<p>In a data processing pipeline system comprising: - a cascade of data processing modules for the processing of successive groups of data units which are relevant to the processing and which are presented to the system input, said groups being separated from one another by time slots, - control means for supplying the modules with at least one control signal for controlling the processing by the modules, which control signal occurs in synchronism with the presence of each group on the system input, a loss of information occurs due to processing delays if data transport between the modules takes place in a time slot because of the absence of control signals. Therefore, the pipeline system comprises: - monitoring means for stopping the processing by the modules in a time slot on the system input in the absence of the control signal. When the control signal (for example, sampling signals) are of a periodic nature within each processing cycle, indicated by a data valid signal, a length (expressed in data units) of each cycle equals an integer multiple of a length of a period of each control signal. In that case the control signals do not comprise a phase jump between successive cycles, so that further loss of information is avoided.</p> |
