Method for determining the load of a computing device
First Claim
1. A method for determining the utilization of a computing apparatus, including a microcomputer having a real-time operating system, the method comprising the steps of:
- calling up an idle program when no other programs are any longer processed by the computing apparatus;
determining the number (ZMESS) of the call-ups of the idle program;
determining the total running time of the idle program;
evaluating one of the following;
(a) the number of call-ups of said idle program;
or, (b) the total duration of said idle program after a pregiven reference time span (TMAX) is exceeded; and
, after said reference time span (TMAX) is exceeded, referring the actual number (ZMESS) of call-ups to the actual measurement time duration (TMESS).

Abstract
A method for determining the utilization of a computing apparatus is described, especially for the determination of the utilization of a microcomputer having a real-time operating system. In the method, an idle program (2) is always then called up when no other programs are processed by the control apparatus. According to the invention, the number (ZMESS) of the call-ups of the idle program (2) or the total duration of the idle program (2) is determined. This number (ZMESS) is evaluated after a pregiven reference time span (TMAX) is exceeded. The number (ZMESS) of call-ups of the idle program (2) can be applied as a measure for the utilization of the computing apparatus.
