Question: Does the CPU relinquish control of memory when DMA is active? For example, can a peripheral simply communicate with memory directly, avoiding the CPU completely?

Does the CPU relinquish control of memory when DMA is active? For example, can a peripheral simply communicate with memory directly, avoiding the CPU completely?

Direct Memory Access (DMA) allows devices to access memory directly rather than working through the CPU. This can dramatically speed up the performance of peripherals, but adds complexity to memory system implementations. Explore DMA implications by answering the questions about the following peripherals. a. Mouse Controller b. Ethernet Controller
