Functions for managing resources

Most Natural Access functions implicitly use processes that run on the DSP resources. For example, adiStartToneDetector starts the tone detector function running on a DSP. adiStartRecording starts one of many voice compression functions running on a DSP. AG boards are shipped with default configurations that make the most commonly used functions available.

Note: It is not feasible or practical to make every possible function simultaneously available to an application.

This topic lists default functions and custom functions available for AG 2000 boards.
