Japanese Patent JP6810962
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable reduction of a process load on a processor, and also reduction of development costs for a program to be executed by the processor.SOLUTION: In an image processing device, a data transferring device 30 can be connected to an external storing device 3 that is communicable in accordance with a technical standard. The data transferring device 30 includes: an input and output I/F circuit 32 that acquires, from a bus master device, a first read-out request which contains a first data range at the bus side for data stored in the external storing device 3 and to be read; a control circuit 35 which creates a second data range in the external storing device 3 and containing data corresponding to the first data range on the basis of the first read-out request, and which creates a second read-out request containing the second data range; and a transferring circuit 33 that transmits the second read-out request. The input and output I/F circuit 32 is caused to extract, from the data on the data range corresponding to the read second read-out request, the data corresponding to the first data range, and to transmit the extracted data to the bus master device.SELECTED DRAWING: Figure 2
