Hi,

If the optimized filters subroutines exceed 50% of MIPS, as shown in attached figure.

Can I run the ADAU1442 in 96KHz?

Hi Debones,

At 96 kHz, you have 1792 Instructions available to execute your algorithm.

What is the cycle count given at the top of the compiler output window? Something like this?

Is like the attached figure.

But only run in 48 KHz, even if the instructions are at a half of the instructions.
