Abstract: An ingress packet processor in a device corresponds to a group of ports and receives network packets from ports in its port group. A traffic manager in the device manages buffers storing packet data for transmission to egress packet processors. An ingress arbiter is associated with a port group and connects the port group to an ingress packet processor coupled to the ingress arbiter. The ingress arbiter determines a traffic rate at which the associated ingress packet processor transmits packets to the traffic manager. The ingress arbiter controls an associated traffic shaper to generate a number of tokens that are assigned to the port group. Upon receiving packet data from a port in the group, the ingress arbiter determines, using information from the traffic shaper, whether a token is available. Conditioned on determining that a token is available, the ingress arbiter forwards the packet data to the ingress packet processor.

Abstract: Techniques and tools for encoding enhancement layer video with quantization that varies spatially and/or between color channels are presented, along with corresponding decoding techniques and tools. For example, an encoding tool determines whether quantization varies spatially over a picture, and the tool also determines whether quantization varies between color channels in the picture. The tool signals quantization parameters for macroblocks in the picture in an encoded bit stream. In some implementations, to signal the quantization parameters, the tool predicts the quantization parameters, and the quantization parameters are signaled with reference to the predicted quantization parameters. A decoding tool receives the encoded bit stream, predicts the quantization parameters, and uses the signaled information to determine the quantization parameters for the macroblocks of the enhancement layer video. The decoding tool performs inverse quantization that can vary spatially and/or between color channels.

Abstract: An audio encoder implements multi-channel coding decision, band truncation, multi-channel rematrixing, and header reduction techniques to improve quality and coding efficiency. In the multi-channel coding decision technique, the audio encoder dynamically selects between joint and independent coding of a multi-channel audio signal via an open-loop decision based upon (a) energy separation between the coding channels, and (b) the disparity between excitation patterns of the separate input channels. In the band truncation technique, the audio encoder performs open-loop band truncation at a cut-off frequency based on a target perceptual quality measure. In multi-channel rematrixing technique, the audio encoder suppresses certain coefficients of a difference channel by scaling according to a scale factor, which is based on current average levels of perceptual quality, current rate control buffer fullness, coding mode, and the amount of channel separation in the source.

Abstract: A more accurate model parameter estimation is achieved by using a Kalman filter for discretely estimating the model parameters between the consecutive frames of the frame sequence and performing the correction of the time-discrete Kalman filter twice per frame, firstly using a measurement value which depends on a complexity measure of the current frame to achieve a primarily corrected state of the time-discrete Kalman filter, and secondly using a measurement value depending on an actual coding rate or distortion of the video encoder in encoding the current frame using a predetermined quantization which may have been determined by an estimation of the actual rate- or distortion-quantization function according to the primarily corrected state. A rate-quantization model function relates the quantization of the video encoder to the coding rate of the video encoder and is piecewise defined to exhibit quadratic and exponential functions in finer and coarser quantization intervals, respectively.

Abstract: A multi-link input/output (I/O) interface uses both feed-forward and feedback signaling to reduce the impact of noise on data capture at a memory controller. To transfer data from a source module to a destination module, a defined pattern is communicated from the memory module along a master channel concurrent with the memory module providing data via one or more slave channels. Based on the phase of the defined pattern as it is received, the multi-link I/O interface feeds forward to the slave channels control signaling whose phase reflects a predicted noise pattern for the system. Each slave channel performs CDR by adjusting timing of its corresponding capture clock signal based on the fed forward control signaling and based on feedback signaling for the corresponding slave channel, whereby the feedback signaling reflects an error measurement between a phase of a capture clock signal and transitions in received data.
