PROBLEM TO BE SOLVED: To solve the problem of a deadlock or the like in a data processing system due to a write command. SOLUTION: A header analysis unit N<SB>i1</SB>, when receiving a write command from a node N1, simultaneously notifies a response generation unit N<SB>i3</SB>about Requester ID information and issues a write command to a memory control unit N<SB>i2</SB>. The memory control unit N<SB>i2</SB>writes in a memory and notifies the response generation unit N<SB>i3</SB>about the write command completed and the redundant code of written data. The response control unit N<SB>i3</SB>sends a CplD having a Tag ID with a predetermined value to the node N1, which is the sender of the write command. The node N1 reports the completion of the write command to a DMA Engine N<SB>i4</SB>based on the Tag ID of the Cpl ID received. COPYRIGHT: (C)2009,JPO&INPIT
