Abstract: In examples, a virtual channel allocated to a virtual machine may be used to transmit image data representing a display surface to memory assigned to the display surface in a virtual address space of the virtual machine. A physical display engine may be configured to fetch the image data from the memory, perform desired transformations, and send the resulting output to the display surface to display. Privileged software may process requests from virtual machines for allocations or configurations of display surfaces and configure the physical display engine, a memory system, and/or other system components accordingly. Software running on a virtual machine may use virtual channels to submit the requests and transmit image data for display surfaces to memory using the virtual address space. A virtual channel may be provided by a virtual network adapter assigned to the virtual machine.

Abstract: A graphics server for remotely rendering a composite image and a method of use thereof. One embodiment of the graphics server includes: (1) a graphics renderer configured to render updates for a plurality of graphics windows within the composite image and (2) a display processing unit (DPU) configured to identify changed portions of the composite image and provide the changed portions to an encoder for encoding and subsequent transmission.

Abstract translation: 用于远程渲染合成图像的图形服务器及其使用方法。 图形服务器的一个实施例包括：（1）图形渲染器，被配置为呈现合成图像内的多个图形窗口的更新;以及（2）配置为识别合成图像的改变部分并提供 改变的部分到编码器和后续传输的编码器。

Abstract: A liquid crystal display (LCD) overdrive interpolation circuit and method, and an LCD drive system incorporating the circuit or method. In one embodiment, the circuit includes: (1) a diagonal interpolator operable to perform a diagonal interpolation along a diagonal direction in a lookup table based on TO and FROM gray levels and (2) a further interpolator coupled to the diagonal interpolator and operable to perform a further interpolation based on a result of the diagonal interpolation and the FROM gray level.
