    摘要: A pointer comparing unit determines whether a value of a writing pointer is identical to a value of a reading pointer. When it is determined that the value of the writing pointer is different from the value of the reading pointer, an inter-memory transfer unit reads data stored in a location where a data transfer apparatus reads transmission data from a transmission ring buffer, transfers the data to a reception memory, and writes the data in a location designated by the reading pointer of a reception ring buffer. When the inter-memory transfer unit completes writing of the data in the reception ring buffer, a reading-pointer updating unit updates the reading pointer.

    摘要: A bus bridge device, which connects a first device executing a first process and a second device executing a second process in response to a request from the first device, includes a notifying unit that notifies, when a result of the second process is received from the second device, the result to the first device. The first device executes, after sending the request, a third process until the result is notified from the notifying unit.

    摘要: A memory includes a set of sequentially stored data. Each of the data includes a variable-length data and length information indicative of a data length of the variable-length data. An MPU creates a read instruction for reading the set of data. A DMS chip, upon receiving the read instruction, reads length information from the memory, calculates a storage location of subsequent data in the memory, and reads the subsequent data from the first memory. Thus, the DMS chip reads the subsequent data from the memory instead of the MPU thereby reducing load on the MPU.

    摘要: A data relay device relays a read request from a source device to a destination device and relays data corresponding to the read request from the destination device to the source device. The data relay device monitors elapsed time from a time point at which a read request is relayed to the destination device. When the elapsed time reaches warning time or error time, the data relay device sends a warning message or an error message to the source device.

    摘要: A method of writing data includes receiving a record of a variable-length data format, creating a field-checking code for each field of the record received, creating a block-checking code in units of the fixed-length data for the data received, and writing data by reading the record, assembling fixed length data that includes the field-checking code and the block-checking code by using the field-checking code and the block-checking code, and transferring the data to a cache memory.

    摘要: A data transferring apparatus receives comparison data to be compared with stored data from an external unit, searches data corresponding to the comparison data from among the stored data, and transfers the data searched to the external unit. A control unit generates comparison-condition information for searching predetermined stored data from a data storing memory. A comparison-data storing unit stores the comparison data received. A comparison-condition storing unit stores the comparison-condition information generated, upon the comparison-data storing unit storing the comparison data. A transfer processing unit transfers the stored data searched to the external unit.
