How is data transfer done in interrupt and DMA mode?
Data transfer to and from the peripherals may be done in any of the three possible ways Interrupt- initiated I/O. Direct memory access ( DMA). Now let’s discuss each mode one by one. Programmed I/O: It is due to the result of the I/O instructions that are written in the computer program.
Why do we use DMA instead of Port I / O?
As an alternative to Port I/O, Direct Memory Access (DMA) Input/Output permits specialized external IO processors to perform IO operations between I/O devices and memory which is shared with the main processor. – One way to increase the speed at which a process is performed is to increase the number of processors working on the problem.
How does the DMA controller work with the CPU?
It sends a DMA request (in form of interrupt) to CPU. CPU initiates the the transfer by providing appropriate grant signals to the data bus. And passes the control to the DMA controller which controls the rest of the data transfer and transfers the data directly to I/O device.
