Hi Dean, It should work for 24kec, 34kc and 74kc cores.

I suggest you try it. I do know that it requires the dsp extensions, but it may work on a 24k. Just change the -march=74kc and see if it works.

Hi All, First time poster to this group, please ignore my ignorance? I?m trying to use Opus 1.1 on a 400MHz MIPS 24k CPU (AR9331, specifically, like in the Arduino Yun). I?ve successfully built (I think) opus-1.1 and opus-tools-1.8 and they run, but are dog slow. opus-1.1 does have the ?enable-fixed-point option set, as this chip only has soft-float. My short test file (less than one

All those running Opus on MIPS should be interested in some new MIPS-specific optimizations contributed by Imagination Technologies. For now you will need to use Makefile.mips to build. Feedback on this new code is welcome. Cheers, Jean-Marc

Thanks for this. There?s not much documentation there. It appears that these optimizations are for MIPS 74K only and don?t apply to 24K-based builds, correct?
