Abstract: In one embodiment, this disclosure provides an encoding device comprising a mode selection engine that performs mode selection for intra-prediction encoding regardless of whether the encoding device is programmed to comply with first encoding standard or a second encoding standard. The device also includes a first encoder to perform the intra prediction encoding according to the selected mode in compliance with the first encoding standard when the encoding device is programmed to comply with the first encoding standard, and a second encoder to perform the intra-prediction encoding according to the selected mode in compliance with the second encoding standard when the encoding device is programmed to comply with the second encoding standard. The techniques can simplify mode selection in support of multiple different intra-prediction encoding standards.

Abstract: This disclosure describes techniques for generating a set of data points that form a triangular wave having a desired gain and a desired frequency. In one example, the method includes the step of (a) determining an increment value based on the desired frequency and the desired gain of the triangular wave. The method further includes the step of (b) adding the increment value to a current data point to generate a next data point, the current data point and the next data point forming a subset of the set of data points. The method further includes the step of iteratively performing (a) and (b) to generate the set of data points that form the triangular wave.

Abstract: This disclosure describes techniques that make use of a plurality of hardware elements that operate simultaneously to service synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises storing audio synthesis parameters generated for one or more audio files of an audio frame, processing a first audio synthesis parameter using a first audio processing element of a hardware unit to generate first audio information, processing a second audio synthesis parameter using a second audio processing element of the hardware unit to generate second audio information, and generating audio samples for the audio frame based at least in part on a combination of the first and second audio information.

Abstract: The disclosure describes image processing techniques useful for devices that support image processing of different sized images. The techniques can be used in many contexts, and may be particularly useful for front-end image processing of small viewfinder images and large still images captured by the device. In one embodiment, this disclosure provides a method comprising capturing a first image with a device, processing the first image using line buffers sized to accommodate an image width of the first image, and capturing a second image with the device, wherein the second image has an image width larger than the image width first image. The method also includes processing the vertical stripes of the second image using the line buffers, wherein the vertical stripes of the second image define widths that fit into the line buffers.

Abstract: This disclosure describes an organizational scheme for memory that is useful for image processing. A memory controller architecture is also described, which takes advantage of the organizational scheme. The organizational scheme and controller architecture is particularly useful for high performance, high quality image processing of images that form a video sequence, but may also be applied in other image processing settings. The described techniques and organizational structure of the memory also allows the memory to be shared for other storage applications of a video device.

Abstract: Various aspects include methods for managing memory subsystems on a computing device. Various aspect methods may include determining a period of time to force a memory subsystem on the computing device into a low power mode, inhibiting memory access requests to the memory subsystem during the determined period of time, forcing the memory subsystem into the low power mode for the determined period of time, and executing the memory access requests to the memory subsystem inhibited during the determined period of time in response to expiration of the determined period of time.

Abstract: This disclosure describes techniques that make use of a waveform fetch unit that operates to retrieve waveform samples on behalf of each of a plurality of hardware processing elements that operate simultaneously to service various audio synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises receiving a request for a waveform sample from an audio processing element, and servicing the request by calculating a waveform sample number for the requested waveform sample based on a phase increment contained in the request and an audio synthesis parameter control word associated with the requested waveform sample, retrieving the waveform sample from a local cache using the waveform sample number, and sending the retrieved waveform sample to the requesting audio processing element.
