Developing a method which allow the predicting of the computing time of the developed algorithm, based on the specification in the higher level programming language is not yet satisfactorily solving challenge. This paper presents a new method for predicting the computing time of control algorithms implemented in a Simulink environment running on the target hardware. This method uses a refined benchmark database which achieves much better computing time prediction accuracy compared to other benchmark score-based methods used today. The benchmark score database can be created virtually for any target and no further information is required for this method to work. This makes the refined benchmark method very universal and portable compared to present virtual software benchmarks which require a very complex MCU description. This paper contains implementation details of the presented refined benchmark prediction method and demonstrates its accuracy on selected control algorithms (e.g. PID, state space controller).
