Reaching Processor Cycles limit  on ADAU1761

Hi everybody,

is there an indication from the compiler when the number of processor cycles is completely used?


Often I create applications with a lot of filters and other blocks that compile correctly and don't utilize all of the resources,

but when the application is run I get a sort of background whistle at high frequency.

I suspect that the needed processor cycles are more than those available because if I remove, for instance, a filter block

the whistle disappears (after recompiling and uploading), and if I add the block again it comes back.


From what I see there is no error message from SigmaStudio about reaching the processor cycle limit ... Is it possible to know how many cycles per sample are left ? Am I right or is there a different explanation?
