ABSTRACT:
A measurement mechanism which can be implemented in any complex system for measuring the service times required for carrying out specified operations is described for a system having a plurality of components working in pre-emptive mode so that an operation once started by a component can be suspended to perform other operations which are requested by the same or other components if these operations have higher priority levels. The measurement mechanism includes a current status register 16 in which the system causes a status value to be stored representative of the current operation being performed by the system. It also includes a reference status register 18 in which a reference value representative of the operation to be measured is stored. These values are compared through a compare logic circuit under control of a filtering value stored in another register. When a match is detected by the compare circuit, the content of a counter is incremented. At the end of the measure, the content of the counter is transferred into another register, the content of which represents the measured value. By selecting the filtering value any specified partial or total service time can be directly measured.
