Abstract:
1. A communication terminal comprising: a storage section configured to store a file to be transmitted to an opponent terminal; a communication section configured to transmit the file to the opponent terminal; a cluster information calculation section configured to determine cluster information about a cluster for each set of data to be transferred; and a DMA transfer section configured to DMA-transfer the file from the storage section to the communication section on the basis of the cluster information about the cluster to be transferred that the cluster information calculation section determined, wherein the cluster information calculation section is adapted to request cluster information about a next cluster to be transferred during the course of DMA transfer, and wherein the cluster information calculation section includes a cluster search volume calculation section configured to calculate a volume of cluster search; a cluster search section configured to search the storage section for clusters in accordance with a calculation result of the cluster search volume calculation section; a file management section configured to manage the storage section by use of a predetermined file system; and a DMA control section configured to set in the DMA transfer section cluster information about the clusters that make up the file to be DMA-transferred, on the basis of in accordance with a calculation result of the cluster search section and the file system.
