Intel 8259 interrupt controller-microprocessor, Assembly Language

Assignment Help:

Intel 8259 interrupt controller:

The 8088 processor has only two interrupt control inputs, and interrupt request (INTR) and non mask able interrupt (NMI). NMI are interrupts that can't be masked (for examples: power loss ,memory parity error). The interrupt controller has many functions:

It's receives interrupt requests from up to eight different sources.
It's prioritized and queues interrupts that come at the same time
it 's masks interrupt requests when instructed by the CPU
It's processes the CPU's interrupt-acknowledge signal by sending the interrupt vector number to the CPU.
