摘要： Embodiments herein relate to providing uniform servicing of workloads at a set of servers in a computer network. A platform determines and meets the performance requirements of a workload by scaling a performance capability of a group of processing units such as central processing units (CPUs) which are assigned to service the workload. This can involve increasing the power (P) state of one or more of the processing units to a highest P state in the group, so that every processing units in the group provides the same performance for a given workload. The platform can manage scaling of the processing units performance by reading a performance profile list which indicates minimum and maximum scaling points for programs that are executed to service the workload.

摘要： A Peripheral Component Interface Express (PCIe) card includes a circuit board, a device mounted on the circuit board, and a PCIe processor mounted on the circuit board. The PCIe processor is communicatively coupled to the device and a host processor of a host system. The PCIe processor is configured to detect a power signal on an auxiliary (AUX) power rail of the PCIe card. A periodic detection of a state of the device is performed based on detecting the power signal on the AUX power rail. A signal indicative of the state of the device is encoded for transmission to the host processor of the host system. PCIe link training is performed via a PCIe interface with the host system. The PCIe link training is initiated based on the signal indicative of the state of the device.

摘要： A system and method for intelligent decoded picture buffering is described. In one embodiment, a video bitstream buffer receives and temporarily holds an encoded compressed bitstream containing portions of a video. Then, a look ahead parser scans ahead in the video to analyze portions of the encoded video bitstream in the video bitstream buffer to predict the value of the video. Based on this prediction, an intelligent memory manager prioritizes the video portions, and then sends the high valued video portions to a first buffer and sends the low valued video portions to a second buffer.

摘要： A Quality of Experience (QoE) framework provides a technique to assess the end user experience in a mobile wireless communication environment, such as 2.5G or 3G networks, or in any other wireless or hardwired communication environment. The framework is usable in conjunction with media streaming applications and enables a combination of network layer, transport layer, codec layer, and application layer measurements in extracting results. The extracted results can be used to monitor and improve, if necessary, the end user experience over severely variable network conditions.

摘要： The motion estimation techniques and video encoding device(s) described use a two dimensional pipeline to generate accurate motion estimation parameters for a current video block. The two dimensional pipeline uses previously calculated motion estimation parameters of relevant neighboring video blocks, including a preceding video block on a same row as the current video block, prior to the generation of the accurate motion vectors, motion vector predictors, and mode decision of the current video block The use of the two dimensional pipeline allows accurate motion vector prediction from neighboring video blocks previously not available, in the computation of motion vectors. Three engines may be used in the two dimensional pipeline, a fetch engine, an integer search engine and a fractional and spatial search engine. While the fetch engine and fraction and spatial search engine operate on one row, the integer search engine operates on another row.
