A Designer Wants to Improve the Overall Performance of a Given

question 11

Essay

A designer wants to improve the overall performance of a given machine with respect to a target benchmark suite and is considering an enhancement X that applies to 50% of the original dynamically-executed instructions, and speeds each of them up by a factor of 3. The designer's manager has some concerns about the complexity and the cost-effectiveness of X and suggests that the designer should consider an alternative enhancement Y. Enhancement Y, if applied only to some (as yet unknown) fraction of the original dynamically-executed instructions, would make them only 75% faster. Determine what percentage of all dynamically-executed instructions should be optimized using enhancement Y in order to achieve the same overall speedup as obtained using enhancement X.
