1. In a processing system, a real time usage indicator comprising:
- means for setting being operated in response to said processor system to set each of a plurality of status bits of a status display data word representing internal processor system events;
display means for indicating being operated in response to said processor system and said means for setting to transmit said status display data word including said plurality of status bits;
means for storing connected to said processing system and being operated to store said status display data word including a value of one of said status bits being a trigger signal;
means for timing connected between said display means and means for storing, said means for timing being operated in response to the duration of said trigger signal to produce a first output signal, a second output signal or a third output signal, corresponding to first, second and third time durations in excess of first predefined time period;
said display means being operated in response to said first output signal, said second output signal and said third output signal to provide visual indication of the occurrence of said first, second and third output signals for a predefined duration of time;
means for resetting being operated in response to said processor system to reset each of said plurality of status bits of said status display data word; and
said display means being further operated in response to said means for resetting to provide visual indication of a non-occurrence of said first, said second and said third output signals.

Abstract
This invention is a device which permits the percentage of real time consumed by software tasks of a telecommunications switching system or other process controller to be measured and displayed on a percentage meter. The relative percentages of different real time tasks are displayed by the relative intensities of particular lamps mounted on a control panel of a meter. Non-standard, user defined, software tasks may be selected for display on the meter. Software tasks which over-shoot a predetermined amount of time provide an indication of this by lighting one of a number of different lamps. Each of these lamps measures a predetermined amount of over-shoot time.
