摘要： A display processor includes an interface unit, an instruction processor, a synchronization unit, at least one processing unit, and a device buffer. The interface unit receives input image data (e.g., from a main memory) and provides output image data for a frame buffer. The instruction processor receives instructions (e.g., in a script or list) and directs the operation of the processing unit(s). The synchronization unit determines the location of a read pointer for the frame buffer and controls the writing of output image data to the frame buffer to avoid causing visual artifacts on an LCD screen. The processing unit(s) may perform various post-processing functions such as region flip, region rotation, color conversion between two video formats (e.g., from YCrCb to RGB), up/down image size rescaling, alpha-blending, transparency, text overlay, and so on.

摘要： Image processing techniques are described that reduce the amount of bandwidth required to read an image from memory for display. According to the techniques, a processor stores low change rate display layers in a memory such that a processor can read the display layers from the memory using a reduced amount of processing resources. An overlay module blends low change rate display layers into a combined overlay layer. A processor reads the overlay layer from the memory and selectively processes the overlay layer based on processing information for the overlay layer recorded in memory. The processor then blends the overlay layer and a high change rate video display layer to update a single image for display according to a high change rate. In addition, the overlay module updates the overlay layer based on the low change rate display layers according to a low change rate.

摘要： Methods, systems, and devices for automatically changing the manner in which a tag unit communicates with one or more access points based on the tag unit's mobility state are described. A tag unit may transmit ultra-wideband (UWB) signals in a low update mode while in a stationary state. The tag unit may transmit UWB signals in a high update mode while in a mobile state. The tag unit, an access point, and/or a tracking management server may determine a tag unit's mobility state and adjust an update mode based on the mobility state.
