Abstract
PURPOSE:To improve data transfer efficiency by designating a position on an extension memory unit to use data at this designated position as an address and an access is given to the data pointed by said address for execution of the transfer of the data. CONSTITUTION:A user transmits a request to a data transfer means 203 to transfer the data having a link structure to a main memory unit (MMU) 201 from an extension memory unit (XMU) 204, and the means 203 is started. The means 203 gives an access to a link part 205 of the XMU 204 set at a position designated by the user and read out an address. Then the means 203 recognizes the position of a linked data part 206 and transfers the part 206 to the MMU 201 from the XMU 204. As a result, a data part 202 transferred to the position designated by the user on the MMU 201 is stored.
