    Abstract: Encoded data decoding techniques. A data decoding agent determines a data segment size for a packet that includes a header and a data segment. The data decoding agent determines a segment end location based, at least in part, on the data segment size. The data decoding agent processes subblocks of data from the data segment. The data decoding agent compares a current location to the segment end location to determine if a current subblock of data from the data segments contains the segment end location. The data decoding agent triggers an exception handler if the current subblock contains the segment end location.

    Abstract translation: 编码数据解码技术。 数据解码代理确定包括报头和数据段的分组的数据段大小。 数据解码代理至少部分地基于数据段大小来确定段结束位置。 数据解码代理处理来自数据段的数据的子块。 数据解码代理将当前位置与段结束位置进行比较，以确定来自数据段的当前数据子块是否包含段结束位置。 如果当前子块包含段结束位置，则数据解码代理触发异常处理程序。

    Abstract: The architecture and techniques described herein can improve system performance with respect to the following. Communication between two interdependent hardware engines, that are part of pipeline, such that the engines are synchronized to consume resources when the engines are done with the work. Reduction of the role of software/firmware from feeding each stage of the hardware pipeline when the previous stage of the pipeline has completed. Reduction in the memory allocation for software-initialized hardware descriptors to improve performance by reducing pipeline stalls due to software interaction.

    Abstract translation: 本文描述的架构和技术可以改善系统性能。 两个相互依赖的硬件引擎之间的通信是管道的一部分，使得引擎在引擎完成工作时同步以消耗资源。 当管道的上一个阶段完成时，减少软件/固件从硬件管道的每个阶段的角色。 减少用于软件初始化的硬件描述符的内存分配，以通过减少由于软件交互而导致的流水线停顿来提高性能。

    Abstract: An apparatus for secured playback is presented. In one embodiment, the apparatus includes a controller that includes a key derivation module to manage authentication and key derivation. In one embodiment, the apparatus provides a video decryption key to a graphics engine if video data portions in a data stream are retrievable without having to decrypt the data stream. In one embodiment, the apparatus also includes a decryption module to decrypt a part of data in conjunction with an encryption key to generate video information and video data. The controller then writes an encrypted version of the video data to a video buffer of a graphics engine.

    Abstract: A method and apparatus for creating, updating, and using guest physical address (GPA) to host physical address (HPA) shadow translation tables for translating GPAs of graphics data direct memory access (DMA) requests of a computing environment implementing a virtual machine monitor to support virtual machines. The requests may be sent through a render or display path of the computing environment from one or more virtual machines, transparently with respect to the virtual machine monitor. The creating, updating, and using may be performed by a memory controller detecting entries sent to existing global and page directory tables, forking off shadow table entries from the detected entries, and translating GPAs to HPAs for the shadow table entries.
