Solving Pipeline Questions Methods and Equations

While solving pipeline questions remember the following...

1) Given Stage delays and overhead

       Clock time = Max(Stage delay)+ Overhead

2)Number of instructions(n) and number of stages(k) are given

Number of Clocks =( k+ (n-1)   ) clocks

3) Percentage of brach instuctions and number of stalls  are given

   Time taken= 1+stall * number of stalls

4)Frequency = 1/Time period

5) Don't forget about  hazards and dependencies and operand forwarding techniques while solving pipeline questions

6) Efficiency of pipeline = speed up/ number of stages

7)In ideal condition Maximum speed up =number of stages

8)Remember Speed up is always greater than 1

9)Throughput = 1/Time

10) Highest stage delay then lowest clock frequency

11) Total Execution time= Number of instructions * CPI(Clocks per instructions) * cycle time

Sometimes our system shutdown immediately after working for sometime and this may happen frequently.

Normally we will think this is because of hardware error or something like that. But remember that hardware error causes some sound from inside the system. Mainly this immediate shutdown is because of software errors due to missing of some files. This missing arise mainly  due to improper shutdown.. For fixing such errors boot from windows cd or usb and go for REPAIR windows option.
