DMA TRANSFER RELAY DEVICE, DMA TRANSFER METHOD AND DMA TRANSFER SYSTEM

摘要

PROBLEM TO BE SOLVED: To allow connection to buses having different interfaces, and to realize efficient DMA transfer processing regardless of the amount of data requested for transfer.;SOLUTION: Data transferred to a DMA transfer relay device are temporarily stored in a storage means of the same capacity as a cache line size of a CPU, a signal (status data or the like outputted by a DMA controller) related to the data or the data transfer processing is detected, and the temporarily stored data are transferred to a prescribed data storage part on the basis of the detected signal.;COPYRIGHT: (C)2005,JPO&NCIPI
