Abstract

To provide a data processing apparatus equipped with a control means to reduce the power required for memory accessing, in spite of the unavailability of a repeat instruction, by reading instructions reiteratively from a small scale buffer in loop processing. Also to provide a data processing apparatus equipped with a means to opt to apply, or not to apply, control to read instructions, that have to be executed reiteratively in loop processing, out of a small scale buffer reiteratively.If, as a result of execution of an instruction to alter the content of a certain register prior to a series of instructions to be executed reiteratively, the register satisfies a specific condition, the series of instructions to be executed repeatedly are read out of a small scale buffer reiteratively.A data processing apparatus equipped with a control means to reduce the power required for memory accessing, in spite of the unavailability of a repeat instruction, by reading instructions reiteratively from a small scale buffer in loop processing can be provided. Also a data processing apparatus equipped with a means to opt to apply, or not to apply, control to read instructions, that have to be execut…
