== Performance ==
 
Here are some test results I measured on my IGEPV2 board.<br>
Decoding an aac music file using software decoder (faad) requires 60% load (top output).<br>
Decoding the same file using the DSP TI framework results in 4% CPU load (top output) and 176kbps / 21 fps DSP "load" (dmaiperf output).<br>
<br>
To get performance figures from the DSP add dmaiperf in the pipeline.<br>
<br>
I used the following pipelines:<br>
 
*gst-launch -v filesrc location=sample.aac ! faad ! audioconvert ! audioresample ! alsasink
 
*gst-launch -v filesrc location=sample.aac ! TIAuddec1 codecName=aachedec engineName=codecServer ! dmaiperf ! alsasink sync=false
