Abstract
A data relaying apparatus and method capable of relaying data in a highly efficient manner. Data of a predetermined read-ahead size is acquired from the storage apparatus from a top address indicated by a data read request to temporarily store the data as temporary storage data and, each time a subsequent data read request is made, data of a transmission data size corresponding to a type of the subsequent data read request is read out sequentially from a top position of the temporary storage data to relay the data to a data processing apparatus.
Claims10
A data relaying apparatus having a relaying part that acquires data stored in a storage apparatus via a second data bus in response to a data read request arriving from a data processing apparatus via a first data bus to relay the data to the data processing apparatus via the first data bus, comprising:
- a temporary storage part that acquires data of a predetermined read-ahead size from the storage apparatus from a top address indicated by the data read request to temporarily store the data as temporary storage data, wherein
- each time a subsequent data read request is made, the relaying part reads out data of a transmission data size corresponding to a type of the subsequent data read request sequentially from a top position of the temporary storage data to relay the data to the data processing apparatus.
A data relaying method having a relaying step of acquiring data stored in a storage apparatus via a second data bus in response to a data read request arriving from a data processing apparatus via a first data bus to relay the data to the data processing apparatus via the first data bus, comprising:
- a temporary storage step of acquiring data of a predetermined read-ahead size from the storage apparatus from a top address indicated by the data read request to temporarily store the data as temporary storage data, wherein
- at the relaying step, each time a data request is made, data of a transmission data size corresponding to a type of the data request is relayed sequentially from a top position of the temporary storage data to the data processing apparatus.
