<P>PROBLEM TO BE SOLVED: To efficiently transfer data between different OSs even when a size of a shared memory is limited. <P>SOLUTION: In the case that a data transfer instruction for transferring data from a first OS to a hardware device managed by a second OS is issued to the first OS, the data of a transfer object by the data transfer instruction is divided into two or more pieces of division data of a size smaller than a usable size of a shared memory to be shared and used by the first OS and the second OS and written to the shared memory. A division data transfer command specifying the data size of the division data as a transfer size is generated and issued to the second OS every time the division data is written to the shared memory so that the division data written to the shared memory is read in the second OS and transferred to the hardware device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
