    摘要: In an embodiment, a processor includes first logic to determine first power to be provided to a first portion of a computational resource during a time period. The first portion may be reserved for execution by the processor of a first workload to be executed during the time period. The first power may be determined based at least in part on the first workload and independently of a second workload. The processor may include second logic to determine second power to be provided to a second portion of the computational resource during the time period. The second portion may be reserved for execution by the processor of the second workload during the time period. The second power may be determined based at least in part on the second workload and independently of the first workload.

    摘要: 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.

    摘要: Embodiments of the present invention provide for adaptively tuning the memory idle timer value in real time. Selected memory idle clock cycles are sampled to dynamically determine an optimized memory idle timer value. To optimize latency during sampling, the number of page hits (NPH) and number of page misses (NPM) are multiplied by weighted values WPH and WPM, respectively, such that the weighted function (WPH*NPH)−(WPM*NPM) is maximized. The weight associated with a page miss (WPM) is greater than the weight associated with a page hit (WPH), resulting in a bigger penalty for a page miss than a page hit. The selected setting is continuously optimized.

    摘要: 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.

    摘要: Techniques for generating information identifying a next direct memory access (DMA) task to be serviced. In an embodiment, arbitration logic provides a sequence of masking logic to determine, according to a hierarchy of rules, a next task to be serviced by a DMA engine. In certain embodiments, masking logic includes logic to mask information representing pending tasks to be serviced, the masking based on identification of a channel as being a suspended channel and/or a victim channel.
