Without a process such as DMA, the computer's CPU becomes preoccupied with data requests from an attached device and is unable to perform other operations during that time. With DMA, a CPU initiates a data transfer with an attached device and can still perform other operations while the data ...
The device will usually interrupt when the DMA transfer is complete. The device takes a single physical address base & a length for each fragment of an operation. It interrupts when it's done transferring each fragment, allowing your driver to program in the next one. This is going to be ...

controller to access to the system bus, the DMA controller will transfer all bytes of data in the data block before releasing control of the system buses back to the CPU, but it will cause the CPU to be inactive for a considerable long time. This mode is also called “Block Transfer ...
Someexpansion boards, such asCD-ROMcards, are capable of accessing the computer’s DMA channel. When you install theboard, you must specify which DMA channel is to be used, which sometimes involves setting ajumperorDIP switch. Was this Article helpful?YesNo ...
