ABSTRACT:
A DMA controller has an attached, dedicated memory. Data objects are stored on the heap and connected by pointers. Each data object contains DMA block transfer control parameters. A single block transfer made up of several separate transfers, with each separate transfer defined by one data object. The single block transfer is defined by linking several data objects into a list. The DMA controller consecutively performs the transfers in a linked list without requiring control by a system central processor.
