There is one small mistake in diagram -> Step No 2 is DMAC request Disk Controller. Diagram mistake:- Step 2 look like CPU request Disk Controller.

Great explanation. But I'm kinda confused with the definition, which states that DMA removes the CPU from the process of data movement, but apparently the CPU still has to continually send the "DMA request" signal to the disk controller. This shows there's still a lot of CPU involvement; why can't the subsequent "DMA request" signals be sent by the DMAC instead? I think it would be great to see how things will happen without DMA, so as to better appreciate how much of the work is actually offloaded from the CPU to the DMAC.

@francescocarboni50 Жыл бұрын

Every type of I/O device has it's own controller. A controller "translates" I/O device signals to commands readeble by the OS. Every controller needs CPU to access needed data in the main memory. With the DMA mechanism, a device can directly access the main memory, without "asking" CPU. This mechanism is controlled by the DMA Controller and affects the interrupt signals system. Hope I helped :)
