    • A multiple use core logic chip set is provided in a computer system that may be configured either as a bridge between an accelerated graphics port (“AGP”) bus and host and memory buses, as a bridge between an additional registered peripheral component interconnect (“RegPCI”) bus and the host and memory buses, or as a bridge between a primary PCI bus and an additional RegPCI bus. The function of the multiple use chip set is determined at the time of manufacture of the computer system or in the field whether an AGP bus bridge or an additional registered PCI bus bridge is to be implemented. The multiple use core logic chip set has an arbiter having Request (“REQ”) and Grant (“GNT”) signal lines for each PCI device utilized on the additional registered PCI bus. Selection of the type of bus bridge (AGP or RegPCI) in the multiple use core logic chip set may be made by a hardware signal input, or by software during computer system configuration or power on self test (“POST”). Software configuration may also be determined upon detection of either an AGP or a RegPCI device connected to the common AGP/RegPCI bus.

    • A method and system for controlling the power supply fan in a computer system. The speed of a power supply fan can be made directly proportional to the temperature of the power supply. The fan speed can also be controlled by a processor with software commands according to the temperature of the processor. The speed of the fan will be dictated by the higher of the two commands driving it. Therefore, the power supply fan can never be commanded by the processor to run at a lower speed than that required by its own thermal environment. A Fan Speed Control Circuit enables the computer system to command the power supply fan to run at a higher speed. The processor temperature can be monitored with a temperature transducer and analog signal conditioning circuitry.
    • 一种用于控制计算机系统中的电源风扇的方法和系统。 电源风扇的速度可以与电源的温度成正比。 风扇速度也可以由具有根据处理器温度的软件命令的处理器控制。 风扇的速度将由驱动它的两个命令中的较高者决定。 因此,电源风扇永远不能被处理器命令以比其自身热环境所要求的速度更低的速度运行。 风扇速度控制电路使计算机系统能够使电源风扇以更高的速度运行。 可以使用温度传感器和模拟信号调理电路来监控处理器温度。

    • A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes. The instruction set is limited to register-to-register operations and register load/store operations. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken. Another performance improvement makes use of unused bits in the standard. sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like. The target can thus be prefetched before the actual address has been calculated and placed in a register. In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed.
    • RISC(精简指令集)类型的高性能CPU采用标准化的固定指令大小,并且仅允许简化的存储器访问数据宽度和寻址模式。 指令集仅限于寄存器到寄存器操作和寄存器加载/存储操作。 可以通过预测分支的目标并基于该预测来预取新指令来加快性能; 遵循分支预测规则,要求将所有前向分支预测为未被采用,并且所有后向分支(如循环常用)被预测为采用。 另一个性能改进使得在标准中使用未使用的位。 提供预期目标地址的提示以跳转和跳转到子程序指令等。 因此,可以在实际地址被计算并放置在寄存器中之前预取目标。 此外,跳转指令的未使用的位移部分可以包含一个字段来定义跳转的实际类型,即跳转,跳转到子程序,从子程序返回,从而将预测的目标地址放在堆栈中,以便在 指令已执行。

    • A portable computer system with planar speakers. The planar speakers are fabricated with a coplanar array of small, low cost, durable, electromagnetic speaker elements mounted on a panel. The planar speakers can be attached to the lid of the computer system. The planar speakers can slide into a compartment in the lid of the computer system when not in use and slide out of the compartment for use with greater physical separation than that of built-in speakers. Alternatively, the planar speakers are attached to the lid via a hinge and folded against the lid when not in use. The planar speakers are folded outward extending the planar speakers beyond the lid for use with greater physical separation than that of built-in speakers. The planar speakers can be detachable from the remainder of the computer system for greater spacing and variable positioning of the planar speakers for improved stereo sound reproduction. Detached planar speakers also permit transport or storage of the planar speakers separately from the remainder of the computer system. Such planar speakers also have application in portable music reproduction devices and, in larger area form, for use in home audio systems.
    • 具有平面扬声器的便携式计算机系统。 平面扬声器由安装在面板上的小型,低成本,耐用的电磁扬声器元件的共面阵列制造。 平面扬声器可以连接到计算机系统的盖子上。 当不使用时,平面扬声器可以滑入计算机系统的盖子中的一个隔间,并从室内滑出,比内置扬声器更大的物理分离使用。 或者,平面扬声器通过铰链附接到盖子,并且在不使用时折叠在盖子上。 平面扬声器向外折叠,将平面扬声器向外延伸超过盖,用于比内置扬声器更大的物理分离。 平面扬声器可以与计算机系统的其余部分分离,用于平面扬声器的更大间隔和可变定位,以改善立体声再生。 独立的平面扬声器还允许平面扬声器与计算机系统的其余部分分开运输或存储。 这样的平面扬声器也可用于便携式音乐再现设备中,并且在较大的区域形式中也可用于家用音频系统。
