摘要： 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.

摘要： This disclosure describes techniques for processing audio files that comply with the musical instrument digital interface (MIDI) format. In particular, various tasks associated with MIDI file processing are delegated between software operating on a general purpose processor, firmware associated with a digital signal processor (DSP), and dedicated hardware that is specifically designed for MIDI file processing. Alternatively, a multi-threaded DSP may be used instead of a general purpose processor and the DSP. In one aspect, this disclosure provides a method comprising parsing MIDI files and scheduling MIDI events associated with the MIDI files using a first process, processing the MIDI events using a second process to generate MIDI synthesis parameters, and generating audio samples using a hardware unit based on the synthesis parameters.

摘要： 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.

摘要： Efficient memory fetching techniques are described that can improve data fetching during a motion compensation decoding process. The techniques propose several different memory fetching modes that may be very efficient in different scenarios of the motion compensation decoding process. A motion compensator may a particular memory fetch mode from a plurality of possible modes on a case-by-case basis for the memory fetches associated with a motion compensation decoding process of a macroblock. The techniques described herein may be particularly useful when fractional interpolation to sub-integer pixels is used in the inter-frame compression.
