摘要： Electronic devices incorporating a heat dissipation feature include an enclosure, and at least one heat-generating component positioned within the enclosure. The heat dissipation feature is sufficiently coupled to the at least one heat-generating component to facilitate conductive heat transfer from the heat-generating component. The heat dissipation feature includes a plurality of protrusions exposed externally to the enclosure. A thermally insulating material may be disposed on at least a tip portion of at least some of the protrusions. The thermally insulating material is selected to provide a touch temperature that is below a predetermined threshold. In some instances, the thermally insulating material can provide such a touch temperature by selecting the material to include properties for thermal conductivity (k), density (ρ), and specific heat (Cp) such that the product of k*ρ*Cp results in a value less than a product of k*ρ*Cp for human skin.

摘要： A video encoder/decoder includes a vector pipeline unit and is configured only once by a processor to encode/decode data in accordance with any one of the JPEG, MPEG1, MPEG2 or MPEG4, H.261 or H.263 compression standards. The configuration data is stored in a configuration register of the video encoder/decoder. An optional ROM stores the configuration data for subsequent reading and loading—by the processor—into the configuration register. The vector pipeline unit includes: a run-length decoder, a binary arithmetic logic unit, a binary multiplier/divider, an accumulator, a barrel shifter, a round/modify unit, a saturate logic unit, a status register and a run-length encoder. Each component of the vector pipeline unit is optionally enabled or disabled. By disabling one or more components of the vector pipeline unit the power consumed by the encoder/decoder is reduced. The vector pipeline, after being configured continuously encodes/decodes vectors of data according to the configured standard, without requiring any additional configuration or software programming. The status register gathers statistical data on the saturated data and supplies the statistical data to the processor, thereby, further improving the performance of the video encode/decoder. The video encoder/decoder encodes/decodes data based on any other compression standard with additional configuration or software programming.

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.
