What is the purpose of interrupts? How does an interrupt differ from a trap? Can traps be generated intentionally by a user program? If so, for what purpose?
Homework Answers
Answer)
An interrupt is the hardware generated change which means to flow in the system. The interrupt is a call to the CPU which informs the system about the hardware peripherals and devices. Normally, the CPU stays in a specific state and interrupt is used to change that state. Using an interrupt, the interrupt handler is called, control is then returned to the interrupted context and instruction. A trap is different than an interrupt as it is a software generated interrupt and can be cause by an error or request from the user program. Traps can be generated intentionally by the user program as they are software interrupts and can be used to be configured in the predictable places.

A given processor requires 1000 cycles to perform a context switch and start an interrupt handler (and the same number of cycles to switch back to the program that was running when the interrupt occurred), or 500 cycles to poll an I/O device. An I/O device attached to that processor makes 150 requests per second, each of which takes 10,000 cycles to resolve once the handler has been started. By default, the processor polls every 0.5 ms if it is...
