    • A real-time power conservation and thermal management apparatus and method for portable computers employs a monitor (40) to determine whether a CPU may rest based upon a real-time sample of the CPU activity and temperature levels and to activate a hardware selector(500, 510, 520, 530) to carry out the monitor's determination. If the monitor determines the CPU may rest, the hardware selector reduces CPU clock time (280); if the CPU is to be active, the hardware selector returns the CPU to its previous high speed clock level (330). Switching back into full operation from its rest state occurs without a user having to request it and without any delay in the operation of the computer while waiting for the computer to return to a “ready” state. Furthermore, the monitor adjusts the performance level of the computer to manage power conservation and thermal management in response to the real-time sampling of CPU activity (10) and temperature (24). Such adjustments are accomplished within the CPU cycles and do not affect the user's perception of performance and do not affect any system application software executing on the computer.
    • 一种用于便携式计算机的实时功率节省和热管理装置和方法,使用监视器(40)来确定CPU是否可以基于CPU活动和温度水平的实时采样来休息,并激活硬件选择器(500 ,510,520,530),以执行监视器的确定。 如果显示器确定CPU可能休息,硬件选择器可以减少CPU时钟时间(280); 如果CPU处于活动状态,硬件选择器将CPU返回到其先前的高速时钟电平(330)。 在等待计算机返回到“准备就绪”状态的同时,不用用户不需要请求并且没有任何延迟的计算机的运行而发生从其休息状态的全部操作。 此外,监视器根据CPU活动(10)和温度(24)的实时采样来调整计算机的性能水平,以管理节能和热管理。 这些调整是在CPU周期内完成的,不会影响用户对性能的看法,也不影响在计算机上执行的任何系统应用软件。

    • In order to provide continuous communication ability in a computer architecture that integrates a computer (PC) architecture system and a personal digital assistant (PDA) architecture system, a common communication device is provided. Independent access is made available to the communication device to either the PC or the PDA depending on which system is in control. A switch isolates either the PC or PDA to control of the communication device and other common peripherals. The PDA can be a slave device to the PC, with both systems synchronized with one another and able to exchange information and data. Because the PDA consumes much less power than the PC, the PDA can remain active while the PC is shut off. Because the PDA has the ability to communicate the computer continues to receive and transmit messages and information.
    • 为了在集成计算机(PC)架构系统和个人数字助理(PDA)架构系统的计算机架构中提供连续的通信能力,提供了公共通信设备。 根据哪个系统可以控制,独立访问可以由通信设备提供给PC或PDA。 一个开关将PC或PDA隔离开来控制通信设备和其他通用外围设备。 PDA可以是PC的从设备,两个系统彼此同步并能够交换信息和数据。 因为PDA比PC消耗的功率要少得多,所以在PC关闭时,PDA可以保持活动状态。 因为PDA具有通信的能力,继续接收和发送消息和信息。

    • A portable system is provided with both an ISPCA processing section, a non-standard personal computer architecture (NSPCA) processing section and a common section including apparatus common to both processing sections. The NSPCA processing section operates under an operating system such as the WINDOWS® CE operating system, having reduced functionality, but being capable of “instant-on” operation. The data processing system includes controllable reduced power (and reduced functionality) mode wherein only the NSPCA processing is activated. The data processing system can controllably be transferred to a higher power (and full functionality) mode operating by activating the ISPCA processing section. In this manner, the processing section that is not an integral part of the data processing system can be detachably coupled thereto.
    • 便携式系统具有ISPCA处理部分,非标准个人计算机体系结构(NSPCA)处理部分和包括两个处理部分共同的设备的公共部分。 NSPCA处理部分在诸如WINDOWS CE操作系统的操作系统下操作,功能降低但能够“即时启动”操作。 数据处理系统包括只有NSPCA处理被激活的可控降低功率(和功能降低)模式。 通过激活ISPCA处理部分可以将数据处理系统可控地转移到更高功率(和全功能)模式。 以这种方式,不是数据处理系统的组成部分的处理部分可以可拆卸地耦合到其上。

    • In order to overcome the relatively short battery life and the relatively long delay between the activation and the actual functioning of a typical mobile computing system, the mobile computing system is provided with a personal computer (PC) architecture system and a personal digital assistant (PDA) architecture system, and a common display and shared peripherals. Interfacing to the systems is a super input output or embedded controller (SIO/EC) that acts as a slave device to whatever system has control of computing system. The SIO/EC controls a quick switch which blocks or allows communication along communication busses connecting the systems to the SIO/EC. A user can selectively change, by way of a user interface to the SIO/EC, to whatever system that is desired by the user.
