Which of the following address mode uses a buffer to hold data tempora

1.	Which of the following address mode uses a buffer to hold data temporarily?(a) 1D model(b) 2D model(c) dual address model(d) 3D modelI had been asked this question in homework.Question is from DMA-II in portion Basic Peripherals of Embedded Systems
Answer» The CORRECT choice is (c) dual address model The explanation is: The dual address mode supports two addresses and two accesses for transferring data between a PERIPHERAL or memory and another memory LOCATION, which also consumes two bus cycles and a buffer within the DMA CONTROLLER to HOLD data temporarily.
