A circuit is described that forms part of a microprocessor-based communications switching system performing similar functions to that described by Wittie 1. On paper, the designed system has a throughput of 10 000–20 000 character/s per processor, and has the capability of handling large ...
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 ...
void (*handler)(int, void *, struct pt_regs *) The pointer to the handling function being installed. We'll discuss the argu- ments to this function later in this chapter. unsigned long flags As you might expect, a bit mask of options (described later) related to inter- rupt management...
The microprocessor will then set the controller to point to the correct entry in the vector table and execute that instruction. This instruction will alter the controller to point to the interrupt handler. Once in the interrupt code, the interrupt handler has to first save the context, so that...

In summary, the interrupt vector table is an array of function pointers that points to the starting address of exception or interrupt handlers of a microcontroller or microprocessor. IVT usually stores at the starting addresses of flash or code memory. ...
