Explain the Memory stack organization of 16 locations of stack( 0 to 15). take the initial value of the

stack pointer is SP = 0E in Hex. Explain the following push and pop instructions through the Memory

stack organization diagram.

(1) PUSH R5 WHERE R5 = XX in Hex

(2) POP R4 WHERE R4 = (XX + 3 ) Hex for example roll no 64 is having the data in R5 = 64

Hex and R4 is ( 64+3 = 67 Hex) [5 marks]

In a certain computer system, five (5) processes A, B, C, D, and E are active with their burst times (in ms) of 8, 10, 2, 4, and 3 respectively. These processes come at times (in ms.) 16, 0, 4, 20, and 29 respectively and use FCFS to schedule the execution. 

Required information:

1. Draw the Gantt chart showing the execution of the CPU.
2. What is the CPU utilization?
3. What is the system’s throughput (in process /ms)?
4. What is the average turnaround time of all the processes?
5. What is the average waiting time of all the processes?
