Missing implementation for arm_fir_decimate_f64 #154

Closed torfinnberset closed 4 months ago

torfinnberset commented 4 months ago

Currently, there is an implementation for arm_fir_f64, but there is no equivalent arm_fir_decimate_f64 as there are with the f32 variants of the same functions.

I could provide a reference implementation PR based on arm_fir_decimate_f32 if desired (removing any f32 intrinsic optimizations)

@torfinnberset Thanks. Don't hesitate to submit PR. Note that currently I won't be able to quickly test / merge your PR because I am working on other things. But I'll do as soon as I can find some bandwidth.
