Abstract: The invention is based on the idea to separate a synchronisation operation from reading and writing operations. Therefore, a method for data processing in the data processing system is provided, wherein said data processing system comprises a first and at least a second processor for processing streams of data objects, wherein said first processor passes data objects from a stream of data objects to the second processor. Said data processing system further comprises at least one memory for storing and retrieving data objects, wherein a shared access of said first and second processors is provided. The processors perform a read operations and/or write operations in order to exchange data objects with his said memory. Said processors further perform inquiry operations and/or commit operations in order to synchronise a data object transfer between tasks which are executed by said processors.

Abstract: A data processing system is claimed which comprises a plurality of processors (12a, 12b, 12c) which communicate data streams with each other via a shared memory (10). The data processing system comprises processor synchronization means (18), for synchronizing the processors (12a-c) when passing the stream of data objects. For that purpose the processors are capable of issuing synchronization commands (Ca-c) to the synchronization means (18). At least one of the processors (12a) comprises a cache memory (184a), and the synchronization means (18) initiate a cache operation (CCa) in response to a synchronization commands (Ca).
