ABSTRACT:
A direct memory access device has an increment counter for indicating an address increment between succeeding transfer blocks of data from a first storage location to a second storage location within a memory device. Each block of data has a lateral width determined by the content of a line byte counter associated with both the source and destination areas of the memory device. After the transfer of each block of data, the address is advanced by an amount corresponding to the content of the increment counter. The direct memory access device is capable of multi-dimensional data transfers; for example, two- and three-dimensional transfers.
