Question

In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.

• A. Burst Signal
• B. Interrupt Signal
• C. Acknowledgement Signal
• D. Completion Signal

Hint:

DMA works independently of the processor for data transfer and uses an interrupt signal to notify the processor when the transfer is complete.

Answer 1

The Correct Option is B

In Direct Memory Access (DMA), after the transfer of data between peripherals and memory is completed, the processor needs to be notified so it can resume processing. This is typically done through an Interrupt signal, which halts the processor to notify it of the completion of the DMA transfer.
