a) Consider Daisy Chain Priority Interrupt Scheme. First, draw the corresponding hardware block diagram when there are 8 I/O devices. Assuming that 1/O devices 2 and 4 want to interrupt the processor, explain how interrupt requests are handled. (7.5 points) c) Now consider Parallel Interrupt Priority Scheme. Draw the corresponding hardware block diagram and explain how I/O devices 2 and 4 interrupt requests are handled. (7.5 points)
