Difference between TDD and FDD For example, there are 12 instructions and they are executed in 4 seconds. To get better CPI values without pipelining, the number of execution units must be greater than the number of stages. For example, if a computer has four processors and it takes 5 seconds to execute a task, then the number of MIPS is (5/4) = 1.25 (or 25%). Assume sequentially executing CPU. The Number of clock cycles required to execute each instruction, CPI = The number of clock cycles required to execute the program / number of instructions executed in running the program. , Execution time = Instruction Count x CPI x clock cycle time = Instruction Count x CPI / clock rate The units for CPU Execution time are: How to Improve Performance? 2 xref = of instructions and Execution time is given.
