Abstract
The present invention relates to an apparatus and method for controlling a CPU clock in response to certain events with a system in order to conserve power usage. These events can be programmably enabled or disabled. The apparatus comprises a circuit for detecting enabled Stop Clock events requiring the CPU clock to temporarily cease operation. In combination therewith, the present invention includes a circuit for detecting enabled Stop Break events which are used to re-start the CPU clock. The present invention further comprises a Speedup circuitry to increase the CPU clock speed for enabled speedup events which are dependent on CPU clock speed.
