Abstract
A direct memory access (DMA) engine can be used to multicast data from system memory to a target memory for loading into an array. The DMA engine may include a controller that is configured to receive a data transfer request, and generate a set of write operations for the output interface. The set of write operations can include, for each of multiple partitions of the target memory, a write operation to write usable data from the multicast data to an address offset in the corresponding partition, and an additional write operation to write filler data from the multicast data to a null device address.
