| 主权项 | 1. A data transfer control apparatus comprising: a transferring unit configured to transfer data from a transfer source memory to a transfer destination memory, according to an instruction from a first processor; and a first processor configured to: detect a process being executed by the first processor, determine whether transfer of the data is urgent, based on the type of the detected process, and control the transferring unit to transfer the data or control the first processor to read the data from the transfer source memory or the transfer destination memory, based on a determination result, wherein the first processor further detects that a state of the process changes from an active state to an inactive state or from the inactive state to the active state, and the first processor determines whether the transfer of the data is urgent, based on the type of the process and a detection result concerning the state of the process. | ||
