MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Direct memory access (DMA) is the process of transferring data without the involvement of the processor itself. It is often used for transferring data to/from input/output devices. A separate DMA controller is required to handle the transfer. The controller notifies the DSP processor that it is ready for a transfer.

Detailed explanation-2: -Direct memory access (DMA) is a method that allows an input/output (I/O) device to send or receive data directly to or from the main memory, bypassing the CPU to speed up memory operations. Advertisements.

Detailed explanation-3: -Direct Memory Access (DMA) is a capability provided by some computer bus architectures that allows data to be sent directly from an attached device (such as a disk drive) to the memory on the computer’s motherboard.

Detailed explanation-4: -This set of Computer Organization and Architecture Multiple Choice Questions & Answers (MCQs) focuses on “Direct Memory Access”. Explanation: DMA is an approach of performing data transfers in bulk between memory and the external device without the intervention of the processor.

Detailed explanation-5: -Because the device is doing the work without the help of the CPU, this type of data transfer is known as direct memory access (DMA). DMA transfers can be performed between two devices, between a device and memory, or between memory and memory.
