ABSTRACT:
An information processing apparatus with an instruction prefetch unit is disclosed, in which a CPU operation can be stopped at a desired address in response to a break signal. The instruction prefetch unit has an instruction prefetch circuit storing an instruction and an indication register storing the break signal. A read operation and a write operation of the indication register are executed together with those of the instruction prefetch circuit. Thus, a break point can be set a desired address by using the indication register, and the break operation can be correctly preformed without the need for complex hardware.
