How to check dm365 audio encode performance is correct ?

use mp3 encode / 64Kbps / 48K sample rate , the DM365 cpu loading is 55%~65% from demo ap message .

Thisperformance is correct in DM365 ?

Lucas,

Pls go to the docs folder of audio encoder and you find the codec datasheet (DS). You can find the CPU loading and the test case there.

Yes, i see this document.

DM365 is 320MHz CPU , this document show in MP3/128K encode , only need 27.9MCPS/peak.

But my test is only 64Kbps/48K sample rate, cpu load is over 50% .

if change to 128Kbps/48K sample rate , cpu load is over 70%.

What is i misstake ?

Lucas,

Most of the performance issues we have seen with DM365 ARM codecs are related to using or not using the cache. Please make sure the cache is enables. Search the forum on this topic if you need help about how to do that

Thanks
