INFORMATION PROCESSOR, DATA TRANSFER METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable immediately starting data transfer to an I/O device, and to stably exerting data transfer performance. SOLUTION: In this information processor equipped with hardware for sharing an address conversion table for converting the logical address of a memory 14 into a physical address between a main processor 14 and a sub-processor 24, one of the sub-processors 24 is made to function as a means for accepting a transfer request to designate the logical address of the memory 14, a means for converting the logical address designated in the transfer request into the physical address by using the shared address conversion table; and a means for executing the transfer processing of data stored in the memory 14 according to the converted physical address.
