Decrease the clock time or Increase clock rate by reducing propagation delays or by use pipelining.

Decrease the CPI (clock cycles per instruction) by using new Hardware.= Instruction Count x CPI x clock cycle time of instructions / Program ) x (Clock cycles / Instruction) The number of CPU clock cycles can be determined by, CPU clock cycles Since clock cycle time and clock rate are reciprocals, so, Execution time = CPU clock cycles / clock rate That means machine A is 1.25 times faster than Machine B.ДЄnd, the time to execute a given program can be computed as: Execution time = CPU clock cycles x clock cycle time Machine A runs a program in 100 seconds, Machine B runs the same program in 125 seconds (Performance of A / Performance of B) Performance is determined by execution time as performance is inversely proportional to execution time. This is also referred to as simply CPU time. It also excludes time for I/O or running other programs. Therefore, performance of A is greater than that of performance of B. CPU execution time is the total time a CPU spends computing on a given task. If given that Processor A is faster than processor B, that means execution time of A is less than that of execution time of B.
