Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

Power saving techniques in computing devices

A device and method for communicating, via a memory-mapped communication path, between a host processor and a cellular-communication modem are disclosed. The method includes providing logical channels over the memory-mapped communication path and transporting data organized according to one or more cellular communication protocols over at least one of the logical channels. In addition, the method includes acknowledging when data transfer occurs between the host processor and the cellular-communication modem, issuing commands between the host processor and the cellular-communication modem, and communicating and managing a power state via one or more of the logical channels.

Hardware accelerated communications over a chip-to-chip interface

In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

Methods and systems for resizing multimedia content based on quality and rate information

This disclosure describes techniques for controlling a perceived quality of multimedia sequences to try to achieve a desired constant perceptual quality regardless of the content of the sequences. In particular, an encoding device may implement quality control techniques to associate a sequence segment with a content 'class' based on the content of the segment, determine a perceptual quality metric of the sequence segment, and adjust at least one encoding parameter used to encode the segment is encoded such that for the perceptual quality of the sequence segment converges to the desired quality.

Methods and systems for quality controlled encoding

This disclosure describes techniques for coding mode selection. In particular, an encoding device determines whether or not to code a block of pixels in a coding mode currently being considered for selection using information associated with at least one other coding mode with a different block partition. In one aspect, the encoding device uses information associated with at lest one coding mode that has block partitions that are sub-partitions of the block partitions of the coding mode currently being considered for selection. Additionally, the encoding device may use information associated with another coding mode that has the same block partitions as the coding mode currently being considered for selection or information associated with the coding mode currently being considered for selection.

Coding mode selection using information of other coding modes

A method and system for coding mode selection using estimated coding costs. To provide high compression efficiency, for example, an encoding device may attempt to select a coding mode for coding blocks of pixels that codes the data of the blocks with high efficiency. To this end, the encoding device may perform coding mode selection based on estimates of coding cost for at least a portion of the possible modes. The encoding device may estimate the coding cost for the different modes without actually coding the blocks. In fact, in some aspects, the encoding module device may estimate the coding cost for the modes without quantizing the data of the block for each mode. In this manner, the coding cost estimation techniques may reduce the amount of computationally intensive calculations needed to perform effective mode selection.
