WebInterrupts & externally initiated signals. Interrupts are the signals generated by external devices to request the microprocessor to perform a task. There are 5 interrupt signals, i.e. TRAP, RST 7.5, RST 6.5, RST 5.5, and INTR. We will discuss interrupts in detail in interrupts section. INTA − It is an interrupt acknowledgment signal. WebJun 29, 2024 · What is the basic advantage of using interrupt initiated data transfer over transfer under program control without an interrupt? The main advantage is reduced latency. The processor has to temporarily halt it’s work in programmed I/O, whereas in interrupt I/O, the processor continues to perform and only halts when interrupt is received.

WebA priority interrupt is a system which decides the priority at which various devices, which generates the interrupt signal at the same time, will be serviced by the CPU.

WebNov 21, 2012 · Interrupts may be initiated by the CPU (exceptions - e.g.: divide by zero, page fault), devices (hardware interrupts - e.g: input available), or by a CPU instruction (traps - e.g: syscalls, breakpoints). They are eventually managed by the CPU, which "interrupts" the current task, and invokes an OS-kernel provided ISR/interrupt handler.
