PROBLEM TO BE SOLVED: To provide an estimating device for estimating software execution times. SOLUTION: A method for statistically estimating software execution times is implemented by preparing a model of a target processor based on a set of benchmark programs, correlating the software to be estimated to the benchmark programs, applying the correlated software to the model and determining the estimated values of software execution times. The model is developed by determining the actual execution times of the benchmark programs, determining a number of virtual instructions in the benchmark programs and determining a predictor equation that correlates the virtual instructions to the actual execution times. The predictor equation is determined by making a correlation analysis of the virtual instructions, excluding highly correlated instructions, and executing a combination of stepwise linear regression and multiple linear regression.
