    摘要: A DMA circuit operates a plurality of DMA channels in parallel, enabling reduction of the circuit scale and fewer development processes. A channel manager circuit reads in sequence the control information for each DMA channel from control memory, performs analysis, and according to the divided DMA control sequence, performs state processing (DMA control). Further, the channel manager circuit updates the control information, writes back the control information to the control memory, and executes time-division control of the plurality of DMA channels. Hence the circuit scale can be reduced, contributing to decreased costs, and the number of development processes can be reduced.

    摘要: Arbitrary data is read out from a main storage device, based on a permanent fault detection address that is used to detect a permanent fault on an address line. A bit error in the permanent fault detection address is detected and corrected, based on an error correcting code included in the arbitrary data read out. A permanent fault on the address line is determined, based on results of the error detection/correction.

    摘要: To be able to transmit a response packet to a target, which is the original request source node, even if, after issuing a request from a node to another, a bus ID/a device ID is replaced in the PCI-Express switch before said another node makes a response to the request source node in a PCI-Express communication system, which uses a PCI-Express switch. For that purpose, a unique node ID for indicating each node is set to the nodes, a channel ID is set to each channel used for data transfer, and the node ID of the transfer destination module, the channel ID of a channel used for the data transfer, and the packet type indicating that the packet is a request or a response are set in an address field of a packet of data transfer. For the data transfer, only a memory write request packet routed by address routing is used.
