A METHOD OF AND SYSTEM FOR ASSESSING PROGRESS OF A TASK

摘要

Within the real-time processing domain, processing for example a video frame or audio can be divided into a number of tasks. Tasks receive budget (S102) for the resources it is allowed to use during processing. Since the processing performed by the tasks have timing constraints, a task must be able to determine its progress (S108). To enable a task to determine its progress the task refers to an amount of reference clock cycles it uses from a virtual reference clock and compares this amount to the number of sub-processing steps the task has performed. The virtual reference clock provides a plurality of reference clock cycles, wherein a reference clock cycle of the plurality of reference clock cycles is proportional to a ratio between the plurality of real-time clock cycles and the number of clock cycles comprised within the real-time budget.
