ABSTRACT:
Machine-readable media, methods, and apparatus are described for performing direct memory access (DMA) transfers. In some embodiments, a device may generate an interrupt to request a DMA transfer. A DMA controller may claim the interrupt and may prevent a processor from receiving and/or servicing the claimed interrupt. The DMA controller may further transfer a data block in response to the claimed interrupt.
