CPC G06F 12/10 (2013.01) | 12 Claims |
1. An electronic device, comprising:
a remapping hardware, converting a virtual address into a physical address;
a processor, executing software to configure the remapping hardware;
a Northbridge integrated circuit (IC); wherein
when the software changes the configuration of the remapping hardware, the remapping hardware outputs a first data draining request to the Northbridge IC;
when the Northbridge IC receives the first data draining request at a first time, the Northbridge IC suspends unconverted DMA requests received after the first time until a second time, and outputs a first data draining response to the remapping hardware at the second time; wherein the second time is later than the first time;
the remapping hardware receives the first data draining response and notifies the processor that the processing of the first data draining request has been completed.
