Initially, an interrupt associated with an interrupt service routine is received during processing of the instruction set. In response to receipt of the interrupt, an interrupt instruction register is accessed containing at least one interrupt instruction associated with the interrupt service routine. The...
The ISR returns a logical interrupt, in the form of an interrupt identifier, to the interrupt handler and typically masks the board-level device interrupt. The interrupt handler re-enables all interrupts at the microprocessor, with the exception of the current interrupt, which is left masked at ...
Note that other processors can still handle interrupts, though you will never see two processors handling the same IRQ at the same time. To summarize the slow and fast executing environments: A fast handler runs with interrupt reporting disabled in the microprocessor, and the interrupt being ...

Peng Zhang, in Advanced Industrial Control Technology, 2010 (b) Interrupt handler Interrupt handling is a key function in real-time software, and comprises interrupts and their handlers. Only those physical interrupts which of high enough priority can be centered into system interrupt table. The sof...

When an interrupt occurs, the microprocessor transfers control to an exception handler in the kernel. The exception handler then calls the ISR registered to handle the current interrupt. The ISR is responsible for translating the interrupt into a logical interrupt identifier, a SYSINTR, which it ...
