mixing the StarterWare mcaspPlayBk in a DSP/Bios application.

Hi,

The context is that I want to have an efficient audio engine but have the ability to support DSPLink. So I started a simple bios "helloworld" program, then copied the content of mcaspPlayBk.c into hello.c. Basically it seems to run and passing audio correctly, but the problem is the performance. With the original mcaspPlayBk, I can set the audio frame size to 16 samples and it still runs without dropping audio. But with the DSP/Bios mixed in, audio dropping happens even at a frame size of 1000. I am guessing some sort of resource confliction is causing this.

Can someone shed some light?

Thanks
