摘要： A dynamic performance circuit adjustment system and method that flexibly adjusts the performance of a logic circuit. The dynamic performance circuit adjustment system and method facilitates flexible power conservation. In one exemplary implementation, a dynamic performance adjustment control circuit controls performance adjustments to a logic circuit (e.g., a processor) and adjusts support functions for the logic circuit. The logic circuit performs operational functions (e.g., processing) or tasks that have different performance requirements. For example, some tasks performed by the logic circuit are required to be performed in a relatively short duration of time and other tasks performed by logic circuit have relatively longer time limitations. The dynamic performance adjustment control circuit adjusts the clock frequency and voltage at which the logic circuit operates to a relatively greater frequency and voltage for tasks required to be performed in a shorter duration of time and adjusts the frequency and voltage at which the logic circuit operates to a relatively lower frequency and voltage for tasks with longer timing tolerances. The dynamic performance adjustment system and method includes provisions to manage a transition in performance and support functions in a manner that reduces the risk of spurious signals or “glitches.”

摘要： Embodiments of this invention provide for a portable computer that determines whether an accessory device is actively connected to it. In one embodiment, the portable computer may include a signal line accessible through an output of the portable computing device. The signal line may be connected to a communication device such as a communication cradle. The portable computer may detect a signal on the signal line to determine whether the communication device is actively connected to the portable computer. If the communication device is actively connected, the portable computer suspends implementation of a time-out feature that would otherwise reduce power consumption of the portable computer.

摘要： A personal communication device which includes the ability to generate dual tone multi-frequency (DTMF) signals to provide automatic telephone dialing of a numbers received in messages. A message which includes a number is received, decoded, and displayed on a display device. The user may then select to have a number which is included as part of the message encoded into an audible DTMF, series of signals which can be coupled to a conventional “touch-tone” telephone (i.e. a telephone that supports tone dialing) through speaker in the personal communication device and the microphone of the conventional telephone. The user may select all or any part of the message to be encoded into DTMF signals. Accordingly, if the message includes other information in addition to a telephone number, the user can parse the message to indicate which portion of the message includes the number to be dialed. In an alternative embodiment of the present invention, a processor within the personal communication device parses the message to detect numbers from among the information that has been transmitted. The user may then verify that the processor has properly identified numbers which the user wishes to encode in DTMF signals.
