Direct Memory Access (DMA) The CPU can request data from an I/O controller one byte at a time, but doing so wastes the CPU's time.We assume that the CPU accesses all devices and memory via a single system bus that connects the CPU, the memory, ...

Transfer of control via Interrupts From the point of view of the user program, an interrupt is just that: an interruption of the normal sequence of execution. When the interrupt processing is completed, execution resumes. Thus, the user program does no...

Time Sequence of Multiple interrupts Time Sequence of Multiple interrupts As an example of this second approach, consider a system with three I/O devices: a printer, a disk, and a communications line, with increasing priorities of 2, 4, and 5, respective...
