System for controlling operation of processor by adjusting duty cycle of performance control pulse based upon target performance value

摘要

A system for adjusting a performance of an information processing apparatus which provides a unit indicating a target performance value, a unit generating a corresponding performance control pulse in accordance with the target performance value, and an execution control unit which alternately sets an execution period and an execution inhibiting period in accordance with the performance control pulse. The unit which generates the performance control pulse sets a ratio of a pulse width and a pulse period of the performance control pulse coincide with the target performance value.
