Amdahl’s law can be applied in contexts other than parallel processing. Suppose that a numerical application consists of 20% floating-point and 80% integer/control operations (these are based on operation counts rather than their execution times). The execution time of a floating-point operation is three times as long as other operations. We are considering a redesign of the floating-point unit in a microprocessor to make it faster. Question # 4: a) Formulate a more general version of Amdahl’s law in terms of selective speed-up of a portion of a computation rather than in terms of parallel processing. b) How much faster should the new floating-point unit be for 25% overall speed improvement? c) What is the maximum speed-up that we can hope to achieve by only modifying the floating-point unit? |
