What is interrupt and its types in computer architecture?
An interrupt is a control signal sent to the microprocessor to draw its attention. It is a type of signal to processor in which processor,on receiving the interrupt request,stops its current operation and starts executing the subroutine associated with the interrupt signal.
What is interrupt and its types in microprocessor?
Interrupts are the signals generated by the 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. Vector interrupt − In this type of interrupt, the interrupt address is known to the processor. For example: RST7.
What is mean by interrupt?
Interrupt. An interrupt is a signal sent to the processor that interrupts the current process. It may be generated by a hardware device or a software program. A hardware interrupt is often created by an input device such as a mouse or keyboard.
What are hardware and software interrupts?
Hardware interrupt is an interrupt generated from an external device or hardware. Software interrupt is the interrupt that is generated by any internal system of the computer (instruction in the program). Type Of The process.
What happens when interrupt occurs?
When an interrupt occurs, it causes the CPU to stop executing the current program. When an interrupt is generated, the processor saves its execution state via a context switch, and begins executing the interrupt handler at the interrupt vector.
What is the purpose of interrupts?
Role of Interrupts. Interrupts are signals sent to the CPU by external devices, normally I/O devices. They tell the CPU to stop its current activities and execute the appropriate part of the operating system. Hardware Interupts are generated by hardware devices to signal that they need some attention from the OS.
