  • Network controller for switching into DMA mode based on anticipated memory overflow and out of DMA mode when the host processor is available
    Patent number: 5878217
    Abstract: A network controller has a default non-DMA mode of data transfer that transfers received data frames to a desired location in internal memory under control of a host CPU. A DMA mode of data transfer is engaged to transfer accumulated data frames via a DMA controller to system memory when the host CPU is not available to handle the frame processing. An automatic switch back mechanism is provided to allow the network controller to automatically switch back to the non-DMA data transfer mode as soon as the host CPU is able to return to processing of received frames.
