摘要： A sense amplifier circuit for use with a directory memory chip in which the output of a corresponding memory cell is sensed and output signals representing the sensed bit state are provided to first and second output ports. The signal provided to the first output port can be selectively inhibited, although, when not inhibited, the signals applied to the first and second output ports occur simultaneously. The inhibiting function may be performed by a dual-emitter circuit and switchable current source in one of two sense amplifiers.

摘要： An activity poller on an external graphics box is activated during inactivity in communication from a host information handling system to the external graphics box, such as over an external PCI Express cable. The activity poller periodically sends a memory read request from the external graphics box to the host information handling system through the PCI Express cable and analyzes the response to determine the operational state of the host information handling system. Failure of the host information handling system to respond to the polling for a predetermined time results in presentation of a locally generated diagnostic message at the external graphics box, such as message stored in shader instructions of the external graphics box.
摘要翻译：在从主机信息处理系统到外部图形盒的通信中不活动时，例如通过外部PCI Express电缆，外部图形盒上的活动轮询器被激活。活动轮询器通过PCI Express电缆定期从外部图形盒发送存储器读取请求到主机信息处理系统，并分析响应以确定主机信息处理系统的操作状态。主机信息处理系统在预定时间内响应轮询的失败导致在外部图形盒处呈现本地生成的诊断消息，诸如存储在外部图形盒的着色器指令中的消息。

摘要： An improved system and method for selectively applying LCD Response Time Compensation (LRTC) to areas of an LCD panel containing video motion. Motion vectors contained within macroblocks in a compressed video stream are utilized to qualify whether individual pixels in a video frame are a candidate for LRTC. In various embodiments of the invention, computationally expensive LRTC can be selectively applied, pixel-by-pixel, which can result in portable information system power savings by reducing the number of computational cycles and the amount of graphics controller power overhead.

摘要： Hot connection and disconnection of an external graphics cable with an information handling system provides automatic selection of an external graphics device or an internal graphics device for presentation of visual information. A graphics state module periodically stores visual information, such as display objects for recreating a display frame, and monitors an external graphics device port, such as a PCI Express port, to detect a change in connection state at the external graphics port. Upon detection of a connection or disconnection at the external graphics port, the graphics state module attempts to initiate graphics devices in a predetermined order and provides the stored visual information for presentation at successfully initiated graphics devices according to the predetermined order.
