What is the equation for pipelining?
, time = (1st total set) + (total steps - 1) * (slowest step)
The manufacturing process for producing a widget has 5 steps and each step in
the process takes one day.
What is the average number of days needed to manufacture each widget using a
pipelined process to produce 10 widgets?
1.4 days
What is the equation for non-pipelining?
time = (number of steps) * (number of sets)
An instruction set has 8 steps and each step takes one clock cycle.
What is the number of cycles needed to complete each instruction set using a
non-pipelined process to complete 100 instruction sets?
800 cycles
What is the equation for performance improvement?
speed = (old speed / new speed) - 1
An instruction set has 8 steps and each step takes one clock cycle.
What is performance improvement using a pipelined instead of a non-pipelined
process to complete 100 instruction sets?
7.477 - 1 = 6.477%
An instruction set has 8 steps and each step takes three clock cycle.
What is the number of cycles needed to complete each instruction set using a
non-pipelined process to complete 100 instruction sets?
2400 cycles
When a question asks "How many seconds is the CPU performance for the task"
in addition to containing the phrases "clock rate", "instructions", and "CPI" which
CPU equation should be used?
time = (instructions * CPI) / (rate)
A program with 5000e9 instructions runs alone on a CPU. The CPU clock rate is
3e9 cycles per second, i.e. 3GHz. The average cycles per instruction is 3. How
many seconds is the CPU performance for this task?
5000 seconds
When a question asks "How many seconds is the CPU performance for the task"
in addition to containing the phrase "clock cycle time", "CPI", and "instructions"
which CPU equation should be used?
time = (CPI x clock time x CPI)
A program with 5000e9 instructions runs alone on a CPU. The CPU clock cycle
time is 3.33e-10 per second. The average cycles per instruction is 3. How many
seconds is the CPU performance for this task?
5000 seconds
How do you input a repeated decimal on a TI-84 calculator? i.e. 3.33e-10
Enter the repeated decimal at least 11 times. 3.3333333333e-10
