biquad in 674x dsplib

Expert 1215 points

Hi,

I wonder when the biquad asm optimization will be available. It seems all you have to do is to fix the C671x asm running on C674x bug. Just curious, won't C671x binary run on C674x automatically?

Thanks

 

  • There's no plan for hand-optimized kernels in the 674x dsplib.  It's less buggy, easier to modify, and can more easily take advantage of new features in future cores (i.e. recompile).  674x is object compatible with 671x so you can certainly use the old kernel.  IIRC that algorithm improperly disables interrupts in the original 671x assembly version, part of the reason we moved to C code.

  • So you mean you are is okay with the performance as is. This is disappointing.
