Suppose 2 processes pi and p are attempting to use a machine with interrupt-driven I/O concurrently. Assume each process needs CPU first, and then I/O device.
p: tcPU=10, tio=70 p: tcPU=30, tio=20
Assume that no two processes can use the I/O device/CPU at the same time. What is the minimum amount of time required to execute the 2 processes? Please also give the schedule chart.
p1:
p2:
I/O:
The minimum total time is:
