserved for DMA lists. A DMA controller accomplishes DMA transfers by: reading address elements from a DMA list located in the DMA list portion; reading the corresponding data from system memory; and copying the corresponding data to the return buffer portion. This buffer saves space because when the buffer begins to fill up the corresponding return data can overwrite the data in the DMA list. Accordingly, the DMA list overlays on top of the return buffer, such that the return data can destruct the DMA list and the extra storage space for the DMA list is saved.
