Abstract
A direct memory access controller includes a source memory controller for controlling a source memory, a destination bus controller for controlling the transfer of data to a destination memory, a first-in-first-out memory buffer for receiving data from the source memory, and a filter connected upstream of the first-in-first-out memory buffer for comparing the source memory data to a filter criterion and passing to the first-in-first-out memory buffer only that data which matches the filter criterion.
