Abstract
A direct memory access (DMA) controller configured such that it attains a highest possible data transfer rate and short reaction time at a low microprogram length, and short read times on transfer demands. This is attained by providing, in addition to a microprogram interim memory, a data handling unit, wherein the microprogram interim memory receives the microinstruction for the presently working channel from a microprogram memory via one of the channel-specific instruction registers, for which there is provided one instruction register for each channel. The data handling unit, after being initialized by the microprogram, independently controls the channel-specific processing of the transfer of DMA information.
