Abstract

The data processing apparatus has first and second storages each independently accessible. An instruction unit 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 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 of instructions.
