<p>A processor includes a data memory (11) storing data written by an arithmetic processing unit (20); a connecting unit (12) connecting an input path (L50) from the arithmetic processing unit (20) to the data memory (11) and an output path (L60) from the data memory (11) to a main storage unit (30); a selecting unit (14) provided on the output path (L60), to select data from the data memory (11) or data from the arithmetic processing unit (20) via the connecting unit (12), and to transfer the selected data to the output path (L60); and a control unit (13) controlling the selecting unit (14) such that the data from the data memory (11) is transferred to the output path (L60) when the data is written from the data memory (11) to the main storage unit (30), and such that the data is transferred to the output path (L60) via the connecting unit (12) when the data is written from the arithmetic processing unit (20) to the main storage unit (30).</p> |
