<p>The data processing apparatus has first and second storages (10-1, 10-2) each independently accessible. An instruction unit (1, 2, 3, 4, 8) applies a fetch request on a one-operand instruction to the first storage, and a fetch request on a two-operand instruction to the first and second storages. In case of a fetch request on a two-operand instruction, a storage control unit (19) instructs the instruction unit to produce again a fetch request if one of the first and second storages is busy, and execute reading the operands in the order of decoding instructions.</p> |
