DSPLink on the Mistral EVM

Hi,

Regarding your DSPLink loop project example, what is the best case round trip (i.e. ARM-->DSP-->ARM)  time I can expect when looping a 1k byte buffer for the "tsk" based version of the project?  What about the "swi" version? 

I'm currently measuring approx. 350 usec for the "tsk" based version and this seems excessive.

 

Thanks,

Len
