Abstract
An electronic device includes remapping hardware, a processor, and a Northbridge IC. The remapping hardware converts a virtual address included in an unconverted DMA request into a physical address. The processor executes software to configure the remapping hardware. The Northbridge IC sends the physical address to the processor. When the software changes the configuration of the remapping hardware, the remapping hardware outputs a data draining request to the Northbridge IC. When the Northbridge IC receives the data draining request at a first time, the Northbridge IC suspends unconverted DMA requests after the first time until a second time, and outputs a first data draining response to the remapping hardware at the second time. The remapping hardware receives the first data draining response and notifies the processor that the data draining request has been completed.
