What is an interrupt vector table. How do I create an interrupt
vector table in Arm Architecture . Please include as much
information as you can, including pictures, examples etc. Thank you
very much.
V. How does ARM processor differentiate between a timer
interrupt and an A/D interrupt?
VI. What does privileged mode mean and what is the major
difference between this mode and non-privileged mode?
VII. There are two interrupt pins on ARM microprocessor: IRQ and
FIQ. Which one can interrupt the other one and why?
How do I do the calculations for this chart (Table
#2)?

Problem 2. Interrupt-driven I/O (20 pt.)
Consider a system employing interrupt-driven I/O for a
particular device that transfers data at an average of 2000
bytes/sec on a continuous basis.
a. Assume that interrupt processing takes about 200 usec (i.e.,
the time to jump to the interrupt service routine (ISR), execute
it, and return to the main program). Determine what fraction of
processor time is consumed by this I/O device if it interrupts for
every byte.
b. Now assume that the...
