    摘要： A multiplexing bus controller with input conditioning is provided in which the need for a dedicated microprocessor for handling input filtering, input change detection and serial-to-parallel/parallel-to-serial I/O data conversion is eliminated. The controller is realized in a gate array and provides input data oversampling and output refreshing to eliminate random noise coupled to the data lines. In addition, the oversampled data is filtered to debounce the signal received from the input devices. The input data is converted from serial-to-parallel and checked to detect any change from the previous input data stream. Upon detection of an input change, the host microprocessor is interrupted. When the host microprocessor sends data to the bus controller, the bus controller then converts the data to a serial stream for communication to the appropriate output device. Additionally, the bus controller is provided with an internal turnaround circuit to loop back outputs to the inputs for diagnostic purposes. Very low gate counts realized in the design of the multiplexing bus controller allow it to be realized on a single chip.

    摘要翻译： 提供了一种具有输入调节功能的复用总线控制器，其中消除了用于处理输入滤波，输入变化检测和串并行/并 - 串行I / O数据转换的专用微处理器的需要。 控制器在门阵列中实现，并提供输入数据过采样和输出刷新，以消除耦合到数据线的随机噪声。 另外，对过采样数据进行滤波以去除从输入设备接收的信号。 输入数据从串行到并行转换，并检查以检测来自先前输入数据流的任何变化。 当检测到输入变化时，主微处理器被中断。 当主机微处理器向总线控制器发送数据时，总线控制器然后将数据转换为串行流，以通信到适当的输出设备。 此外，总线控制器设置有内部周转电路，用于将输出回送到输入用于诊断目的。 在多路复用总线控制器的设计中实现的非常低的门计数允许其在单个芯片上实现。

    摘要： Various disclosed help center features provide help to a user without a staffed help center, provide help to a user before the user recognizes the need, or create targeted commerce opportunities for a provider of goods or services. One help center feature provides a user with help that is specifically related to a component in the user's computer system and that is supplied to the help center feature by the component manufacturer. Another help center feature detects a condition that degrades performance, and hence user satisfaction, and alerts the user. Another help center feature detects an attempt by a computer system to inform the user of degraded performance and offers the user a solution. Another help center feature provides a user with a commerce opportunity specifically related to a component in the user's computer system and/or to the user's geographic location.
