    摘要: Each of (n−1) 2-bit checking units, where n is an integer larger than or equal to 4, receives n-bit redundant encoded data generated from 1-bit input data, and outputs 2-bit check data based on a result of comparison between bits of the encoded data, combinations of the bits differing in each comparison. An all-bit checking unit outputs all-bit check data based on exclusive ORs of all-bit of the encoded data. An error detecting unit detects errors in the encoded data on the basis of the (n−1) sets of 2-bit check data and the all-bit check data, and outputs the input data on the basis of the result of error detection.

    摘要: A DMA circuit prevents an erroneous data transfer by a descriptor due to an address failure of memory. When a descriptor is created, the data processing unit writes a pointer, for storing the descriptor, in a predetermined part of the descriptor, and stores the descriptor in memory, and when a DMA engine reads the descriptor from the memory, the DMA engine confirms whether the value is correct, and judges whether a DMA transfer of the data in the memory is possible. For both reading and writing of a descriptor, data corruption due to an address failure can be prevented.

    摘要: A crypt processor is connected to a host computer and a storage apparatus. Data from the host computer is transferred to the crypt processor via DMA (Direct Memory Access) to be encrypted and then stored in the storage apparatus. The crypto processor acquires a descriptor defining a DMA number for identifying a DMA channel used to DMA-transfer the data. The crypto processor stores therein, based on the DMA number included in the acquired descriptor, the data transferred using the same DMA channel in units of a data size specified in a data bus. The crypto processor then encrypts the stored data in units of data size specified in a crypt system, and transfers the encrypted data to the storage apparatus.

    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.

    摘要: Priorities are set in order of an internal register access packet, a response system packet, and a command system packet which are transmitted/received by a packet transmitting/receiving unit. In a transfer waiting state of the command system packet of the low priority to a certain transmission destination, in the case where the response system packet or internal register access packet of the high priority to another transmission destination is received from an external module, the packet transmitting/receiving unit withdraws the transfer waiting state and transmits the packet of the high priority.
