    摘要: In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices. Even when the name corresponding to the data is not registered so that it is impossible to transfer the corresponding name instead of transferring the data, it is possible to reduce the amount of transfer data among the data transfer devices by transferring the compressed data in which this data is expressed in a compressed form by utilizing the name corresponding to the registered reference data.

    摘要: A decoding unit is arranged between a reading unit that reads data with an error correction code added from memory cells on a specific one of the first data lines and an output unit that selectively outputs certain data of the read out data. The decoding unit corrects any errors in the data read out by the reading unit in accordance with the error correction code. The data in which the errors are corrected by the decoding unit is written back in the memory cells on the specific first data line.

    摘要: A cache memory has a data holding unit, having multiple cache lines each of which includes an address area, a data area and a dirty bit, and a controller which is given read data and a correction execution signal indicating whether or not error correction has been performed for the read data, the read data has been read from a memory storing error-correction-coded data, which also stores address information corresponding to the read data into the address area of any one of the multiple cache lines, stores the read data into the data area, and sets a predetermine value as the dirty bit on the basis of the correction execution signal.

    摘要: A parity adder obtains a second data by adding a parity for first data to be written to a memory to the first data. An access-key register holds an access key unique to a source of request. A first operating unit obtains a third data by calculating an XOR between the second data and the access key, the access key being set by the source of request for writing data to the memory. A second operating unit obtains a fourth data by calculating an XOR between the access key and the third data. A syndrome calculator calculates a syndrome from the third data, the access key being set by the source of request for reading data from the memory. A determining unit determines whether to output the third data as the first data, based on calculated syndrome.
