摘要： An efficient low latency buffer, and method of operation, is described. The efficient low latency buffer may be used as a bi-directional buffer in an audio playback device to buffer both output and input data. The audio buffer includes two modes of operation. The first mode replaces large segments of data at a first rate, and the second mode replaces smaller segments of data at a second rate, higher than the first rate. The first mode may make efficient use of the buffer for the output, data while the second mode may provide low latency for the buffering of the input data.

摘要： An efficient low latency buffer, and method of operation, is described. The efficient low latency buffer may be used as a bi-directional memory buffer in an audio playback device to buffer both output and input data. An application processor coupled to the bi-directional memory buffer is responsive to an indication to write data to the bi-directional memory buffer reads a defined size of input data from the bi-directional memory buffer. The input data read from the bi-directional memory buffer is replaced with output data of the defined size. In response to a mode-change signal, the defined size of data is changed that is read and written from and to the bi-directional memory buffer. The buffer may allow the application processor to enter a low-powered sleep mode more frequently.

摘要： A portable electronic device provides audio output, such as from a media player application controllable by an ultrasonic remote control signal. Audio processing circuitry, which is normally configured to process audio signals in the human audible range, is configured by a controller to operate in an ultrasonic signal processing mode to detect an ultrasonic control signal, such as generated by a specialized headset. Such a configuration permits the portable electronic device to process ultrasonic control signals using native audio processing circuitry, without the need to add expensive hardware. The ultrasonic signal processing mode is initiated in response to a detected ultrasonic signal processing condition, such as detection of an active media player application or other application software or system software having an audio output function.
