摘要： A method for filtering an angular signal which avoids errors in averaging and differencing operations. Components of a hue signal are separated into groups based upon the sign of a corresponding filter coefficient ai for the respective component and the range of the hue component value vi. A weighted mean is computed for each of the groups. The weighted mean of the resulting values having positive filter coefficients and the weighted mean of the resulting values having negative filter coefficients then are derived. The computed value is redefined if needed to be in modulus 2&pgr;. The weighted distance of the two values then is derived. The result is the filtered hue value for a given image data pixel. A filtered hue value is obtained in the same manner for each image pixel of a desired image object or of a given image frame.

摘要： A central audio hub, comprising an audio switch, a bus matrix, and an audio buffer, is triggered to read audio samples of an audio stream from the audio buffer. The central audio hub routes the audio samples via the bus matrix to one or more surrounding audio modules such as an audio codec and an audio interface communicatively coupled to the central audio hub. The audio stream may be directly from an external application processor or from an external DDR. With the audio stream from the DDR, a DMA controller may fetch the audio samples from the DDR in response to a request received from the audio buffer, and store the fetched audio samples into the audio buffer for routing. The audio switch may be triggered at a determined sampling rate to read the audio samples from the audio buffer utilizing a determined sample format, and to route the audio samples to the surrounding audio modules.

摘要： An audio codec in a baseband processor may be utilized for mixing audio signals received at a plurality of data sampling rates. The mixed audio signals may be up sampled to a very large sampling rate, and then down sampled to a specified sampling rate that is compatible with a Bluetooth-enabled device by utilizing an interpolator in the audio codec. The down-sampled signals may be communicated to Bluetooth-enabled devices, such as Bluetooth headsets, or Bluetooth-enabled devices with a USB interface. The interpolator may be a linear interpolator for which the audio codec may enable generation of triggering and/or coefficient signals based on the specified output sampling rate. An interpolation coefficient may be generated based on a base value associated with the specified output sampling rate. The audio codec may enable selecting the specified output sampling rate from a plurality of rates.
