System for reducing processor power consumption by stopping processor clock supply if a desired event does not occur

摘要: An apparatus and method are provided for disabling the clocking of a processor in battery operated computer during non-processing times. The is disabled at conclusion processing operation. can then be re-enabled using interrupts from any one plurality sources, such as an I/O device or direct memory access. Application programs operating system running on specify stopping clock central until specified event which had been requested occurs, optional time-out period has expired. In this situation, defined that results either interrupt access two part operation wherein first mechanism armed. If received subsequent to arming, it will processed arming reset. However, if does not occur after within time period, stopped.
