Hello,

I need to compute some values, for which I should use asinf() and sin() functions. I already

used math.h, but I am wondering if there exists some speed optimized library for this CPU,

which can be used?

The math libraries linked should be efficient and targeted to your CPU. The M3 doesn't have an FPU, so no opportunity to select/deselect that. Check your tool chain documentation for additional details, and configurations. You could Google for specialized math libraries/algorithms.

Review you algorithm for other opportunities to optimize or where/when to use different levels of precision.
