WebNov 19, 2024 · Which of the following DMA transfer modes and interrupt handling mechanisms will enable the highest I/O band-width? (A) Transparent DMA and Polling interrupts (B) Cycle-stealing and Vectored interrupts (C) Block transfer and Vectored interrupts (D) Block transfer and Polling interrupts Answer: (C) Explanation:
WebIf the bus is not being used by the CPU, it then steals the cycle, activates address lines, places blocks of bytes on bus data lines and releases the bus. The DMA repeats this cycle until the total bytes transferred equals the total requested. Finally, the DMA notifies the CPU of completion. What is a bus master?
