PURPOSE:To improve the processing performance by executing respective processings of producers, a merger process, and a consumer in parallel to eliminate the queuing time due to lock or the like. CONSTITUTION:An intermediate buffer 14 is provided correspondingly to each processor 10 for the purpose of avoiding the access contention for data write to a main buffer 17. Consequently, since the intermediate buffer 14 is not accessed by the other producers 13 when one producer 13 writes data in the intermediate buffer 14, exclusive control due to lock is unnecessary. When data is written in the main buffer 17, exclusive control due to lock is unnecessary because a merger process 15 as the single process performs the data write. Thus, data write in the merge operation is not queued by access contention. |
