Single dma transfers from device drivers to network adapters.Methods and arrangements of data communications are discussed. Embodiments include transformations, code, state machines or other logic to provide data communications. An embodiment may involve receiving from a protocol stack a request for a ...
When the data bus is cut off from the CPU () and the transmission ready signal (TXRDY) is activated, the DMA control circuit () reads bits of data at once according to the lead address of the destined area for storage in the DRAM () and the address width that are set by the CPU...
detected. A transfer request can be triggered from software, from an external trigger source (peripheral) or from an event. There are dedicated source trigger selections for each DMA channel. The available trigger sources may vary from one device to anoth 当DMA调动请求被查出时, DMA调动可能只...
