Q 1. Suppose we have a 1.5-GHz CPU to which the following three I/O devices are connected:
Polling requires 300 instructions for each I/O device. Students are required to compute the percentage of CPU time required to poll each device.
Q 2. Instead of polling, we want to use interrupts for handling the DVD drive. Keeping in view the DVD drive to be active only 12% of the time, you are required to compute the percentage of CPU time for handling it.
Note: Interrupt and polling requires the same amount of instructions.

plz solution share kar dy cs501 ka
how to calculate % of CPU? any idea
50*300 = 15000
15000/(10*10^6) = 0.0015%
Bhai aap ny MIPS kasy calculate keye hen? Ya phir sirf assume kr rhy hen k MIPS 10 hen?
plz solution send kery cs501 3rd asighnmnt on my id email@example.com
10^9 use hogi because processor GHz ka hai
I have doubt on DVD calculation because of the 16byte chunks in book it is divided by 2 then calculated other wise same answers 10.24
Lkn is me ek doubt he, apny MIPS 1500 use keye hen na? MIPS aur processor speed me farq hota he.
Me to 2 bar email kr k instructor se poch chuka hoon k CPI to given nhi he to MIPS kis trha calculate kren, ek bar unho ny kaha k internet pe search kr lo aur dosri bar kaha k kal VVH session me appear ho.
g mujhy bi google or recomended books ki rah dikhae
