Abstract
A direct memory access controller comprises a plurality of registers defining parameters for multiple direct memory access transactions and transfer control circuitry responsive to data in the plurality of registers. The transfer control circuitry is adapted to automatically execute multiple, consecutive data transactions using the parameters of the plurality of registers. At least two consecutive data transactions are executed with respect to non-contiguous system locations.
