ABSTRACT:
Distributed digital signal processing is executed by a number of processing elements. Signal processing processes are scheduled for individual processing elements according to the data flow principle. To this end, the flow of signal samples is subdivided into data tokens, each of which has several samples. A process is started in a processing element in response to the detection of a data token presented so as to undergo the process. The detection is processed by a control unit which, in response thereto, allocates a communication connection between a first processing element producing the relevant data token and a second processing element which is to process the data items present in the data token. Scheduling is thus achieved by allocation of the communication connection. Furthermore, in order to avoid deadlock problems, restrictions are imposed as regards the execution sequence of processes.
