Of the peripherals listed in the table, which would benefit from DMA? What criteria determine if DMA is appropriate?

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
