Consider a DMA module that is transferring characters (as bytes), one at a time, to main memory from some I/O device connected directly to the DMA device. Suppose that I/O device transfers bit-by-bit at a rate of 4800 bits per second. Suppose the CPU can fetch 684000 instructions per second (with constant use of the system bus and main memory). How much will the processor be slowed down due to the DMA activity?
