Debug features
The PL041_AACI component has no debug features.
Verification and testing
The PL041_AACI component has been tested using the ALSA driver for this component under
Linux.
Performance
The PL041_AACI component relies on a timed callback from the simulation so might have a
small impact on simulation performance. The ability to play audio through this component
depends on the AudioOut Component in use and on the performance requirements of the
software running on the simulated system. The rate of FIFO draining is controlled by the audio
output to which the component is connected. This might not correspond to the rate that would
be expected from the reference clock.
Library dependencies
The PL041_AACI component has no dependencies on external libraries.
5.4.9 AudioOut_File component
The AudioOut_File component implements and audio output suitable for use with the
PL041_AACI component. It writes raw 16 bit 48KHz stereo audio data to a user specified file.
Figure 5-28 shows a view of the component in System Canvas.
This component is written in LISA+.
