Which of the following is used to calculate an offset to base address?

1.	Which of the following is used to calculate an offset to base address?(a) single address mode(b) dual address mode(c) 1D model(d) 2D modelI have been asked this question in an online interview.The origin of the question is DMA-II topic in section Basic Peripherals of Embedded Systems
Answer» The correct option is (d) 2D model For EXPLANATION I would say: An address stride is specified which can be used for CALCULATING the OFFSET to the base address at the terminal of count. This address stride is used in the 2D model of the DMA CONTROLLER.
