METHOD AND ARRANGEMENT FOR MEASURING THE RUNNING TIME OF FUNCTIONS

摘要

Measurements of the running time of functions of a computer program (2) are an instrument for improving the computer program (2) to the effect that the resources of a computer system (1) can be used in an optimum manner. Measurement of the running time of one or several predefinable functions has to be carried out in a quick and reproducible manner according to given operational conditions of the computer system (1). A measurement manager function (3) is used as a component of the computer program (2). During the execution of the computer program (2), said measurement manager function inquires whether a predefinable function or one of the given functions is involved when a function is called up. If this is the case, time information is stored by means of a time stamp function (4) at the beginning and end of the execution of said function. Interruptions in the execution of the function are recognized and are taken into account during measurement of running time. The invention is particularly suitable for use in the development of computer programs for operating realtime sytems for controlling engines in automotive technology.
