Which of the following is used for supporting the priority scheme?(a)

1.	Which of the following is used for supporting the priority scheme?(a) address transfer mode(b) arbitration(c) counter(d) timerThis question was addressed to me in an interview for internship.Query is from Implementation of DMA in chapter Basic Peripherals of Embedded Systems
Answer» CORRECT ANSWER is (b) arbitration Explanation: The arbitration is used for providing priority to the DMA REQUESTS. The DMA request is simultaneously GENERATING, so in order to avoid the errors, a priority scheme is NECESSARY which is done by the arbitration scheme in the DMA controller.
